Elias, congrats. The ChemTalk team has been talking about this same experiment, and we also suspected the 50% H2O2 plus KI combination. We knew KI was a likely candidate because of its lower toxicity and easier clean-up which would be attractive to Rober's team. Based on your experiments, we feel fairly certain that you are correct. Excellent job on this video, and we hope you had fun trying to contain the foam that almost flew away. As always, looking forward to the next video.
Thanks. Another parent from a local homeschool group was talking about possibly doing a devils toothpaste demo sometime next year, and I was so confused because Mark Rober didn't reveal the recipe and I just had to find out if anyone even knew it before asking more. I bet they or their spouse are teachers at the local university if they know how to get hold of that concentration of hydrogen peroxide. I'll ask about all the safety precautions to be extra sure, but I imagine if they know how to get hold of the chemicals, they're familiar enough with chemistry to take the proper precautions without my needing to. I hope someone has a good infrared thermometer and we can compare the heat output of the 2 reactions. This would be a good opportunity to talk about why the heat forms and whats happening on a molecular level.
You are welcome! Hydrogen peroxide is a lot more dangerous in the sense that you get in trouble with the law. With proper safety precautions and knowing what you can and can't do it is very managable. You just have to be careful.
@@EliasExperimentswe absolutely will. While I ended up not going into chemistry myself, I did get a technical degree in geoscience, and I understand the dangers from when I took my chemistry classes. I'm not about to do anything that would put my kids at risk
I remember our city's mad amateur scientist had his own high concentration H2O2 making machine, and going so far with a different thing, he is now serving a lifetime in prison.
Honestly while it did look very similar Marks explosion looked like it was denser and closer to a liquid state rather then being fluffy and looser looking. While I think you did a great job in getting it very close to his recipe I think there's still something missing... It may just be a natural variation that happens by chance, but if I'm not mistaken once Marks recipe reacted it stopped reacting pretty quickly rather then continuing the reaction for some extra time after like yours did. It's very possible my observations are wrong as it might just be that Mark didn't give enough of a look at how long his reaction would last and only showed the initial reaction, but I suspect there's something else in the mix to ensure the reaction happens as quickly as possible so after the initial expansion there wouldn't be anything left to continue reacting afterwords due to it having reacted all at once. I could very easily be wrong, but that's just what it looks like to me especially looking at the comparison shot in your vid with them side by side.
@@matejbulik7962 that is also very likely a possibly... Probably more likely then my guess at their being another compound. Guess someone would just have to experiment a bit to get it right
Well in Marks first video about that the reaction kept going quite similarly to how it went in my video. The texture of the reaction mixture looks a bit different every time you repeat the experiment. In his second video he used pistons to mix the reactants a lot faster, so that helped to avoid that problem. I also agree with @Matej Búlik Thank you for the very detailed feedback though!
@@matejbulik7962 he said as much in a video about a devils toothpaste party. basically he's mixing peroxide+? into a simillar amount of soap and water that elias did but from the bottom so as to get a bit of dellay and for the foam to stop (eventually)
An impressive, and humorous, investigation - proving, once again, that the simplest answer is most often the correct one. Having subscribed after finding your solution in this video, I'm looking forward to more of them.
Great job in reverse engineering that experiment! It takes balls to concentrate H2O2 up to and over 60% & the dangers of it exploding spontaneously are very real above 70%. Like yourself, I was intrigued by Mark's results & set out to uncover the secret recipe, i was able to do it in a different way though by using sodium iodide dissolved in hot water to saturation & chilled 35% peroxide. If you get an opportunity, you should give it a try as well to confirm my findings. Good luck & keep up the good work, stay safe. Fyi-I chilled the peroxide so that there was time to fully add the sodium concentrate & yeild a complete reaction else most of it would get pushed out in the initial foam onto the ground.
Thank you for the feedback! Did you film your experiment, so that you can share it? In my experience it was a problem when the H2O2 was too cold, because then the reaction started quite a bit slower then mark's reaction.
@@EliasExperiments no sadly I'm extremely camera shy & an old school pencil/paper documentation kinda nerd so no video at this time. If I end up buying another 5gal of 35% I'll make a video and send you a link to it. In regards to the temps & reaction speeds; i too observed considerable lethargy when using the KI solution (@ room temp) & 35% H2O2 chilled to 40F in contrast to heated components. Hence, i was quite surprised when i switched catalysts to NaI & observed what i can only describe as an explosive foamy mess making goodness. Unfortunately, I had only a half liter of H2O2 left to repeat the experiment with but given the much smaller quantity it was only enough to do a single test, but the results were the same.
It really stinks when someone tries to use security through obscurity, especially when it's a two-component mix and we know one of those is some concentration of hydrogen peroxide. Does that really do anything to prevent people from reproducing the experiment when the main barrier to this is being able to source the ingredients? It could be argued that this actually endangers people since they will be working from guesses, potentially overshooting the concentrations like you did, with similar or more extreme results. Maybe this gives Mark plausible deniability if someone gets hurt, but ultimately I think it has far more risk of harming someone who wants to do cool stuff like him, and has to do dangerous testing to get the same effect.
Thanks for sharing this, I really appreciated. I would like to ask a few things, since I'd like to do this experiment but using a smaller quantity and 30-35% H2O2. 1- you are using 50% KI solution (300g water+300g KI) but since KI is very soluble you probably could have used less water. If you used a solution with 150g of water and still 300 g of KI, do you think the result would be different in any way? 2- will the concentration of H2O2 decrease over time? Since I'm planning to buy a 20L-35% bottle (cheaper), I was wondering if this concentration will be stable over the years or it will naturally transform in H2O+O2. Thanks in advance.
Thank you for watching. 1- of course you can change stuff like that, if it gives you a better, identical or worse result I don't know. 2- Depends on how it is stored. If it is a very pure substance and no contaminants get inside it should be quite stable. Storing it in a cool and dark place also helps. Mine has been stable for a couple of years so far, even though I never determined any concentrations. It might degrade a little bit, or the concentration might increase if water can evaporate.
I was thinking that he was using hot peroxide and potassium iodide, because in one of the shots when they were pouring the barrels it was fuming. I guess it could be more concentrated and also heated up.
Well as you can see in the video, heating it up was not necessary. But if the peroxide is too cold in the beginning there will be a short delay. About heating up 35 % H2O2 that is actually a great idea, I didn't try yet. But I doubt that is what he did, cause of the small scale test in the plastic cup.
When it degrades it is dish soap, food color and a tiny amount of potassium iodide with water. Basically harmless assuming your dish soap is harmless. Potassium permanganate gives a stronger reaction I think. But that leaves a more toxic residue.
If I had a nickel for each time the hidden secret ingredient for a chemistry demonstration was Hydrogen peroxide, I'd have 2 nickels. That isn't a lot and it's actually not that surprising that it happened twice.
Edit* When you know what you are doing and only small amounts(like a drop)! Do not ever use this(and other dangerous) chemical when you haven't studied chemistry at an university! Can't stress this enough. Not very nasty. Even if it touches skin, it turns white for a day but other than that it's useful for many things in chemistry. Urea peroxide for example. Also, 50% peroxide is sold in some countries.
If you are not careful with such highly concentrated peroxide much more nasty things can occur then having a white skin. Unplanned explosions to just name one example.
@@EliasExperiments Yeah, of course, but mostly I meant that I've had worse burns from other chemicals before I studied chemistry and didn't have any practical experiences. Even 35% HCl burns very badly when opening the bottle because of the gas that comes out. Diethyl ether is way more dangerous because it can explode by opening the bottle after 8 months. The real danger with concentrated H2O2 is when it mixes with other household chemicals. Not gonna say which ones here but you should know. There can be way more dangerous gases produced that are life threathening at under 2ppm(6.3mg/m3) when somebody uses this and something else for cleaning. These are the things I'm really concerned about and I'm happy they banned highly concentrated H2O2 cleaning products. But thanks for caring, I'll edit my comment so others know what I meant.
@@EliasExperiments Btw, you know chemistry well enough so I'm gonna tell you a good use for conc. H2O2. CaC2 + H2O2 = Acetylene + Oxygen which is more fun than without oxygen. You can use it for welding or if you're crazy enough to put it inside a balloon, then be aware that 1 gram of this gas is louder than a shotgun shot with a strong shockwave.
@@EliasExperiments But be careful, if you add too much H2O2, it will start to foam and turn into a Ca(OH)2 and H2O2 vulcano. It will also heat up and can cause an explosion when not in an ice bath.
Well that would take me quite a while to make, but maybe some day. :D But I doubt it would produce a lot of foam, cause the foam was already quite unstable at 60 % H2O2.
@@EliasExperiments I think it's critical that some of the water stays liquid for it to foam. If I recall, over about 68(?)% the amount of heat created by decomposing hydrogen peroxide is enough to boil out all the water, leaving hot oxygen and pure steam.
@Cloaker Well I couldn't agree less with the comparison to nitroglicerin. First of all nitroglycerin is extremly toxic, which is a huge danger added. It doesn't decompose with a nice woosh like the H2O2 but instead detonates. If that would have been 5 L of nitroglyerin detonating, that video would have never been uploaded and there probably wouldn't be a lot left of me.
Having found your favoured peroxide/reagent ratio, have you tried better bubbling agents than dish soap? There are many better, from pro kids entertainer bubble mixes to those used in gastronomy. A firmer, more stable bubble structure will capture more of the rxn I'd guess?
Something like soy lecithin, or maybe a gum of some kind like xanthin. Those can create pretty strong bubbles. The first is used in making culinary foams, and the second is used for making culinary gels.
@@EliasExperiments, and floating foam at over 110 degrees C(that’s a very low estimate considering the 100 C River’s experiment was at) that keeps its core hot.
You don't want to get anywhere near 95% H2O2. A tiny drop on your skin will eat through your flesh and damage your nerve endings and if it gets into your blood stream will poison you.
@@EliasExperiments awesome thank you! I was able to find 35% at my local agricultural supply store and KI online. Any recommendations for getting it to 40-50% concentration? I’m doing a gender reveal for my wife and I. I’m sure 35% would do the job. But 50% will leave a memory!
@@lizanneroets7892 it went well, we ended up going with 30% because I didn’t want to invest in the equipment to make 50 But it was still a good reveal. The key to finding reasonably priced hydrogen peroxide for me was going to Ag/farm supply stores because they use it for animals. I only paid 15$ per gallon. Online I saw it was upwards of 50$ per gallon
I looked at the differences and the similarities and I figured out that yours is slightly over in the hydrogen peroxide. So maybe like 45%- 50% would be more accurate because his falls a lot quicker and rises later than yours.
@@EliasExperiments I mean I guess so, I was only trying to make a point, I dont want you to spend more money on the hydrogen peroxide... but I mean, sure if you will! I was just saying that his was more like elephant toothpaste in similarities than your experiment.
@@EliasExperiments But also reconsidering the fact that the measurements of the amount of the solutions you put in could have been just a slight difference.
Yes it is certainly hard to tell. If I do make another video it will also include the new footage on mark robers newest video with the flaming glove and foam. And while I am at it I could test your idea.
@@EliasExperiments dont bother with the glove its false lead. the flames and smoke come from the bottom and the inside of the glove rather than the top where the chemical was applied
50% hydrogen peroxide is easy to get here in Thailand, just a few bucks for a big bottle. But our potassium iodide comes in powder form.... Could I add the powder as is? Or could I add it to warm water to make a solution? I'm just a mom wanting to do the experiment for my kids (after testing from a safe distance of course)
Potassium iodide is always in powder form, but you can add an equal weight of warm water and you will get the required solution. But really be careful, 50 % hydrogen peroxide is no joke and it really hurts on your skin and is very dangerous to your eyes.
Thank you we are home school group of 10-year-old boys that really want to see an explosion don't worry we'll be safe seriously. Smiling. We really do appreciate this. How else do young scientists develop?! We have adult supervision
Your recipe is likely closer to the original recipe by Mark Rober, but have you tried mixing H2O2 and NaOCl? This would likely produce a similar reaction(although not as long-lasting) to the Devil's toothpaste, with lower concentrations of both chemicals, as they are both strong oxidisers, which produce lots of oxygen very quickly when mixed. It's also cheaper that using KI as catalyst.
i wanna ask woh much time does it take to evaporate the hydoren poroxide and if i can just put it in the oven in like 100 or 80 degrees and alsow if can explode by itselve if its too hot?
Yes hydrogen peroxide can react quite violently if you are not careful as shown in this video. How quickly it evaporated depends on many factors, how big the surface is compared to the volume, how hot it is, how much air exchange you have, the pressure and humidity. If all factors are in your favor the concentration can increase dramatically over night, but if you make it too hot you risk destroying the hydrogen peroxide. So many things to keep in mind. Also if you are working with equipment that is not very clean it could also end poorly.
I’ve seen RUclips videos on concentrating hydrogen peroxide, but since I can only get my hands on 3% I haven’t bothered trying to reproduce their results.
I think its 50% H2O2+KI+Dish soap and food coluring and that "something else" is Catalase as it decomposes H2O2 the fastest,and its colorless and non toxic.
The thing with catalase is that it is very hard to mix quickly with H2O2. Potassium permanganate is a much faster catalyst, but also really difficult to mix, because it doesn't dissolve in water too well.
@@EliasExperiments What if Potassium Iodide and Catalase is mixed together in a water solution and then added quickly to hydrogen peroxide and the rest?
No that is not what I used, that would be way to expensive. I bought it from a chemcial supplier in this case laboratoriumdiscounter. But there are probably a lot of other chemcials suppliers that would sell it to you.
@@EliasExperiments I kind of thought so :) but you somehow made it sound like there is some additional "secret" to this hehe Is there a risk of explosion? anyhow, It seems I was able to just buy the 35% H2O2 online so I will try to make some tests with it :) Also, it seems KI and NaI are quite expensive I was thinking about trying with baking soda or yeast for catalysator... Is there a chance this will work? (I have heard yeast only do the job with low % H2O2)
Well if you don't know exactly what you are doing there are quite a few risks. Potassium permanganate is a lot cheaper catalyst that is way more active then KI. So you need a lot less, but I have never tested what concentration of potassium permanganate gives the same result as 50 % KI solution. Yeast also works but is a lot slower. So that is not really a good option.
Make sure to let me know, if you figure out at what concentration you can get it to work in a similar fashion to what you can see in this video. I guess it must be somewhere in the 1 % range.
@@EliasExperiments thank you my birthday is coming up and I wanted to do the one you did that was the same as mark rober and I hope everyone will like it. I’m only eleven so I’ve been trying to learn chemistry but I just started. Thanks 😊 Edit: sorry for commenting on a very old video I just thought that it was the same topic
Ich habe eine Frage bezüglich der Seife: ist das Natriumlaurentylsulfat der einzige Stoff der von der Seife reagiert? Also könnte man theoretisch auch einfach direkt nur Natriumlaurentylsulfat nehmen
Das weiß ich nicht ehrlich gesagt. Kann gut sein, aber das steht nicht auf der Spüli Flasche drauf und ich habe keine Analytik davon durchgeführt. Nach meiner Einschätzung könnte es mit Natriumlaurentylsulfat funktionieren, wenn Du es vorher löst.
What do you mean almost acidic? And how exactly does it catch fire? I haven't watched his new video yet, so I would need a better explanation from you in order to help you.
@@EliasExperiments in the newest video he shows how dangerous it is, he shows how somehow the reaction spontaneously combusted after it had already somewhat happened. And he shows whay it looked like to spill (I believe.) just the catalyst onto a pair of heavy duty gloves. In doing such, it catches fire and I believe it even melts it some as soon as it makes contact. Thanks for the reply!
I hardly believe that the catalyst can set a glove on fire. There are only a few liquids (That I can think of at least) that could do such things. And I am not sure if these liquids are any good in catalysing the decomposition of hydrogen peroxide fast enough. I might make another video about it at the end of this year or the beginning of next year, if no one else explained it well until that point. But I would also have to do quite a few experiments and a lot of research first to tell for sure. That is the best I can do for now.

@@EliasExperiments Yeah, of course, but mostly I meant that I've had worse burns from other chemicals before I studied chemistry and didn't have any practical experiences. Even 35% HCl burns very badly when opening the bottle because of the gas that comes out.
Diethyl ether is way more dangerous because it can explode by opening the bottle after 8 months.
The real danger with concentrated H2O2 is when it mixes with other household chemicals. Not gonna say which ones here but you should know. There can be way more dangerous gases produced that are life threathening at under 2ppm(6.3mg/m3) when somebody uses this and something else for cleaning. These are the things I'm really concerned about and I'm happy they banned highly concentrated H2O2 cleaning products.
But thanks for caring, I'll edit my comment so others know what I meant.
@@EliasExperiments Btw, you know chemistry well enough so I'm gonna tell you a good use for conc. H2O2.
CaC2 + H2O2 = Acetylene + Oxygen which is more fun than without oxygen.
You can use it for welding or if you're crazy enough to put it inside a balloon, then be aware that 1 gram of this gas is louder than a shotgun shot with a strong shockwave.
@@EliasExperiments But be careful, if you add too much H2O2, it will start to foam and turn into a Ca(OH)2 and H2O2 vulcano. It will also heat up and can cause an explosion when not in an ice bath.
Haha that sounds indeed very dangerous :D
man you derserve a subscribe
Thank you!
Thank you so much for this! I’ve been looking for this for ever
Glad I could help! ;-)
Now we need 100 percent H2O2.
Well that would take me quite a while to make, but maybe some day. :D But I doubt it would produce a lot of foam, cause the foam was already quite unstable at 60 % H2O2.
You might as well make nitroglycerin; even 50% is really volatile. en.wikipedia.org/wiki/Hydrogen_peroxide#Decomposition
@@EliasExperiments I think it's critical that some of the water stays liquid for it to foam. If I recall, over about 68(?)% the amount of heat created by decomposing hydrogen peroxide is enough to boil out all the water, leaving hot oxygen and pure steam.
@Cloaker Well I couldn't agree less with the comparison to nitroglicerin. First of all nitroglycerin is extremly toxic, which is a huge danger added. It doesn't decompose with a nice woosh like the H2O2 but instead detonates. If that would have been 5 L of nitroglyerin detonating, that video would have never been uploaded and there probably wouldn't be a lot left of me.
@Delta B Yes that is what I have also read. I guess you are quite right! :D
Is the potassium iodine Solution Calculated in volume or weight.
In weight. Calculating powders in volume is a highly inaccurate buisness.
Having found your favoured peroxide/reagent ratio, have you tried better bubbling agents than dish soap? There are many better, from pro kids entertainer bubble mixes to those used in gastronomy. A firmer, more stable bubble structure will capture more of the rxn I'd guess?
Well the point was really about reaction speed and the influence of the soap shoud be relatively low.
Something like soy lecithin, or maybe a gum of some kind like xanthin. Those can create pretty strong bubbles. The first is used in making culinary foams, and the second is used for making culinary gels.
I wonder what 95% or higher H2O2 would yield haha
Probably a pretty bad explosion. :D
@@EliasExperiments, and floating foam at over 110 degrees C(that’s a very low estimate considering the 100 C River’s experiment was at) that keeps its core hot.
You don't want to get anywhere near 95% H2O2. A tiny drop on your skin will eat through your flesh and damage your nerve endings and if it gets into your blood stream will poison you.
@@lifeisbetterwhenyourelax yes, interesting. *takes notes*

Dr. Strangelove is doing party tricks!
Oh no, how did you figure out my real identity?
Love the video, just to be clear, when you say 600gram 50% KI you mean 600grams of KI mixed in a solution of 50% water and 50% KI?
600 g 50 % KI means 300 g of KI mixed with 300 g of water.
@@EliasExperiments awesome thank you!
I was able to find 35% at my local agricultural supply store and KI online.
Any recommendations for getting it to 40-50% concentration?
I’m doing a gender reveal for my wife and I. I’m sure 35% would do the job. But 50% will leave a memory!
@@Nate-hq8no You can pour it in a very clean flat dish and let the water evaporate. Good luck!
@@Nate-hq8nohow did the gender reveal go?
I want to do the same for my brother
@@lizanneroets7892 it went well, we ended up going with 30% because I didn’t want to invest in the equipment to make 50
But it was still a good reveal.
The key to finding reasonably priced hydrogen peroxide for me was going to Ag/farm supply stores because they use it for animals. I only paid 15$ per gallon. Online I saw it was upwards of 50$ per gallon
I looked at the differences and the similarities and I figured out that yours is slightly over in the hydrogen peroxide. So maybe like 45%- 50% would be more accurate because his falls a lot quicker and rises later than yours.
Could be true yes. Good point I might make another video about this.
@@EliasExperiments I mean I guess so, I was only trying to make a point, I dont want you to spend more money on the hydrogen peroxide... but I mean, sure if you will! I was just saying that his was more like elephant toothpaste in similarities than your experiment.
@@EliasExperiments But also reconsidering the fact that the measurements of the amount of the solutions you put in could have been just a slight difference.
Yes it is certainly hard to tell. If I do make another video it will also include the new footage on mark robers newest video with the flaming glove and foam. And while I am at it I could test your idea.
@@EliasExperiments dont bother with the glove its false lead. the flames and smoke come from the bottom and the inside of the glove rather than the top where the chemical was applied
thank you, this is gonna be my science project.
Nice, I wish you all the best!
Yo lester !!

@@danstoisor4563 Kidnapped
@@callix9886 Oh no 😮
50% hydrogen peroxide is easy to get here in Thailand, just a few bucks for a big bottle. But our potassium iodide comes in powder form.... Could I add the powder as is? Or could I add it to warm water to make a solution?
I'm just a mom wanting to do the experiment for my kids (after testing from a safe distance of course)
Potassium iodide is always in powder form, but you can add an equal weight of warm water and you will get the required solution. But really be careful, 50 % hydrogen peroxide is no joke and it really hurts on your skin and is very dangerous to your eyes.
awesome brother!!! 💪🏽💪🏽👍🏽👍🏽👍🏽👍🏽👍🏽👍🏽👍🏽
Glad you liked it!!
We need more people interested and learning about chemicals
I 100 % agree!
Thanks for the recipe. A 50% solution isn't that hard to cook up from my stock solution.
Wait you cook H2O2? :D
how do you do it
ima use this for my science fair project
I wish you best of luck!
I hope to as well! We gotta share videos lol
mark is like, Hmm what now, they discovered the devils toothpaste, oh i know, hells toothpaste or no, satans toothpaste, no maybe hells toothpaste
Lol great idea! XD

Thank you we are home school group of 10-year-old boys that really want to see an explosion don't worry we'll be safe seriously. Smiling. We really do appreciate this. How else do young scientists develop?! We have adult supervision
Okay I wish you the best of sucess and hope you stay safe! :-)
What a madlad
That's just what I am. :D
This was great also , thanks for the information and doing all the add work.
My pleasure! :D
Wow well done!!!
Thank you!
airport security boutta be absolutely flabbergasted😈
Lol why would airport security care about that?
Your recipe is likely closer to the original recipe by Mark Rober, but have you tried mixing H2O2 and NaOCl? This would likely produce a similar reaction(although not as long-lasting) to the Devil's toothpaste, with lower concentrations of both chemicals, as they are both strong oxidisers, which produce lots of oxygen very quickly when mixed. It's also cheaper that using KI as catalyst.
That is a great suggestion indeed! I will definetly try that!
Never heard of Mark Rober, so i seen yours 1st haha
Lol I guess that is really unusual, but with thousand of people watching stuff like that happens. XD
i wanna ask woh much time does it take to evaporate the hydoren poroxide and if i can just put it in the oven in like 100 or 80 degrees and alsow if can explode by itselve if its too hot?
Yes hydrogen peroxide can react quite violently if you are not careful as shown in this video. How quickly it evaporated depends on many factors, how big the surface is compared to the volume, how hot it is, how much air exchange you have, the pressure and humidity. If all factors are in your favor the concentration can increase dramatically over night, but if you make it too hot you risk destroying the hydrogen peroxide. So many things to keep in mind. Also if you are working with equipment that is not very clean it could also end poorly.
@@EliasExperiments thanks bro
Great video - thanks:)
Thank you for the kind feedback!
I feel like mark rober used the following:
Hydrogen peroxide
Potassium
Soda
Soap
Mentos
How do you come up with that? Soap and hydrogen peroxide is correct, but potassium metal would be far to dangerous and soda and mentos wouldn't help.
@@EliasExperiments you would with hydrogen peroxide, soap and soda together. Then you put the potassium iodide.
Don’t worry about the mentos
Maybe baking soda?
Baking soda would be quite useless in that reaction. For baking soda to foam you need acid.
I’ve seen RUclips videos on concentrating hydrogen peroxide, but since I can only get my hands on 3% I haven’t bothered trying to reproduce their results.
Well yeah starting from 3 % that would be quite ambitious. XD
Excellent science! Well done!
Thank you!
I think its 50% H2O2+KI+Dish soap and food coluring and that "something else" is Catalase as it decomposes H2O2 the fastest,and its colorless and non toxic.
The thing with catalase is that it is very hard to mix quickly with H2O2. Potassium permanganate is a much faster catalyst, but also really difficult to mix, because it doesn't dissolve in water too well.
@@EliasExperiments What if Potassium Iodide and Catalase is mixed together in a water solution and then added quickly to hydrogen peroxide and the rest?
Well it would probably react quite simlar to what was shown in this video.
The stuf that flew away could be called "Angels Toothpaste" describing how it floats.
Lol you are the second person now to suggest that idea :D I really like it.
See, now I'm wondering what happens at 70% concentration.
There probably won't be much left. :D
Backyard scientist mentioned he concentrated peroxide, by putting it in a bit of water and letting the water evaperate into the air...and repeating.
That is what I did too, but apparently with more sucess and I didn't put it in water, because what would be the point?
What happens 100% peroxide
That would be quite dangerous and might explode. However I would have to test that first.
I hope this video doesnt gets demonitzed
I don't see why it should
Lol i was theorizing what the recipie was then I searched it, I love the internet.
Haha always do your reasearch first I guess :D
I was wondering where you get the potassium iodide? I tried looking it up and nuclear fallout protection stuff comes up. Is that what you used?
No that is not what I used, that would be way to expensive. I bought it from a chemcial supplier in this case laboratoriumdiscounter. But there are probably a lot of other chemcials suppliers that would sell it to you.
What a mad man thank you!!!
Thank you for watching :-)
Love your work.
Thank you!
very good
Thanks
Make this guy famous
Lol thank you!
Is this guy german or some other nationality. I don't even care, but I love him.
Yes I am germany, thank you!
This is soo cool :) can you point out some source to increase the concentration from 35% to 50%?
I would love to recreate this!
Thanks! I don't have an exact source, but letting the water evaporate pretty much does the trick. ;-)
@@EliasExperiments I kind of thought so :) but you somehow made it sound like there is some additional "secret" to this hehe Is there a risk of explosion?
anyhow, It seems I was able to just buy the 35% H2O2 online so I will try to make some tests with it :)
Also, it seems KI and NaI are quite expensive I was thinking about trying with baking soda or yeast for catalysator... Is there a chance this will work? (I have heard yeast only do the job with low % H2O2)
Well if you don't know exactly what you are doing there are quite a few risks.
Potassium permanganate is a lot cheaper catalyst that is way more active then KI. So you need a lot less, but I have never tested what concentration of potassium permanganate gives the same result as 50 % KI solution.
Yeast also works but is a lot slower. So that is not really a good option.
@@EliasExperiments Thank you for the Potassium permanganate tip :D its way cheaper! will test it for sure!
Make sure to let me know, if you figure out at what concentration you can get it to work in a similar fashion to what you can see in this video. I guess it must be somewhere in the 1 % range.
Who was that they were going to see Mark rober in the comments like "well played"
Lol Sciencebob has contacted me about this, but was not allowed to tell me if I got it 100 % correct, but he wrote that he liked the video.
What did you use for the other half of the patassuim iodide
Water
@@EliasExperiments thank you my birthday is coming up and I wanted to do the one you did that was the same as mark rober and I hope everyone will like it. I’m only eleven so I’ve been trying to learn chemistry but I just started. Thanks 😊

Only when you go too far you know how far you can go!

Very cool, how did you clean this mess up?
I just put it all in a box and waited for the foam to settle. :D

You are welcome. :-)
Ich habe eine Frage bezüglich der Seife: ist das Natriumlaurentylsulfat der einzige Stoff der von der Seife reagiert? Also könnte man theoretisch auch einfach direkt nur Natriumlaurentylsulfat nehmen
Das weiß ich nicht ehrlich gesagt. Kann gut sein, aber das steht nicht auf der Spüli Flasche drauf und ich habe keine Analytik davon durchgeführt. Nach meiner Einschätzung könnte es mit Natriumlaurentylsulfat funktionieren, wenn Du es vorher löst.
good work!
Thanks!
In his video it’s almost acidic, the catalyst. Even showing that the reaction sometimes catches fire. Would that happen with these ingredients?
What do you mean almost acidic? And how exactly does it catch fire? I haven't watched his new video yet, so I would need a better explanation from you in order to help you.
@@EliasExperiments in the newest video he shows how dangerous it is, he shows how somehow the reaction spontaneously combusted after it had already somewhat happened. And he shows whay it looked like to spill (I believe.) just the catalyst onto a pair of heavy duty gloves. In doing such, it catches fire and I believe it even melts it some as soon as it makes contact.
Thanks for the reply!
I hardly believe that the catalyst can set a glove on fire. There are only a few liquids (That I can think of at least) that could do such things. And I am not sure if these liquids are any good in catalysing the decomposition of hydrogen peroxide fast enough. I might make another video about it at the end of this year or the beginning of next year, if no one else explained it well until that point. But I would also have to do quite a few experiments and a lot of research first to tell for sure. That is the best I can do for now.
@@EliasExperiments understand. Thank you
@@EliasExperiments Why would you have to wait until next year to make a video?
Nice job!
