The yeast one with 3% hydrogen peroxide should not burn, so yes you can touch with gloves and it should be. It's only the 35% hydrogen peroxide that burns.
What is the measurement of potassium iodide crystals in the solution? I know that it's 2 tbsp of water; is it the same amount of the crystals? Perhaps just 1 tbsp?
Love the video!!! I currently have a 5000mL flask should I double the experiment or will the reaction for the 35% still have the same reaction? Wasn’t sure if our flask is wayyyy too big.
Wow that's a big flask! It'll still work, the resulting foam should expand enough. But it probably won't be as powerful if you use the amounts I use in the vid.
Packet of yeast: 8g 3 tbsp water: 44g (but 30g 4:1 may work better) 2 tbsp water: 30g Add KI until no longer dissolves, probably 100% 1:1 concentration
awesome, thank you for this video, I bought all the required stuff, they arrive tomorrow, I'll make a prototype, this sunday I'm going to the birthday of a person who wishes to see a volcano but we couldn't arrange travel plans in time so I'm making this miniature volcano instead
If you do the one with the stronger hydrogen peroxide, is it safe to touch the foam after it bubbles up? I want to do that with my kids if it’s touchable.
The foam isn't the concern, it's any unreacted hydrogen peroxide which would still be in liquid form. And that risk will still be there unless you let it sit for a very long time to decompose. If you use gloves and can wash it off/spray it off without direct contact you'll be fine.
My grandchildren and I have tried this with iodide and 35% peroxide. We were very disappointed because it did not “explode” into the air. It looked like the yeast when it poured over. Any hints?
Really? Hmm, it should be a pretty consistent reaction. Did your container have a narrow neck? Which type of iodide did you use (i.e. potassium iodide or sodium iodide?) How much iodide?
The foam will expand faster than with 6% or 3%, but it still won't spew out of the container or be as impressive like it can be with iodide because the heat limits the yeast.
The hydrogen peroxide is decomposing (breaking apart) into water and oxygen. This happens naturally but it usually takes a really long time. By adding a catalyst (the iodide or yeast), this reaction happens a lot faster.
I got it at a local health food store- (called Nature's Finest) in the refrigerated section. Depending on where you live it'll be pretty hard to buy online due to shipping regulations.
A durable plastic container should be fine as well, glass is just easier to clean. If you want it bigger, you definitely want a bigger container. Doubling all the ingredients but keeping the same size container won't produce that much bigger of a result. And you can just increase the amounts of ingredients in equal ratios to what I have in the video.
If you use the iodide I wouldn't touch the foam. It stains and could irritate your skin if there's any unreacted peroxide left over. If you use the yeast the foam is fine to touch.
Add some crystals into the 2tbsp of water and stir till it dissolves. Keep adding crystals until it no longer dissolves. You should be able to dissolve around 25 grams of it.
When you got the big reaction with the iodide & 35% peroxide did you still add the dish soap? Or was it merely just peroxide & dissolved iodide tablets in water?
@@justpeachie7004 hmm, it should dissolve with stirring, it usually only takes a few minutes to get it to dissolve. If you got the same bottle (100 grams), you should be able to dissolve 1/4 of the bottle fairly easily. Are you using purified or bottled water?
ive had one week to plan a gender reveal, the last few days it’s been so hard to find the actual recipe to a good reaction in elephant foam. it’s in 2 days now and the only things i have is 3% hydrogen peroxide, yeast, and povidone iodine. i’m trying to find out if i can get the 30% hydrogen peroxide and iodide capsule in store but so far i only see online 😭
NOTE: The peroxide link is only 30ml. You will need 120ml. Don't make my mistake. Make sure you change the quantity to four. We did a sex reveal and didn't have the big reaction I'd hoped for 😩. We will repeat the experiment in the summer just for fun.
Yeast is a living thing, vinegar is an acid, so they are very different. To get this specific reaction you need yeast or iodide. You could do a separate experiment where you combine the liquid soap with vinegar in the bottle and then add in baking soda. You'll at least get bubbles but it is a different reaction and will not look nearly as impressive.
Hey can I use like 20% hydrogen peroxide cuz i don’t wanna get that foam that big so yea if I 25% of hydrogen peroxide how much do I need for to add potassium iodide or whatever u called it pls answer this asap! I need to know if I cam cuz science fair is coming up very soon!!!
More H2O2 molecules packed tightly together (higher %) means more can be broken down quicker into O2 gas and H2O. So gas is being made faster with increasing % of H2O2.
In the video I used the catalyst as an independent variable (yeast versus potassium iodide). You could instead make different percentages of hydrogen peroxide be your independent variable (i.e. 3%, 6%, 12%, and 35%).
1:05 Can the 35% Oxygen Peroxide mix this be safely used to make Aircrete by mixing into a Portland cement slurry? Do the bubbles hold? will affect the Portland adversely?
I no nothing about aircrete. I can say that the bubbles have oxygen gas in them, and I suppose theoretically something viscous like wet cement could trap the gas... But it seems like a very messy and expensive way to get oxygen trapped in cement.
It's best to assume so in case there is unreacted peroxide, but most of the peroxide will have reacted and decomposed so all you have left is harmless water, oxygen, soap, and the iodine (meaning it can stain still). So theoretically it should be a lot safer to clean up.
Depends where you are. It's kinda hard to buy the 35% peroxide online due to shipping regulations (at least in the USA), so I got it from a local health food store (there's nothing healthy about it though...). And for the iodide it's pretty widely available online.
I assume you mean tincture of iodine, which is not the same thing as iodide and will not work well. The link is in the description, I used potassium iodide.
@@SquintScience Potassium iodide solid is 100% But when put potassium iodide in water I need 1KG for 1000 ML means 100% and it is very expensive. Put 100 gr in 1 liter of water. Does that mean 10% concentration in the water is enough? I don't think anyone dissolves 100% of potassium iodide in water. Thanks!
@@rikotube1100 Aw, I thought you were asking for the concentration you would buy it in (I don't know how familiar with chemistry you are). When dissolving, you want a supersaturated solution, so as much as will dissolve. If you're using 100 g iodide you'll only need about 70 - 100mL water. In the video I used about 35 grams iodide in 30mL water.
Amazing video, wanna try! Are the gasses this reaction produce safe to breath in? And if i made the experiment bigger, how can i clean it up, is it safe to touch when the foam melts down on the tarpaulin? Thanks, new sub here :)
Yep, you produce oxygen and water vapor, both safe to breathe. The biggest thing with cleanup is the iodide forms iodine which stains everything yellow. And it's a real pain to try to wash off. So I'd do it outside, if you do it on a tarp like I did you can just spray it off. The foam is just oxygen, water, soap, and iodide/iodine, so it should be safe to touch but it'll be really hot. The only concern would be if there's any leftover h2o2 it could burn/irritate skin.
Squint Science // Thank you!❤️ One more thing, i live in Norway and found out it’s illegal to have/buy peroxide over 12%.. should I then just use 3x more peroxide and mix it with iodide to get the same effect?😊
Ah, bummer. You can do that but it won't quite have the same effect as 30+% unfortunately. Depending on your level of risk, you could carefully try to boil the peroxide on low heat, but this could create some dangerous situations though... Some hair products have higher concentrations of peroxide, perhaps those can be bought over there?
@@SquintScience do you have a hair product I could buy? I was looking on Walmart and Amazon but I am not sure about the hair products that showed up in my search.
@@SquintScience Do you remember how much Hydrogen Peroxide 35% you had for the 30 grams of Potassium iodide @1:12? Half a cup like in previous experiment or more/less?
Could not get a reaction with yeast. Strange ...Got one with Potassium Iodide though. Wondering if I mix more Potassium Iodide if it would make the reaction stronger? Using 3% Hydrogen Peroxide...
Yeast is a bit finicky since it's a living thing. I'd suggest dissolving it in warm water and gently stirring for a few minutes before you add. And make sure your yeast isn't too old! For the iodide, you can try adding more but the 3% h2o2 is going to really limit how explosive the reaction is, so it probably won't make too noticeable of a difference. Good luck!
I assume you are referring to the steam. It's a hot reaction, could be leftover 35% hydrogen peroxide, so I wouldn't let them touch it just in case. If you do the 3% h2o2 it should be fine to touch.
If you plan on touching it I'd be more concerned about any leftover unreacted hydrogen peroxide rather than heat, because higher percentages can burn your skin (not heat-related burns, I mean chemical burns). So for that reason I'd only suggest the 3% peroxide if you're going to touch it while it's still reacting.
Squint Science thank you for answering! Since it’ll mainly be for demonstration Id prefer the 35% but I’m going to use extra precaution. Do you have any tips for clean up if there is still unreacted hydrogen peroxide?
@@lisetdelatorre1974 Gotcha. The biggest part of cleanup is dealing with the iodide, which will stain everything it touches a yellow-brown color. You'll want to wear gloves (both for the hydrogen peroxide and iodide). I would recommend doing the demo on a tarp. After the demo you can wrap everything you used in the tarp and then spray it all off later. I would also have an oxidizing cleaner on hand in case you stain something (not sure where you live, but I use OxiClean spray). Have fun!
I would just dilute it with a lot of water/hose and then it should be safe. The H2O2 will decompose over time, the iodide solution can be sopped up and thrown away.

If you’re using iodide and 35% H202, do you mix them together (no water) or the iodide with the dish soap and then H202? Or what?

I see a reply below. When does it become safe to touch the foam? How should it be disposed of?
I would just dilute it with a lot of water/hose and then it should be safe. The H2O2 will decompose over time, the iodide solution can be sopped up and thrown away.
