For your elephant toothpaste experiment to work fully, I have figured out that your warm water and dry yeast mixture has to be the same thickness/consistency as over the counter cough syrup.
***** You can get 3% and 6% from a drug or grocery store. Possibly even Walmart. We found a higher concentration at a natural foods store but you need to be extremely careful with anything higher than 6%.
i tried to dilute the 50% hydrogen peroxide with water but it still didn't work i don't now what I'm doing wrong. but how much water should use with the hydrogen peroxide 50%.should it be like 50/50 or something else ?
+fabio kurniawan Try diluting it to a quarter of it's concentration. So 1 part Hydrogen peroxide and 3 parts water and try again. If that doesn't work I will give you more exact numbers.
ok i just tried it. this time it gives a bit of foam but only like 2 cm above the mixture .was it because i didn't use enough soap or to much yeast or is it because of the mixture?
+fabio kurniawan I know you commented that you got it working but here are some tips for others who may have the same problem. - Check the expiry on the yeast - Check how old the hydrogen peroxide is, the newer the better - Follow the directions on the container of yeast to properly activate it. - We found that hydrogen peroxide concentrations over around 12-15% would be too strong for the yeast. But if someone gets higher concentrations to work let us know.
thank you for this wonderful video I really appreciate the explanation. I took an hour searching for the elephant toothpaste video with an explanation and I took a view of this video but and I was so delighted that I finally found a video that was perfect for my science expo thank you so much.
+Jose Suba It can be in any container. If you use a large bottle like that you need to use large amounts of the ingredients. you could do it in a water glass or even a 600ml pop bottle and probably get good results.
Jose Suba Hydrogen peroxide can stay in a container for a long while. If you are wanting to show this in school or at a fair, I would suggest measuring out both th hydrogen peroxide and water out and mixing them before you do the experiment but it shouldn't harm it to be in a sealed container. Just mix extra together because the hydrogen peroxide will break down. Also the foam will dissipate so I wouldn't' take that in a container.
Can you use food grade hydrogen peroxide, and will it work if I do 20% hydrogen peroxide, please reply soon, because I am doing this for my science project and I need to know as soon as possible, thanks.
+Shadan Aj In our experience the 20% killed the yeast. We had to dilute it to the amounts listed in our video. If you can get it to work with higher levels let us know how because we would love to try.
Just go to any store and ask for dry yeast mix it with warm water to activate the chemicals Dry yeast is usually used to make baked goods like bread cake cookies rise
+fabio kurniawan You can try it but in this particular recipe I think 50% hydrogen peroxide would be too strong for the yeast. You can always dilute/water it down to a lower concentration to do this experiment. If you try it and it works please let us know.
+fabio kurniawan It's great to hear that it worked. You're very welcome for the help, that is what we are here for. A few tips when doing this experiment are check the expiry date on the yeast, check how old the hydrogen peroxide is and make sure to follow instructions on how to activate the yeast. Thank you for coming to us with your question. *Digital High Five*
Guys this is old but I really need you guys to answer I'm 11 years old and I really want to do well kinda already said I'm doing this for a science,experiment in school I was wondering two things is liquid peroxide the same thing and two are the fumes horrible and will they get trapped in the class thanks ~lilly
lilly bee Hi lilly, I am not 100% sure if liquid peroxide is the same as hydrogen peroxide. I think it is but the best way to tell is to check the ingredients or the fine print on the bottle and see if the chemical listed in it is hydrogen peroxide or something else. As for your second question the gases released from this experiment are not hazardous because the gas product is oxygen. I would caution that you don't smell the hydrogen peroxide directly as it can cause irritation to the lungs and throat but as long as you don't smell it directly it's fine to be in a classroom. One last thing, when handling hydrogen peroxide always use gloves, goggles and an apron or lab coat and make sure to replace the lid between uses.
lilly bee Normal clothes and glasses should be fine, just be careful not to splash the hydrogen peroxide. Also make sure that if you're using a highly concentrated solution of hydrogen peroxide that you wear clothes that cover your skin and don't wear sandals or open toed shoes, just in case you spill.
hum ok i see the point its really just the hydrogen paroxide that's dangerous and once again sorry for being so courious but how do you clean it up and is it safe to touch if you used 9 ./. hydrogen once again sorry for asking so many questions
lilly bee Lilly you don't ever have to apologize for being curious and asking us questions. The best scientists in the world ask tons of questions and are curious about everything. We are here to help you learn and asking questions is an important part to learning. If you use the ingredients in our video then the final foamy product of this reaction isn't dangerous, just don't get it in your mouth or eyes. You can clean it up with warm water and pour it down the sink, since most of it is soap bubbles and water. The elephant toothpaste we create in this episode shouldn't get too hot, you should be able to touch but be cautious and it may be good to test it with a thermometer first. As far as the clean up of hydrogen peroxide, use paper towel and rubber gloves, wipe it up and toss out the towels. I am not sure if you should touch 9% hydrogen peroxide as a liquid, I would check the bottle for any safety information and precautions. If it's the peroxide from the first aid section of a drug store then it shouldn't be dangerous to touch, but again check the label to be sure.
The Sci Guys True. You guys do a really nice job of explaining the science in your experiments! The elephant toothpaste was popular, but not as popular as the flash paper. Fire!!!
+Aria Pervin Umm I am not sure why. I need a little more information than that. Maybe check to see if your yeast is expired or maybe your hydrogen peroxide is under or over concentrated. Did you activate the yeast in warm water?
Guys- I Love this stuff... Can you help me with a viscosity dilemma? There is a product I want to acquire in bulk for classroom and retail use, but I do not want to make the mistake of ordering the wrong product and being stuck with gallons. I am looking to find out what viscosity a silicone oil should be to pass through a pump spray bottle. Lifespan sells a product in a 4 oz spray bottle that is perfect for our use and if I can find out the viscosity, I can acquire the product from a better source in bulk. Lifespan is not helpful in this as they want to market their own maintenance product. They do not provide a material data sheet for their product. Just a helpful push, a hint or even a nod.... PEACE
Brian David Well I am not sure how we can help here. I thought that companies had to supply WHIMIS sheets for all products. You could always google the chemicals to find out more information on them, you may be able to find the specific information that way.
+The Daedric Dovahkiin Yes we were able to touch the foam. We always recommend that if you are unsure to test the temperature with a thermometer before touching it.
This was a great explanation! I love that you include the formulas and the elements! Thanks!
Is it okay to dissolve the yeast with not warm water?
For your elephant toothpaste experiment to work fully, I have figured out that your warm water and dry yeast mixture has to be the same thickness/consistency as over the counter cough syrup.
Is it safe for children to play with this foam/elephant toothpaste after it cools down?
Umm from where can you get hydrogen peroxide?
***** You can get 3% and 6% from a drug or grocery store. Possibly even Walmart. We found a higher concentration at a natural foods store but you need to be extremely careful with anything higher than 6%.
How did you make a 12% solution from 3%?
They didn't. You have to buy it seperaretly
i tried to dilute the 50% hydrogen peroxide with water but it still didn't work i don't now what I'm doing wrong. but how much water should use with the hydrogen peroxide 50%.should it be like 50/50 or something else ?
+fabio kurniawan Try diluting it to a quarter of it's concentration. So 1 part Hydrogen peroxide and 3 parts water and try again. If that doesn't work I will give you more exact numbers.
ok thankyou
how long does it take to activate the yeast
De Indiaaan Only a few minutes. Check the container of yeast for specifics.
ok i just tried it. this time it gives a bit of foam but only like 2 cm above the mixture .was it because i didn't use enough soap or to much yeast or is it because of the mixture?
+fabio kurniawan I know you commented that you got it working but here are some tips for others who may have the same problem.

- Follow the directions on the container of yeast to properly activate it.
- We found that hydrogen peroxide concentrations over around 12-15% would be too strong for the yeast. But if someone gets higher concentrations to work let us know.
can we use normal water to make yeast paste
What was the temp?
Uhmm can this be the same if you add the yeast without actually dissolving it.
Em....may I know will this experiment works better with Potassium Iodine and what is the difference between them?
+music ! It will produce more foam and it will be much warmer. We wanted to do it the first time with as safe and common materials as possible.
The Sci Guys Can you grow your own bacteria easily?
can you touch the foam if you use 6% hydrogen peroxide?
The Daedric Dovahkiin NO!!!!
wow that was late but I used gloves in my Expirement last year so
Thank you! It's hard to find a proper explanatory elephant toothpaste experiment video!
You guys did great!
Empress Kuzco Thanks!!
thank you for this wonderful video I really appreciate the explanation. I took an hour searching for the elephant toothpaste video with an explanation and I took a view of this video but and I was so delighted that I finally found a video that was perfect for my science expo thank you so much.
Than you so much I won in my chemistry competition from you
I'm doing this for a science fair 👍
Annalie Herrera I know this a year late but I hope u did well
Where can I buy 6% hydrogen peroxide
At the store
Amazon
what is the science behind coke and mentos
Could I find hydrogen peroxide in a pharmacy?
+Shadan Aj Yup :)
I saw these in school and now I just love watching them and recreating them at home
does it really need to be a beaker can it be a 1.5L water bottle?
+Jose Suba It can be in any container. If you use a large bottle like that you need to use large amounts of the ingredients. you could do it in a water glass or even a 600ml pop bottle and probably get good results.
+The Sci Guys can you leave the hydrogen poroxide mixture for hours in a container
Jose Suba Hydrogen peroxide can stay in a container for a long while. If you are wanting to show this in school or at a fair, I would suggest measuring out both th hydrogen peroxide and water out and mixing them before you do the experiment but it shouldn't harm it to be in a sealed container.

Thank you, and can I use food grane hydrogen peroxide?
very helpful... thanks Sir
what do you mean bye dry yeast?
Dry yeast is yeast that you have to activate with warm water.
Just go to any store and ask for dry yeast mix it with warm water to activate the chemicals
Dry yeast is usually used to make baked goods like bread cake cookies rise
ora le yeast is in bread
ora le yeast
Is this covalent bonding?
I read somewhere to use 12% hydrogen peroxide. I assume this would give a more rapid reaction but would this still be safe for me to do with students?
+Tyler Troisi It should be fine but as always wear gloves, goggles and an apron or lab coat.
can i use 50% hydrogen peroxide concentration ?
+fabio kurniawan You can try it but in this particular recipe I think 50% hydrogen peroxide would be too strong for the yeast. You can always dilute/water it down to a lower concentration to do this experiment. If you try it and it works please let us know.
thank you!
Thank You :)
i enjoyed this episode
Sir the way you explain the things is very good and can you please upload drain cleaner and aluminium foil reaction
im so sorry i just tried it again and it worked thank you so much for answering my questions it means a lot to me thank you

i dont exactly have a coat or glasses so will regular glasses work and i if wear regular close they might just get dirty right ??? thanks

can I use hydrogen peroxide 30% cream. that's all they have at beauty salon.
+LizettenGus Chavez you can but you need to dilute it. Just to a little math to figure out how much water to add to lower the concentration.
is this exothermic or endothermic
It's an exothermic reaction 🙂
Absolutely amazing video, helped my science project drastically
That was great!!! We'll be doing this at home. Having the science behind it explained so well is very helpful. Thank you!
Just gonna say some advice to get more viewers and subscribers.
Put background music.
Adding lively intros.
Adding text.
Thanks so much it helped alot :)!
Tommy Kalfopoulos You're very welcome!! Thanks for watching.
COOOOL!
Hellooooo
which chemical gas law is used in this demonstration?
Thank you for your video! I'll be using it in our homeschooling science class this coming Friday!
any way to make it without hot water not nessary but it would be useful
This is actually awesome my science fair is coming up I am gonna make it as my science fair experiment
Hana Harraz Good luck!! We would love to see a photo or video of you and your experiment on our facebook group!!
Cool
this is awesome and I'm going to try this for my science extra credit! I'll defiantly give you guys credit for the idea(:
+aidan b That is awesome!! Let us know how it goes.
It worked perfectly and I had a lot of fun presenting it in science!
aidan b That is great!! Congrats. *Digital High Five*
Cool, but... "Tempurature"?
Stephen Abbott oops did we have a typo? well it's not the end of the world. We're only human after all.
The Sci Guys Yep. 4:03 and 4:10. The coolness outweighs the typo, though. I did this one for my son's birthday party earlier this year. :D
Stephen Abbott That is a sweet birthday party!! Well at least the typo didn't make the science wrong :)
The Sci Guys True. You guys do a really nice job of explaining the science in your experiments! The elephant toothpaste was popular, but not as popular as the flash paper. Fire!!!
Stephen Abbott Fire is always a crowd pleaser. I love doing the sparklers underwater experiment for that reason.
It didn't even work at all why!!!!
+Aria Pervin Umm I am not sure why. I need a little more information than that. Maybe check to see if your yeast is expired or maybe your hydrogen peroxide is under or over concentrated. Did you activate the yeast in warm water?
Aria Pervin add more yeast
wooooooooooooooooooooooooooooooooooooow
2019 anyone?!!!
we tried it and it was fun
Dry yeast yeast is in bread
+Tiger Dalek yup, yeast is in bread
just watch one elephant toothpaste becomes illegal

can you touch the foam if you use 6% hydrogen peroxide?
+The Daedric Dovahkiin Yes we were able to touch the foam. We always recommend that if you are unsure to test the temperature with a thermometer before touching it.
