What other subject can do awesome experiments like this?! NONE. Thats why Science is awesome! Thanks ScienceBob for the levitating orb demo, i showed my past teacher the trick and he said it was his best demo for his class! THANKS!
we found you cause our son was in head start. we been using ideas from your page just for fun. now my daughter is doing rock candy from your site for science project.
Yes, MikoSquiz is right, that is a demonstration - see the experiment instructions on the website for ideas on how to turn the demo into a true experiment.
The shape of the flask is essential to the speed the foam comes out! Tapered to straight neck. The principle of tuned rocket exhaust, hydraulic mining, and a little tool that turns a garden hose into a pressure washer. volume forced thru a tube into one of smaller cross-section results in an increase of velocity. Proportioning of the tubes is important to minimize cavitation and turbulent flow!
Hey ScienceBob I plan on doing this big demonstration using the same approach you took at the second experiment and I like to know the ingredients you used. Thanks in advance
There are chemicals that will have similar results, but they are much more difficult to find, and they are more hazardous. I hope the experiment goes well.
@YellowDaisy0123 The chemicals or the second experiment are usually only available to chemists and teachers. Speak to a hgh school teacher about helping you with this. Have fun.
hi bob! how do you do the biggest foam? (the foam that jumped high) and it is ok to touch the foam? I will do this for an school experiment so i need information :)
@WhiteLightSonic I'm pretty sure you can. All it is dish soap bubbles filled with oxygen if I'm not mistaken. I haven't done chemistry so I'm not sure.
Not quite, yeast removes one oxygen atom from the hydrogen peroxide leaving water behind. The forming oxygen atom quickly reacts with another oxygen atom forming oxygen molecule O2. The foam is thus created since oxygen molecules get trapped in tiny soap bubbles.
You can do that second one at home. I know where to get peroxide like that. I won't say what it is or where to get it. It is very strong stuff and should not be messed with. Peroxide that strong can cause a fire without the help of a flame so do it outside and away from your house. I am not responsible if anything happens to you from using that stuff. It will burn you or blind you permanently. It is a very strong oxidizer and it will cause fires without matches or flames.
There is a pool chemical that is 36% peroxide and it is very nasty stuff. If you pour it on some paper it can catch on fire without ignition from a flame. If you get any on your skin you will not know it right away. If you even THINK you got some on you wash good with soap and water. Sometimes things like that say wash with water for 15 minutes but I think that is to be sure you got most if not all of it off and there is no guarantee that you are OK. It just helps so it does less damage (if it already has not been done). If you ever mess with things like this use them outside so you don't burn your house down accidentally. You do not need matches to cause a fire with peroxide if it is strong enough. It can start fires on its own. The bottle it comes in is sealed inside a thick plastic bag and crimped shut with a piece of heavy wire just in case any of it does spill.
***** There are some hair care products that places like Sally Beauty Supply won't sell to just anyone and they are open to the public. It is not one of snobby places that won't even let you in the door without a cosmetology license but it used to be. I know that because my mom wanted to shop in there when they required a cosmetology license but that was a long time ago.
If I've got the chemistry right here, the foam is just dish soap with oxygen bubbled through it, so it should be fine. Probably best to avoid getting it in your eyes though, in case there's any peroxide still present.
"Thats good television right there"
It sure is Mr. Bob.
back when my Mom was teacher, she used to do this in her science class... Man, I'll tell you what, that was some of the most fun I ever had!
Great to hear Alyssa, and thanks for posting your video of the levitating orb on your CZcams channel - it worked great for you!
"can't do at home."
Challenge Accepted
wow!!! thanks science bob i showed my class this experiment to my class with my science teacher and im in 6th grade thank you very much.
Science Bob I really like your experiment. Last year I did your experience at my school science fair and I won
The man is making me smile of How excited he is. He's so cute (in a teddy bear way) Lmfao.
Your videos are actually REALLY REALLY cool. Keep making these videos please :)
I have a plus in our science project! Thanks Science Bob.
this guy is the only person who does real good science on u tube
now thaaaaat is science!
"This you can't do at home"
Pfffft, we'll see about that.
I have a question:
"if I wanted more foam, could I just put more hydrogen pentoxide in?"
What other subject can do awesome experiments like this?! NONE. Thats why Science is awesome!
Thanks ScienceBob for the levitating orb demo, i showed my past teacher the trick and he said it was his best demo for his class! THANKS!
very cool sience bob i loved all foamy and stuff!
Bob, u just saved me from hours of boredom with ur videos
we found you cause our son was in head start. we been using ideas from your page just for fun. now my daughter is doing rock candy from your site for science project.
got me the best performer award in science fair
The last one is amazing
Yes, MikoSquiz is right, that is a demonstration - see the experiment instructions on the website for ideas on how to turn the demo into a true experiment.
"Look at that, that's good television right there."
@chbort Glad to help. Let us know how it goes!
His attitude reminds me of Cave Johnson, especially the "Now thats science!" part
People should call you epic science bob
It depends on your concentration of Hydrogen Peroxide if you get a weak dilute version, the reaction wont be a cool but it will be much safer.
its AMAZING!! LOV THE SECOND PART!
@Susancool334 Yes, you can wash to foam down the sink.
The shape of the flask is essential to the speed the foam comes out! Tapered to straight neck. The principle of tuned rocket exhaust, hydraulic mining, and a little tool that turns a garden hose into a pressure washer. volume forced thru a tube into one of smaller cross-section results in an increase of velocity.

That's awesome Bob
Elephant toothpaste :> Favorite high school experiment
Thanks science bob! Im going to do this for my project at my science fair! Ill make sure to tell you my grade!
Hey ScienceBob I plan on doing this big demonstration using the same approach you took at the second experiment and I like to know the ingredients you used. Thanks in advance
This was really fun to watch! :)
We are learning about exo and endothermic reactions in my class right now!
I think I finally found out how to make lightweight concrete.
Thanks! :)
Why are ur videos so addicting? :D
There are chemicals that will have similar results, but they are much more difficult to find, and they are more hazardous. I hope the experiment goes well.
basically what this is its really fast decompositions of hydrogen peroxide but with added soap to make the foam
"See it steaming? It's an exothermic reaction, it creates heat."
I'ma go with no, not at first.
I came... here to see science! And I'm not disappointed.
@solarseth Hey Seth! You made great science videos. I hope you make some more!
And this is how Dr. Sheldon Cooper came out with this haha
@BattleZone777 Yes, it becomes soapy water, and the bubbles are filled with the oxygen.
@ScienceBob for the small one what tools you need and how many cups of it do you need, also your experiments are really cool
Love his science robe
@YellowDaisy0123 The chemicals or the second experiment are usually only available to chemists and teachers. Speak to a hgh school teacher about helping you with this. Have fun.
the 100% stuff, dear god, my science teacher was crazy enough to do it, lots of foam and steam to say the least.
this guy is such a maverick i love him
Incredibly awesome
hi bob! how do you do the biggest foam? (the foam that jumped high) and it is ok to touch the foam? I will do this for an school experiment so i need information :)
I was so excited to show everybody some big overflowing experiment and now I can only do that small one
its always the coolest ones i cant do at home :( this is pretty epic nonetheless :D
I was amazed even before the experiment that the lady stirred the yeast/water with an upside down spoon
You can add NaI or KI either as a solid (powder/crystalline) or as a saturated solution (dissolved in water).
This is why I like Science.
NOT ENOUGH FOAM?? SURELY THIS IS MADNESS!!!
No.
The hydrogen peroxide is decomposed by an enzyme in the yeast, giving water and oxygen gas;
2H2O2 ---> 2H2O + O2
That it's steaming suggests that it might not be. You could be careful I guess, but you'd be risking some burns.
Reminds me of edward norton
your awsome bob
i just wish you are my science teacher i want to do experiments like that everyday!
@WhiteLightSonic I'm pretty sure you can. All it is dish soap bubbles filled with oxygen if I'm not mistaken. I haven't done chemistry so I'm not sure.
An amazing person!
Not quite, yeast removes one oxygen atom from the hydrogen peroxide leaving water behind. The forming oxygen atom quickly reacts with another oxygen atom forming oxygen molecule O2. The foam is thus created since oxygen molecules get trapped in tiny soap bubbles.
The best way to dispose of the foam is to drop a lighted match onto it and it disappears with a flash. Don't do it in your house
i will use this idea if my teacher ever asks us to do a volcano project ^_^
@Superspongelover We don't recommend touching the foam because it may still have hydrogen peroxide in it which could be dangerous.
The green one was AWSOME! It was the best! :D
would it work with 3% hydrogen peroxide?
@ScienceBob I just noticed that you used the same brands as in the Scientific Tuesdays Video! :D
Love the second one
this is really cool!
WOW THIS ISSO AWESOME!bob u r like a science geniuss!

tis why they use it as an oxidizer in rocket fuel =P
Now keep your eye on the giant flask.
This is awesome.
Would this foam go gard Can you use this type of foam to make sound proofing blocks?
ScienceBob is great! better than cable television.
how did that happend sir bob?
its cool!
Now that was fun science!!!
thanks Mr. Bob, i got 97% in my experiment but i messed up the table and fill it with foam.
Now im not crazy so I'm gona step back here while you do it XD!!!
Cool experiment bro
@Boredclub2ndgen It's actually a sodium iodide solution.
@eatmesoftly It is best to use gloves in case there is any unreacted hydrogen peroxide.
ironic how with the high concentrate of hydrogen peroxide used in this vid, the blue stains refuse to come off your lab coat...lol
is the smallest one okay to touch? or do you have to clean it with gloves
@DarkLogic5000 It is not shampoo, it is hydrogen peroxide 20 volume. Hope that helps.
Good job bob
Bill Nye the science guy has some competition
We always look in in the sciencebob web with miss Jane
If I've got the chemistry right here, the foam is just dish soap with oxygen bubbled through it, so it should be fine. Probably best to avoid getting it in your eyes though, in case there's any peroxide still present.
wht would happen if you where to seal the top of the bottle? would it exploded or simply die out after a while?
god dang bob youre awsome
OMG!! I love this one!! i saw it on the Jimmy Kimmil show!!!
What did she pour into the big flask? Was it a yeast & water solution like the other one?
@XxXzeroXxXizm Sounds like you need more dish soap or a different kind of soap.
@Skreechchannel Im guessing for hair care it is very diluted.
@ScienceBob Your telling me all the foam is filled with oxygen? That would make my day. Since it would be highly explosive. :)
@courtkneepee yeah... the shot up to the ceiling was a nice effect.
