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!
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.
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
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.
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!
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.
mannn i have been lokking for the one vid that can show me how to do it FINALLY havent tried it yet but cant wait. i was looking for it for about 2 days because 3 days ago my science teacherlet all da student do the extothermixc one in class n we got to keep it SO MUCH FUNNN!!!!!! i jst wanted to do ut again noe i finaly get the chance to !!!!
we've tried to do this on my elective classes, but the reaction was not fast enough... it is ok to use only yeast, or is there some other catalyst to be used?? :)
Could anyone tell me wich catalyst there's being used for the last, more "explosive" experiment? I really need to know, as I'm gonna use it in a science project at school, and need a little more shock-effect than a little bit overflow of foam. Answers is HIGHLY appreciated, thanks in advance.
"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!
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.
"can't do at home."
Challenge Accepted
Great to hear Alyssa, and thanks for posting your video of the levitating orb on your RUclips channel - it worked great for you!
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.
I have a plus in our science project! Thanks Science Bob.
Your videos are actually REALLY REALLY cool. Keep making these videos please :)
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
now thaaaaat is science!
This is why I like Science.
this guy is the only person who does real good science on u tube
its AMAZING!! LOV THE SECOND PART!
This was really fun to watch! :)
We are learning about exo and endothermic reactions in my class right now!
I have a question:
"if I wanted more foam, could I just put more hydrogen pentoxide in?"
Why are ur videos so addicting? :D
"Look at that, that's good television right there."
That's awesome Bob
ScienceBob is great! better than cable television.

tis why they use it as an oxidizer in rocket fuel =P

"This you can't do at home"
Pfffft, we'll see about that.
Elephant toothpaste :> Favorite high school experiment
The last one is amazing
its always the coolest ones i cant do at home :( this is pretty epic nonetheless :D
got me the best performer award in science fair
I think I finally found out how to make lightweight concrete.
Thanks! :)
Thanks science bob! Im going to do this for my project at my science fair! Ill make sure to tell you my grade!
His attitude reminds me of Cave Johnson, especially the "Now thats science!" part
Love his science robe
Incredibly awesome
The green one was AWSOME! It was the best! :D
I came... here to see science! And I'm not disappointed.
I love your videos they're so cool!!!
WOW THIS ISSO AWESOME!bob u r like a science geniuss!
@solarseth Hey Seth! You made great science videos. I hope you make some more!
would it work with 3% hydrogen peroxide?
"See it steaming? It's an exothermic reaction, it creates heat."
I'ma go with no, not at first.
i just wish you are my science teacher i want to do experiments like that everyday!
People should call you epic science bob

this guy is such a maverick i love him
@ScienceBob for the small one what tools you need and how many cups of it do you need, also your experiments are really cool
this is really cool!
Cool experiment bro
That is so cool. I loved the assistants reaction too.That is FUNNY!!\
Great deonstration!!
your awsome bob
Science Bob is best scientist!
@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.
I was so excited to show everybody some big overflowing experiment and now I can only do that small one
An amazing person!
NOT ENOUGH FOAM?? SURELY THIS IS MADNESS!!!
i love science even though im a bit smaller age for all this its so cool!
We saw this in my school, they got amazed :D
OMG!! I love this one!! i saw it on the Jimmy Kimmil show!!!
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.
Now that was fun science!!!
I would laugh the same way like, WEEEEEEEEEE seriously cool foam!!! xD
we did this in science-class! it was awesome irl ^^
Love the second one
Awesome Bob :D -Om Nom
Now im not crazy so I'm gona step back here while you do it XD!!!
mannn i have been lokking for the one vid that can show me how to do it FINALLY havent tried it yet but cant wait. i was looking for it for about 2 days because 3 days ago my science teacherlet all da student do the extothermixc one in class n we got to keep it SO MUCH FUNNN!!!!!! i jst wanted to do ut again noe i finaly get the chance to !!!!
And this is how Dr. Sheldon Cooper came out with this haha
Good job bob
This is awesome.
Shockingly explosive!!
we've tried to do this on my elective classes, but the reaction was not fast enough... it is ok to use only yeast, or is there some other catalyst to be used?? :)
so the lastone can`t be done at home? why? is it toxic,? or is it because of the mess :).. could it be done by carefull kids at school?
thanks
god dang bob youre awsome
You can add NaI or KI either as a solid (powder/crystalline) or as a saturated solution (dissolved in water).
I was amazed even before the experiment that the lady stirred the yeast/water with an upside down spoon
We always look in in the sciencebob web with miss Jane
Now THAT is science!
Reminds me of edward norton
I am going to every one of them. I love this videos!
Could anyone tell me wich catalyst there's being used for the last, more "explosive" experiment? I really need to know, as I'm gonna use it in a science project at school, and need a little more shock-effect than a little bit overflow of foam. Answers is HIGHLY appreciated, thanks in advance.
@ScienceBob Your telling me all the foam is filled with oxygen? That would make my day. Since it would be highly explosive. :)
this guy can become a real magician!
Now THAT is science!!
@courtkneepee yeah... the shot up to the ceiling was a nice effect.
Now keep your eye on the giant flask.
thanks Mr. Bob, i got 97% in my experiment but i messed up the table and fill it with foam.
@ScienceBob I just noticed that you used the same brands as in the Scientific Tuesdays Video! :D
"Now thats is science!"
So cool wish I had all tht materials.
it's yeast and hydrogen peroxide
i will use this idea if my teacher ever asks us to do a volcano project ^_^
So freakin cool!
@chbort Glad to help. Let us know how it goes!
basically what this is its really fast decompositions of hydrogen peroxide but with added soap to make the foam
science bob you dah man
its AMAZING!!
wht would happen if you where to seal the top of the bottle? would it exploded or simply die out after a while?
is the smallest one okay to touch? or do you have to clean it with gloves
