Toffee, peanut butter and aluminium powder as solid fuel, nitrous oxide as oxidizer. Mind you, a glass jar wouldn't be up to the task but it is far safer than storing bottles of hydrogen peroxide. See: youtube.com/watch?v=Hqxb06LpXTI

I liked this experiment, but I was really hoping for a rocket engine I could launch a real rocket with.
Ken O (3 месяца назад)
This sort of skipped why rockets move. We cause a pressure to be present inside the rocket. This pressure pushes in all directions against the inside of the rocket and this pressure would push the rocket causing it to move, but in each direction it pushes, it also pushes in the opposite direction, so in gets balanced out & there would be no movement, except that there is one opening --So there is a single direction the pressure is pushing in, (the direction opposite the opening) which is not balanced out.

You should put it on a simple kitchen scale, so you can measure how much thrust it's generating.

You've also made a very weak thermic lance. That's a super hot flame used to cut up big chunks of metal. Carbon rods in a tube, connected to a pure high pressure O2 stream.

put this rocket on a kitchen scale that reads out grams. light it and see how much thrust you've created, if there's a measurable amount

would be neat to see more videos like this! also the 135 people who don't like this suck :(

yall got some boring rockets, I build more fun stuff in my kitchen. it aint all about flow its about fuel/oxidizer ratio and compression and jet/nozzle size and for space faring rockets one must observe tsiolkovsky

I wish we could have seen this occur on top of a scale so we could see the actual thrust produced

I was actually waiting for the burning noodle in connection with the pure oxigen to set the steel lid of the jar on fire... Steel + pure O2 + ignition source = trouble

i dont have yeast so i used some calcium carbide and water to make acetylene gas (CaC2+H2O=C2H2) and everything caught on fire

I might not understand something, but you simply burned a noodle on a jar and nothing happened

When I saw this exact same experiment on another, more obscure, youtube channel I did think it was cool and I later saw an eposide of myth busters (first one on netflix) where they made a bigger one out of candle wax but it wasn't until watching this video with all the extra explanation that I had the idea to see if I can combine the two and drill out a candle on top of a jar with perhaps some battery acid as the catalyst (would love to get my hands on a medical oxygen condenser) anyway, wish me luck as I really hope not to kill myself or burn the house down. ;-P

If it goes catastrophically wrong, don't worry, just put in your buildings elevator.

my grand kids thank you I will be trying this, they are 7

When theuy say: pure oxigen is highly reacting, what does it react with? for example would pure oxigen explode or burn if in contact with a flame? What the chemical reaction happening in the explosion?
Ivan (4 месяца назад)
make more of these experiment episodes
Anya Thurmes (4 месяца назад)
I feel that the most appropriate way to do this is with a Ball mason jar, since they also make _real_ rockets.
Joshua Hansen (4 месяца назад)
I have a sort of crazy idea for hybrid rocket that uses both solid fuel and Cassius / solid oxidizer
Dylan Crespo (4 месяца назад)
Wouldn’t the reaction between the yeast and hydrogen peroxide also create hydrogen gas?
Ron White (4 месяца назад)
That's more of a candle.

You can also make a pulse jet with a mason jar by putting a small amount of pretty volatile fuel in it (I used methanol), poking a hole in the top, and lighting it. Very noisy and more exciting but not nearly as safe, especially since it tends to break, which, you know, spills hot jet fuel near a flame. It helps to put it in a pool of water though. Advice to anyone who wants to try this, it's important to get the hole in the top as round as possible. You can probably find pictures where people suspend a metal tube inside the jar but I've never tried it.

3:18 anybody else briefly think Hank was flipping us the bird?
Dead Parroting (4 месяца назад)
The shape of the solid component's molecule should be the big influence on the structure. Making the attachment point for the oxidizer readily available would be key.
R3Testa (4 месяца назад)
Before doing this, try the noodle on the jar with the hole, but without the hydrogen peroxide and yeast. Then you can see if there's a difference between a burning noodle and this.
Tyler Peterson (4 месяца назад)
I feel like maybe a drop or two of liquid dish soap would have been beneficial, to prevent the liquid from potentially shooting through the hole. Too much of the peroxide or yeast might end up with the noodle or the floor wet.

Reminds me of the time he built a bomb in the basement with Drew.
Scott Miller (4 месяца назад)
Nice. A good addition to the experiment would be to burn a pasta without the added oxygen. Is the flame as high? Does the addition of oxygen do anything? Myth Busters tried to build a hybrid rocket using a bunch of salamis (with a hole drilled down the center) stuffed into an aluminum tube, end to end, and nitrous oxide (if my memory is correct). Didn't work. blobs of salami broke loose and clogged up the hole.
king james488 (4 месяца назад)
I'm sure happy I learned volcanoes are full of baking soda and vinegar. and that's in no way a rocket engine, you're just burning a noodle.
Salvy Gonzy (4 месяца назад)
explanation is good but your rocket example is bad very unrelated you should used sugar and stump remover
Daniel Giles (4 месяца назад)
So if you put the mason jar on a scale, you should see the wait increase, which will give you the thrust it's producing. After I wrote this I say a similar comment below. A bathroom scale would probably not be sensitive enough -- you'd need a kitchen wait scale set to grams.
martijn smit (4 месяца назад)
Okay this just gave me a terrible idea. Put the hydrogen-peroxide and yeast in a potato cannon close it off, let pressure build up for a bit. Put powdered sugar or flour in the barrel and fire at a flame. Don't do this, this is a very bad idea.
yammer5 (4 месяца назад)
This is one of those channels that I straight like even before I’ve seen the video, because it’s a guarantee that it’ll be good.

I can't believe you were in the kids space and Squeaks didn't make an appearance! 🐭
sambowman91 (4 месяца назад)
Not to be a pedant, but that's not how hybrid rockets work. Hybrids work by melting/entraining/subliming the fuel as the oxidizer is moving past, and combusting the two. The combustion moves from the center of the fuel grain out. This experiment basically just set a noodle on fire in an oxygen-rich environment.
Adam Wishneusky (4 месяца назад)
very cool demo!
Charles Davidson (4 месяца назад)
What if you added more rigatoni? More mini-thrust?
sniperammow (4 месяца назад)
My mom does not say why, she brings the mop to my face, beats me with it and then forces me to clean the mess I made.
Laura Jones (4 месяца назад)
Do this on a force plate! (weight scale) to see how much thrust it actually does generate! I'm curious now....

For anyine wondering whats the deal with Hank and Elon Musk, it went something like this: Hank: You can agree with Elon that he is a job creator and also agree that he shouldn't have clapped back to a stranger in anger when he is a billionaire with millions of very passionate followers. Elon: I think the person who attacked me on Twitter will survive somehow Hank: Oof *sad emoji face* Thats all, people in this comment section are blowing it up out of proportions.

Man all that money I spent on Estes and other brand engines and I could have been using Pasta instead.

Funny how this displays still ads while almost all similar videos from other channels can't as they are "not advertiser friendly". Oh I forgot, you have 5mio subscribers.

This was a learning experience. Thank you for the information.
Robert Cartwright (4 месяца назад)
The problem with using a kitchen scale to measure the thrust in this experiment as some have suggested is that the thrust force on the scale would be canceled out by the mass loss from the burning of the fuel and the release of the O2 from the peroxide.

I have a question for everyone in the comments who knows a lot about biology, I’m going into my señor year and want to have a bio project that involves generational breeding of aphids. Do you think 1 year is enough time to make the project results worth while. It’s about diet change and behavioral response

The reason these engines don't work is because you're using rigatoni.
