hydrogen

i was wondering if anyone has tried using hydrogen as a fuel. i have got a mix ready to make. it is very reali highly combustible and possibly too powerful.

DO NOT DO IT HYDROGEN WILL DETONATE YOUR CHAMBER AND SEVERELY INJURE/KILL YOU

Will it? The energy per volume is about the same, and if I remember right, the deflagulation speed is about the same, so no incredible pressure spike.
... which unavoidably brings about the question "why?" - if the power is about the same, why would you bother to manufacture your own hydrogen?

well i noticed that a hydrogen ballon has a much larger, louder, and quicker boom than deodorant which is my current fuel. so i thought it could be too powerful but i was just askin if any1 had had any experience/success with it. and its a lot cheaper than deodorant. at the moment i am trying to get the right mix of butane which is realy hard to do by hand, and out of heaps of tries it has only fired once. the only spudgun i have is a mini, 25mmx200mm pvc chamber with a 6mmid steel rod for the barrel and a long reach lighter spark ignition. it shoot bouncy balls after you poke the barrel through it, potatos, carrots, bits of paper, ANYTHING.

hee, how about a hydrogen hybrid? 
wouldn't hydrogen be too expensive anyway?

hydrogen can be made by mixing caustic soda with water then adding a ball of aluminium foil into it, this can be done inside a PET bottle and have a balloon over the top to gather the hydrogen that will be produce, or have a hose running to a container with a valve on it or even directly to the gun but that would be a bad idea

is caustic soda the same as crystel drano since i mixed crystal drano with aluminum foil in a waterbottle and it broke the waterbottle without it blowing up it just like made a hole in it and when i mixed it with water it took like 2 minutes and then it blow up but the explosion was nothing like a dry ice bomb.
oh and one question if i made hydrogen in a bottle by mixing the 3 chemicals since hydrogen is one of the lightest elements wouldn't that mean that the waterbottle would end up flying away???

Wow, how old are you? Hydrogen isn't that light, It is sure as hell lighter than ait, but the bottles is a couple trillion times too heavy for the small amout of hydrogen to lift....
That is kinda the reason why it takes like 5000 balloons of helium, the second lightest element to lift up a person. So that means it would take 2500 of hydrogen....

No, darkerweb.
Lift is caused by the difference in desity between air and said gas. Therefore:
32-4 = 28 (helium)
32-2 = 30 (hydrogen)
So, it'd take 4600 hydrogen balloons... which are probobly going to be cheaper than helium.
"hydrogen isn't that light"
More like air isn't that massive - it's only about 1kg/m^3. As such, your little 2L bottle gives you about 2 grams of lift, filled with hydrogen. Now, considering that your bottle will weigh about 20-40 g, that's only a factor of about 15... not the 2,000,000,000,000 that darker web pulled out of thin air.

response: how old are you? You can't even spell air lol

OUCH!!! That was some ownage right there, lol.
Hydrogen is fun as long as you don't use it in conjuction with other fuels, remember all that hydrogen is a fuel and OXIDIZER.

Hydrogen is not an oxidizer.
Do what the nice doctor said, and take your pills.

Not an oxidizer? Remind me to slap my chem teacher, and then myself for payin attention
And I don't like takin my pills, they make me feel.... happy. Blech.

Some of the stuff I do is a little dangerous ,but this hydrogen thing is one I believe I would stay away from.javascriptemoticon(':lol:')
