Burning Hydrogen

[5614]

i dont think that i will loose my hand doing this, im not using that much of the stuff, also, should i turn the cup up right, or leave it face down?

 

there will be hydrogen and oxygen, and i dont want it to escape, do i assume that its best just to leave it down, so none of the hydrogen can escape.

 

is this safe indoors?

i would have thought so with smallish quantities.

[YT2095]

a thin walled plastic cup is fine indoors, and keep it upside down else the H will escape and take the O2 with it.

[5614]

um, the explosion or ignition will quite likely melt the cup, what can i hold the cup with which wont hurt me, catch fire or explode!? (i dont have gauntlets)

[YT2095]

well before you light it it`s perfectly safe, so put it in a safe place 1`stly and move slowly as you don`t air turbulance to dilute your mix.

then either get a long stick with a lit match atatched to it and use that, or get someone stupid to light it for for you

 

I`m joking with the last part

[5614]

hmm, this is getting harder, i will have to put it on the concrete or something, coz the table might melt [plastic] or my wooden one might get really burnt or something [thats a proper wooden one, not an experimental one!] then i'll have to make some kinda tripod stand [i dont have a tripod] so i'll just make one outta, hmmm, something! any ideas what to make a tripod out of? then i just get a stick and light it.

 

or get someone stupid to light it for for you

i'll just go and get my brother.

I`m joking with the last part

what was that? i missed that part...

 

that bit was actually quite funny!! ROFLOL so they say!

[YT2095]

no no no, the wooden table`s just fine

 

the reaction is that fast there`s no time to burn the table, the cup will split and maybe melt a little in a few places, but not enough to make a fire on your table, trust me on that one, you`re more likely to make a burn mark with the match on the stick when you drop it after the bang during your involuntary poo session

[5614]

um, with two pages or posts, i dont really think im gonna get that much of a shock when i see this happening!

 

i spose most chemical stuff happens on wooden tables though.

[YT2095]

plenty can happen on wooden tables, but I digress

Thou shalt not have mercy upon pine tables!

or thout shalt be sparketh and vexed..... amen!

no YT, i was referring to 5614 with the hydrogen trick...my professor doing it in class was enough for me to say, hell no.

the WD-40 trick is good man, and unless your an idiot, you hold the can on a slightly upright position. so that the flame doesnt reach the can. and even if i coated the can with starting fluid, it would not touch the flame, as it stays a good 4 inches from the can at all times. hot air rises, and so do flames, dont want to get burned? stay below the flames...

[YT2095]

I`m more than au faye with how it works

[r1dermon]

ok, so lets see here....burning a gas, which expands to fill its container, whatever that is, extremely flamable, completely consumed in a firery blaze in under a second....or, a controlled flame thrower using mildly flamable oil and pressurized gas. its a tough one, but considering i can't control the expansion of a gas, i'll stick to point and spray.

I once decided to electrolyze some water, and I caught the hydrogen and oxygen in a sandwich baggie. I wasn't expecting much, so I lit it in my basement. BOOM! Really loud, more than I expected. Encouraged by this, I decided to do it again, but with a gallon baggie and do it outside. Sounded like a shotgun going off. Ah, chemistry is fun.

[jdurg]

Yeah. When you have the proper stoichiometic ratio of reactants, as you would get when you electrolyze the eventual product, the reaction proceeds at an incredible rate and with a loud result. What's even more frightening is if you have some platinum wire and put that at the end of a long stick, then put that platinum wire inside the hydrogen/oxygen mixture. It will immediately go BOOM as the platinum catalyzes the reaction.

[Gilded]

Damn, I need to go and get me some Pt-wire.

[YT2095]

an easy source would be to get one of those lighters that dont blow out in the wind, the gas type, the wire gauze is Pt wire, so if you can a few broken ones (and they do break regularly) carefully remove the wire

[5614]

my friend had a lighter where the flame was green, it had some special thingy in it, which effected the flame like that so it was green, dunno what material it was though.

[Gilded]

I had a green flame lighter. The metal thingie that made it green was used up and broke off. It seemed like copper or some mix of copper and another metal.

[5614]

would copper turn a flame green? why?

[Gilded]

I don't know, it just looked like copper.

[YT2095]

yes it would/does, it`s the higher energy state of the Cu ion, that emits the color

[5614]

so if you place a strip of Cu next to a flame, the flame will go green?

[YT2095]

into, as opposed to "next to" and make sure it isn`t a huge peice, as it`s a good heat conductor and won`t reach suficient temp to ionise any of it. a thin copper wire should be just fine

[5614]

so falme with copper wire going through the middle and the flame should go green... thats cool.
