Combustible gases in balloons

A demonstration of hydrogen and oxygen and their relationship to fire.

Warning do not try this without adequate safety considerations (hearing, eye and fire protection). Do not do this as a joke. The concussionary force is strong and can injure if too close.

What about Nitrus???

[goldenpizza]

@chaterbox0 You mean NitrOx aka nitrous oxide NO2.

When heated sufficiently (like a piston) N2O decomposes exothermically to N2 and O2 .If this reaction occurs in the combustion chamber of an automobile, 3 moles of gas would be produced from 2 moles, providing an extra boost to the piston, as well as liberating more heat. There is a necessity of heat (fuel) to cause this reaction. It would not work the same in a balloon.

What is the apparatus called, which you made to pop the balloon?

[goldenpizza]

@fifafreak310258 "candle on a stick" ?

@DarkGlitchX yes,, its been proven many times.

@goldenpizza The H2+O2 balloon was more powerful in the sense that it reacted more quickly, yes. Powerful in the sense that it made a louder boom, yes. But not more powerful in terms of the total energy it put out. If not for the O2 in the air, the H2 filled balloon wouldn't have reacted at all. It just reacted more slowly.

Yes, I know about H2 powered fuel cells. Note that the tanks contain pure H2, not a H2/O2 mixture, which would be extremely dangerous. They get the O2 from the air.

[goldenpizza]

@ApolloWasReal The H2 + O2 WAS more powerful. I was there. Remember, liquid fuel rockets use H2+O2 combo, not just H2. Care to guess why? Its more powerful.

Also, there is compressed Hydrogen currently being used as vehicle fuel in a few test cities (specifically Los Angeles) . The storage is sImilar to the tanks used for CNG.

[ApolloWasReal]

@DarkGlitchX The H2/O2 mixture was actually less powerful because there was less H2 in that balloon. The difference was that the hydrogen burned much more quickly since it was already thoroughly mixed with O2. The pure H2 had to mix with O2 in the atmosphere before burning so it burned more slowly. Yes, this could indeed be done in an internal combustion engine, but what's the point? H2 is difficult to store, and it has better uses than internal combustion engines, e.g., fuel cells.

[ApolloWasReal]

@goldenpizza I think maybe he meant a mixture of H2 and N2O? Although N2O won't support life, it does behave as a good oxidizer. Add the exothermic decomposition of N2O and it should create a most impressive bang.

Hahaha... that's crazy to light a H2 and O2 mixture at such close range!

0:39 the look on his face....he's like "i dk wtf elts you kids expect..."

[ThespeedyHD]

COMBUSTABLE LEMON!

[DarkGlitchX]

It seemed that the Hydrogen + Oxygen mixture was much more powerful. Could this be used in a combustion engine?

I went to a party and saw sealed ziplock bags filled with oxyigen and acedelene and dropped on an open camp fire they made a VERY loud boom. set lots of burgler and car alarms off also made a very strong shock wave.
