Yes, hey guys check out my video that i have just uploaded. Then I was using my bottles and balloons to collect some H, but even after all the solution turned black I did not collect too much, just use it all on a small explosion. Chemistry is fun huh ? Any one know what else i can do with H ?




This is someone's video to make H. I never knew H was so easy to collect.

It is very hard to keep LH, but just asking that if I can get a compressor from somewhere and compress the gas, will it become liquid H? Sorry if this question is too stupid, I don't study chemistry in class and I only study from the web.

A compressor would help, but what you really need is something to drop the temperature down to a few hundred negative degrees C (melting point of hydrogen). Then pump this under pressure into some sort of container, and hermetically seal the container.
Or, you know, just ampoule it at regular pressure and temperature. :P

Oh yes, so if compress it just in a room, it will just evaporate ?

Indeed, and why stop there ─ if you've a few unused diamonds lying around gathering dust/decomposing to graphite, you could have a go at this.

H2 is difficult to store. Google it and you'll find that hydrogen can penetrate and in some cases, embrittle metal! It can't just be compressed, cooled and stored the way propane is. The hydrogen balloon is a good demo and then there isn't much else you can do with it.

7th Cav, huh?
