Hmm.... Liquid Oxygen and something like [ce]N2O[/ce] in a special plastic tube (Partially as fuel, partially as a container for combustion) is what rocketeers use I believe. I don't think you'll be able to get hold of liquid [ce]O2[/ce] very easily as for the [ce]N2O[/ce] it can be madequite easily. Other types include from an oxidizer such as ammonium perchlorate or ammonium nitrate and then a fule source which is nomally solid. You can use Google to find more information. Cheers, Ryan Jones
