Pure oxygen is cheap and common and used in
compressed form in all oxy-acetylene welding
sets. You can get a bottle from the local
industrial gas supplier, and while you are
there MAKE SURE to ask him about all the
safety issues as pure oxygen is highly
explosive...

For some uses (car engines) they use nitrous
oxide, it is good for increasing engine power
if you can add N02 and fuel. It is much safer
than oxygen, but still can cause some big
nasty explosions. There is a web page on the net
of a person showing the remains of their car
and garage after their NO2 bottle went bang.
Very entertaining, the whole rear end of the
car and garage door are peeled back like a soft
drink can...
