buying nitrous oxide cartriges in US?

starter fluid? are you sure you arent getting petroleum ether? cause thats not the right stuff at all. there are things with the word "ether" in their name which are quite different from the ether they use for medical purposes.

if you aren't getting the right stuff, you may as well huff gasoline or rubber cement thinner.

but i'm no expert on where to get proper ether, i just know a lot of people confuse petroleum ether for it and have seen a number of start fluids and such used as sources for petroleum ether...

 

Nesta, your right in that huffing petroleum ether would be highly . . . unpleasant.

You have to find a starting fluid that lists Diethyl Ether as its main ingredient.
