: Liquid oxidisers (Solids won't do for napalm) are quite hard to use because
: many oxidisers are either based on a salt (eg. potassium chlorate) or burn
: at a dangerous rate, which may cause an explosion. However a vacuum would
: only be a few degrees in temperature, at which point oxygen would
: certainly be liquefied or even solidified - but the vacuum temperature
: would make it extreeeeeemely difficult to get the fuel to a temperature
: whereupon it would ignite. Perhaps some air would be trapped in the
: flamer, which would allow it to burn for a little while in a vacuum, but
: unless it was by design, it would not be a useful amount.
Or you could be in a vacuum somewhere hot. You never know.
