can anything bad happen you spray hairspare on a liter flame. i did it and it made a big flame it was awsome.

First, it's "lighter" not "liter."

Second, spray paint works better.

Oh...and you could catch the can on fire making it blow up in your hand.

The propellant gas in hairspray is butane, the same as in cigarette lighters. First off, never spray hairspray on a lighter. Second off, never inhale the vapor from hairspray. Third off, you can thank our activist environmental friends for banning fluorocarbon propellants. For our environmental blessings, let us weep.
