I once mentioned to the young (20s) chemist brother of a good friend some
of the possible issues involved with carrying around a butane lighter.  Few
weeks later his brother told me "I heard this god-awful boom and flash and
the windows rattled like crazy -- went rushing downstairs to see what on
earth happened and met [my brother] coming in white as a ghost."  He wasn't
convinced about the lighter, so being an experimental chemist took a Bic
out in the back yard with a piece of magnesium ribbon wrapped around it,
lit the ribbon and retired to the porch to see what if anything
happened.  His expectations were exceeded...

I'm pretty sure that an A/C unit has a good deal more than a Bic
lighter...but how fast and in what direction it comes out, and whether
liquid or vapor would all affect the issue.  Maybe we should try it a few
dozen times and see if there's a pattern?
