Acetone doen't burn like gasoline - much more slowly. We used a lot 
of it at one company I worked at - needed it to clean bearings we 
made.  Anyway, we used to have a lot of fun "playing" with it.  

Here is something you should NEVER try...

Soak a rag with acetone
Light it on fire
Wrap burning rag around bit in pnuematic die grinder
Pull trigger on grinder

It's amazing what if feels like standing in the middle of that 
spinning rag, being fed vast amounts of air, spinning at 30,000 RPM 
and a fire ball that goes from floor to ceiling.  It sounded like 
a "neat idea"..... just before pulling the trigger :-)  The other 
guys in the shop said it "Looked cool".
