Safety Warning... alcohol can explode in a microwave

 Maybe only I would do something as silly as this, but anyway. I was trying to boil off the 30% alcohol from some vanilla extract (don't tolerate even small amounts of alcohol and what I was using it for wasn't to be cooked). Put about a tbs. in a pyrex shot glass in the microwave for abt 10 sec. Bubbled a little, but still smelled strongly of alcohol. So I put it back for a few more sec. and POW!  Loud explosion. The alcohol literally exploded and most of the liquid simply disappeared, the rest forming a fine mist on the inside of the microwave. The glass didn't even break, and there was no damage, but it was kind of shocking. Won't do that again.
