Take an old fashioned glass (a stubby drinking glass). Put about two
centimeters of water in the glass (deep!). Place a 60 W light bulb
in the glass with its base immersed in the water. Place in microwave
oven. Arrange spectators around window of oven. Cook for one minute
at full power. Serves about six.

Notes:
 This is better if you have a turntable and locate the glass off center.

 It doesn't matter whether the bulb is initially burned out or not. (It
   will certainly be burned out after this treatment.

 Don't touch the bulb for three minutes after it is done. It will be hot!

 Have another bulb on hand. Even if you only have six spectators you will
   be asked for seconds.

 There's nothing magic about the ingredients above. Experiment; enjoy!
