An experiment from the Big Book Of Boy Stuff.

We did this earlier.  It's called Grape Lightening.


Take a seedless grape.  Cut it in half, but not all the way.  Leave a skin attachment between the two halves. Remove the stem. Put the grape on a plate facing up.  Put it in the center of the microwave.  Put the microwave on high power and set it for 10-40 (we did 10) seconds.  Now turn it on and watch.  You should see sparks and maybe even electric arcs between the grape halves.  At some point, the grapes will split all the way apart.  When that happens, stop the  microwave, because nothing else will happen after that. 

It's pretty neat.  You should try it.  Luckily, grapes were on sale this week at the grocery store so we had some.
