<< dude, if you have grapes do this:
I dunno if you need green grapes, but I know they work with them (we praticed in Video Production class at my HS with cd's and grapes in microwave 🙂)
Alright, get your grapes, and a knife. Cut the grapes with the long side being vertical, so it's taller than it is fatter. Cut the grape down the middle of it vertically, but don't cut it all the way through. Now, since you didn't cut it al the way, there should be some of the "skin" from each half connecting the two. Put the grape newly cut sides facing up, for 30 seconds in the microwave! You get sparks, small fireballs and coolness. Plus, the worst that happens is that is just smells a little, and you have some grape juice in the microwave which can be wiped off when you take the grape out 🙂 >>
I just tried that with a red grape and it didn't do anything but sputter juice...
