Anyone ever microwaved grapes? Cut them in half leaving a small bit of skin connecting the two halves. Fold it out, dry the bottom (i.e. what used to be the inside), place in the microwave with the two halves sticking up like a pair of boobs. You'll only need to microwave for a few seconds before seeing the effects. Stop when they start smoking because they stink and it leaves caramelised grape on the microwave plate which is a bitch to clean off... Other than that it's quite harmless and fun.
