This is a great experiment to try at home. It requires a microwave oven, a candle, a toothpick and a lighter. First you put the candle (~1-2 inches in heigth) in the micorwave (remove glass plate on bottom so candle sits on metal). Put the tooth pick in the candle sticking straight up. Light the tooth pick on fire so that flames are leaping off the tip. Shut the door quickly and turn on oven full blast. There will be loud popping noises and then balls of fire will leap from the toothpock and fly around inside the microwave while making a buzzing sound like a bee. If it doesn't work at first try moving the position of the candle. You have to find the "hot spot" in the oven for it to work.
