When toothpicks are inserted into the sides of two marshmallow peeps which are facing each other in a microwave. When the microwave is turned on, the peeps swell and each peep's toothpick will poke the other peep. The peep that does not explode is the winner.
The peep war left my microwave sticky and covered in marshmallowy goodness.
