What's Going On?:
After about 20 seconds, the marshmallows start to puff up until they are 4 times their original size.
Marshmallows are made of sugar and water wrapped around lots and lots of air bubbles.
When you microwave marshmallows, the water heats up, which heats the sugar and the air. The air expands, and since the
walls of the marshmallow are warm too, they're flexible--- so the marshmallow puffs up. When it cools the air bubblesshrink
and the sugar gets hard.
