For this crazy kitchen experiment you'll need:
- Microwave oven
- Adult supervision
Put marshmallows into microwave for about 30 seconds and watch them explode. Just be careful not to touch the marshmallows, because it's very hot.
How does it work?
Marshmallows, just like popcorns, have tiny water droplets trapped inside. They create tiny bubbles of moist air that when heated expand very quickly, building up pressure inside marshmallow and making them grow really big.
