Boyle's law is a gas law. When temperature is consistent, then the pressure and volume of a gas have an inverse relationship. This means that when you reduce one, the other will increase.
In this experiment you will test how the volume, or size, of the marshmallow changes as you adjust the amount of pressure in the container!
