Soap bubbles, ballon and marshmallows expand and then collapse when a vacuum is created in a flask and then released.
Description:
The molecular motion demonstrator (MMD) shows that as the temperature of a solid is increased, its molecules begin to slide over one another and no longer stay in a crystalline array.

Description:
Changing the volume available for "molecules" in the Molecular Motion Demonstrator (MMD) has an effect on how often the molecules hit the walls of their container, illustrating Boyle's law.
