Blowing a pea into a bottle

The bottle is already full, air takes up the space. I blow into the bottle. The pea is pushed out by the leaving air. Wheee!

Crushing Dad's Beer Can

We tipped Dad's beer down the sink. We put a little water in it. We heated it up until lots of steam came out. We put it upside down in icy water. It got crushed by the atmosphere because there was no air in the can. Smash!

States of Matter

We put ice cubes on top of the hot stove. The ice cube went from solid to liquid to gas, because it is heated up and the particles move faster. Zoom!
