Harry helps kids to come up with ways to show that air is everywhere. The kids learn that air's all around them. The first way to prove is that creature needs air to breathe and make their bodies work. The second is that smell travels through the air. The third is that when something is falling to the ground, it pushes air out of the way so it can get to the ground, so the air being there is the reason it floats. The fourth is that when people blow air into a bottle it makes music.
