I used a empty pop bottle to demonstrate the existence of air. What is in the bottle?
I squeezed the bottle onto their faces so they could feel the air blow out.

The air can also make things move. We can see the leaves rustling on the trees and our washing swaying on the line.
We blew through a straw to make balls of cotton move around the table.
Macey figured out she could also use the empty bottle to move the cotton balls.
|Wow! Look what I can do :)|
We then made paper windmills and watched the air blow them round in the garden.
We also filled a carrier bag with air and squeezed it back out.
