A LITTLE PROJECT WITH EXPANDED AIR

MUST BE DONE WITH ADULT SUPERVISION

This is a little project to see one result of heating the air inside a container.

Place the open end of an empty bottle under water. Heat the bottle with a flame, or pour fairly hot water over the bottle.

You will see air bubbles coming out of the bottle. The air in the bottle expands and some of the air inside the bottle is pushed out, because there isn't room for all of it now that the molecules have expanded.
