Air in your lungs

For my experiment we need: a big plastic bottle, a big box and a hose.

Fill the bottle with water, close the neck of the bottle with your finger and put the bottle upside down into the box with water. Then push the hose into the bottle and blow into the hose as long as you are able without aspiration. Now you can see how much air you have in your lungs.
