Filling a Balloon

Filling air in balloon is an interesting activity. The child may ask you to do it repeatedly by which we get tired, but, what's more than their fun and learning?

You could explain the toddler that there is air in the balloon, we cannot see air, we can only feel the air. I use a manual balloon pump to fill in the balloon and A observes the balloon as it expands with air.

Then, I also point the balloon pump to her palm so she can feel the air, she wriggles at it and asks for it again.
