See how air is not just emptiness, but has volume and takes up space. Try blowing up a balloon in a bottle. Make a simple water fountain to learn about air pressure. Race a jet-propelled balloon rocket to investigate forces. Lift a pile of books with your breath. Blow up a balloon with a simple chemical reaction. You'll have a blast with balloons zooming, floating, popping, and flying all around the room!
