This fun science trick is actually an awesome demonstration of air pressure.
If we asked you to blow up a balloon inside of a bottle or, better yet, fill that balloon with water, you’d probably think that it’s no problem. Think again! The Water Balloon in a Bottle experiment will show you just how powerful air pressure actually is, and you’ll get to play some fun tricks on your friends. Having fun with friends and learning along the way? It’s a hands-on science two-for-one!
