1. THE GYMNASTICS OF YOUR CAT (The Physics of Falling) Have you ever seen your cat fall off the couch and land like nothing happened? It looks like magic, but it is actually physics in a fur coat .

A glass full of water (to the brim), a piece of stiff cardboard (like from a cereal box), and courage.

Scientists at the University of Rochester discovered that playing action games (like platformers or racing games) for 30 minutes a day can improve your by 20%. That means you can spot a typo in your homework faster or catch a baseball that seemed impossible to reach.

The water stays inside! The cardboard doesn't fall.
