Cyberchase: Bouncing the Key
Inez and Digit have the key to escape the cave, and they need to get it to Jackie and Matt in order to escape. There is a huge block of ice blocking the two groups, so they decide that bouncing the key against a wall is the only option. They get one chance to bounce the key or they can lose it, so Inez uses a drawer that Digit found to test the angle that would send the key to Jackie and Matt. During the process, they learn about how angles of reflection work.
