This fast and fun-filled game is based on the principle of what goes up must come down! Use the mouse to control your tennis racket and bounce a number of different balls safely across the screen into the swimming pool.
As one of our recent Flash Activities showed, a bouncy ball is a bit like a spring; when it bounces, it gets a bit squished as it hits the ground. If you had a high-speed camera and clicked at the exact moment the ball hit the ground you would see that the ball is a bit flattened at that place; it then springs back to its original shape as it comes up again.
