How to Have Fun on an Exercise Ball

An exercise ball
A bed
A chair
A friend
A door
A cork

Just slide off

Slide on your front.

Stand on the bed and dive onto the ball and glide.

Throw a cork onto the ball and watch it bounce off.

Sit on the ball next to the door. Get a friend to push the door open and you will go flying.

Anyone got any ideas of fun things to do with an exercise ball. Ok, I'm 13 and I don't actually use it for exercising, it's for playing on.
