Marble races....cut swimming pool noodle in half...lay one end higher and send marbles racing down.

Marble Races with a cheap pool noodle (occupies the kids for hours.) Did this, but instead of cutting the pool noodle, the marble is small enough to fit inside the full noodle to roll down. Then can use the noodle for other things too!
