#11 The Key Player / Balloon and Balls

Key number 11 is played by this fantastic design from Hatfield Heath school, in which a balloon filled with balls is popped with a pin, sending the balls to the piano.

The children at Hatfield Heath School really understood the project and a brilliant first design session was experienced by all. The chosen design developed by Molly, a year 6 pupil, is for a ball to roll down a tube, released by popping a balloon. The ball hits a stick that rotates and pushes down on the key. Molly thought carefully about protecting the piano, and the structure needed to hold the tube in place.
