Final Day: the Bells

The verdict was that the 'clapper' would be placed on a hook outside and immediately next to the bell. The bell itself would stay still on its own rigid hook, but the clapper would move and hit against it as the see-saw moves up and down. It took a couple of trials to get the bell and clapper in the right place for each see-saw. The bells are very important to our design as they add a playful element to the see-saw, and in a sense reward the users in their co-operation in working together to make the bell ring.
