The Heath Robinson Club has been working on small-scale indoor contraptions all year and have put many of the ideas developed into the grand contraption outside the science block. Almost all the parts are made from recycled materials. The girls have added some beautiful decorations, including the now-famous St. Helen’s girl on the top, who is still holding and waving the flag she was given at the Jubilee celebration.
The water-powered wheel lifts the belt of buckets with balls balanced on them up to the top and then drops them into a basket which leads on to a series of ramps which act as a counting machine. Each time nine balls fill a ramp, the tenth one tips it sideways so that nine fall into a basket, triggering various bells and the tenth drops into the ramp below. When the 1000th ball arrives, all three ramps tip and a battery of party poppers are set off simultaneously, ending with a BANG!
