The Johnco - Springer - Spiral Spring Science Kit is a great product that aims to ignite a child's imagination and encourage them to think big, learn & discover. Explore the secret of clockwork mechanisms. Discover spring power! Have you ever wondered about the power source of a wind-up car or where the ticking sound of a clock comes from? The secret lies in the mainspring. Centred on the clockwork is a spiral torsion spring where you will be able to store energy by winding it tightly. Then release it to trigger the inner mechanical operation and watch your spring timer, spring car or spring bot start moving! When the spiral spring is totally untwisted, the operation then stops. The mainspring of this 3-in-1 science kit is the first one in the world made of plastic, instead of metal.
