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.
Unlike metal springs usually hidden in gearboxes for safety concerns, this plastic spring is safe enough to be completely exposed, even with its highest running speed, giving kids a great opportunity to explore this fascinating clockwork mechanism.
This kit can be reassembled into 3 different styles:
Spring Car - wind-up tightly and then release. The car will run at full speed for up to 14 metres. Show your friends how fast it can go!
Spring Robot - the spiral spring works with high-speed escapement, providing the robot steady power to walk 50 centimetres. Waddling around with his quirky face, you will find him the funniest and most hilarious buddy ever!
Spring Timer - the spiral spring works with low speed escapement, performing as a 6 minute countdown timer with ticking sound. Time yourself doing your favourite things. This helpful timer won't let you forget to have some fun!
This innovative science kit is fun to build and environmentally-friendly.
No motor, batteries or screws required - it is all powered by the plastic spring.
The only thing you will need is a diagonal cutter to help you build the entire piece.
