Elekit MR-9115 Robo Taimi Kit

DIY science building toy

Back in the day, when there were no batteries, clocks were powered by mainsprings, which is why you had to wind them once a day. You probably wouldn't want to have to do that every day but learning about mainsprings is still an important lesson in physics and the production of power, and this is what makes the Elekit MR-9115 Robo Taimi Kit a valuable educational tool. Besides being a lot of fun to build and play with, that is!

Using the parts in the Elekit MR-9115 Robo Taimi Kit, you can build not one, not two, but three different toys: a robot, car, and timer that can count up to six minutes. Everything is powered by the use of the coiled mainspring and you can see how the tension in it gets transformed to the power that makes the robot walk, the car run, and the timer count. All you need to provide is your time – and a pair of nippers!
