Build your own working roller coaster model made of real wood! The Coaster is full of dips and turns with some engineering and physics thrown in, so once you build your coaster, you can run marbles through it.
With the crank of the handle, fire up the gears and watch as the waterwheel coaster carries the marbles up to the top and releases them down the track. This gave you the opportunity to explain gravity, gears, machines, engines and many other STEM concepts to eager learners.
This 254 piece puzzle kit contains everything you need to assemble in the package; you do not need any additional materials. Ages 14+. Takes 3-5 hours to build.
