Automated marble run set with ten metres of glow in the dark tubing to build the track. All parts simply clip and slot together as detailed by the thorough instructional booklet included. Once assembled, steel marbles are taken to the top of the track via the twisting lift before rolling down the glowing track, back to the bottom of the lift and repeating the run. This fun marble run is fun and educational. Construction requires skill of following clear instructions and will teach children the science of motion and gravity.
