Engineering - inspired educational toys for hands - on building​ Gecko Run Looping

Speeding headlong into marble run madness: the new Gecko Run expansion is the Loop. How much speed does the ball need to complete the stunt? At what angle is it best to start the loop? Only those who experiment become masters of the loop!
The additional track elements mean that the marble run reach is expanded, so you can cover even more tiles, doors, windows, shelves and other surfaces.
