An extension add on to the Starter Run, adding a loop into your run.
How much speed does the ball need to complete the loop 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.
Includes a loop, 4 adapters, tracks, track bridges, 8 nano adhesive pads, colour illustrated instructions.
Expansion for the Gecko Run Starter Set.
