Fischertechnik - Dynamic Looping 

With the expansion set looping, a loop point can be built, with the guidance of building instructions, and creatively integrated into many marble runs. With the mechanical track crossing, the route can be shifted so that the marbles either shoot through the loop or follow another route. With this set, avid dynamic fans can expand and enhance their own marble run with a new action element. Includes 90degree curve, high-speed flex-rail, flex-rails 90, 3x flex-rails 180, various add-on elements (angular blocks, angular girders etc.). An ideal addition to all construction sets in the dynamic line.

- Expansion set with 50 pieces

- Build a loop point with the guidance of building instructions

- Can be creatively integrated into marble run sets

- Marbles can either shoot through the loop or follow another route with a mechanical track crossing
