Bigger, faster, and more spectacular! This comprehensive Fischertechnik set, with 780 pieces, gives you enough material to build the most fantastic marble runs. Use the instructions to build one of the seven models, or use your own creativity to create a new track up to 4.5 meters long! How about a halfpipe? Or a track with a loop and a funnel? Once at the bottom, the marble is automatically transported to the top by the motorized chain lift, ready for a new adventure! Ideal additions include the Power Set (item 2580618), Battery Set (item 2580619), Sound and Lights (item 2580616), LED Set (item 2580613), and all other construction sets from the Dynamic line.
