In this Gravitrax How-To-video we tackle the cool, but sometimes difficult to master the Trampoline Expansion by Ravensburger! Starting with 3 golden rules, the trampoline is explored through 5 levels, starting with the basic principles and finishing advanced! The video contains Gravitrax App codes, so you can rebuild many examples it yourself! Where the Gravitrax App does not allow for certain building techniques, one can rebuild the track using the close up video images!
