Experience a new dimension of ball track action with the Vertical Cannon. This element overcomes height differences in a spectacular way. A strong magnet creates an exciting chain reaction: as soon as a ball rolls in at the lowest level, it triggers another ball that continues to roll at an impressive height. Combined with any GraviTrax starter set, the Vertical Cannon brings action to the track and playfully demonstrates the laws of physics. Game instructions in Multilangual.
