Techno-Balls 600

This amazing series of marble runs is just perfect for techno-mad lads and their dads! Hours of fun are guaranteed - an ingenious puzzle to put together, the finished kit has a truly hypnotic appeal as the powered chain drive returns the marbles again and again! For sheer size the ‘600’ set wins hands down! The 3-stage primary tower lifts the balls high into the air before they loop gracefully from tower to tower on the suspended tracks in a hypnotic aerial ballet.
