New action and sound parts open up many possibilities for even more exciting courses. While they race downwards, the steel balls let the new sound tubes create melodic tones. The rotary funnel offers a completely new way of bringing the balls onto the next rail. The balls also shoot and fly down the obstacle course through narrow 90 Degree curves and a cross-over. On arriving at the bottom, the manual chain lift brings the balls back up to the top again. The new Dynamic M construction set is ideal for making three exciting obstacle courses together with a dexterity game. Parts include a rotary funnel, 3x sound tubes, cross-over, 5x 90 Degree curves, magnet holder, 8x balls, 4x flex-rails 90, 14x flex-rails 180. Ideal accessories: Motor Set XS, Sound+Lights, LED Set, Accu Set, Power Set.
