Clementoni 19216, Science Museum Action & Reaction Lifting System Toy for Children and Adults Ages 8 Years Plus

Now the circuits of Action & Reaction are endless because, with the manual lift system, the balls start rolling again!, The kit contains a special manual “lift” to move the balls up to a higher level. The lever at the bottom of the system just needs to be pressed to send the ball upwards!, And as children play with the lift system, they will gain practical experience and learn in a fun way about how lever mechanisms and principles of force work., The expansion is compatible with all Action & Reaction kits so children can enjoy hours and hours of fun with never-ending circuits.
