Mechanical Science Kit Mechanical toy is a miniature version of the main part of the transmission mechanism of a car. It improves its maneuverability and performance. Similar to other UGears construction kits for adults and children, this educational toy has an iconic design and it moves. Two drive wheels mounted on the same axle can rotate at a different rate and can thus cover a different distance at the same time.
