Great toy to teach kids without realising they are actually learning, good price and good reviews
* The motorised gear is activated with the weight of a sphere.
* Green means clockwise turn and red counter clockwise.
* The switch gear is a gear activated without a motor (magnetically actioned) only when a sphere falls and activates the switch.
* There are multiple ways to get gear action: stand alone, with a sphere on top, with 2 gears and a sphere to create different angles, gear on gear and with elektonix (electricity conductive gears).
* Requires 3 x AA batteries (not included).
* For ages 6 years and over.
