The Light Up Kinetic Wheel is quite a toy to master...run the wheel along the rails to create fabulous tricks that look even more impressive as the wheel lights up. The kinetic wheel works on the principle of kinetic energy, so by simply sliding the wheel along the rail you’re generating enough kinetic energy for the wheel to power itself along the rail creating amazing tricks. Watch in amazement as it lights up to heighten the effects! Wheel: 5.5cm diameter Rail: 26cm long x 5.5cm Requires 2 x cell (AG-13) batteries (included) Suitable for 5+ years
