Brand new and high quality Features: Among the most popular cartoon toys, children enjoy the fun while feeling the joy brought by the animation toys. Resting on rails placed on the gyro, let the gyro slide up and down the track. Allow the gyro to roll, and at a certain speed, the gyro will emit its own colorful dazzling light. If the gyroscope's flashing function does not activate, you need to increase the wheel's rotation speed; centrifugal force will enhance the light activation. When the gyro has enough speed to be thrown to the ground, the gyro will rotate at high speed on the ground, displaying magical colorful light effects. You can catch the spinning ground wheel and continue its rapid rotation. Gyros on rollers are more fun.
