With a mini gyroscope inside, powered up by batteries and a magnet, every time you place the top into the Stunt Top paddle, the magnetic booster powers up the gyroscope to a high level of RPMs. Drop the top on any surface, and when the top begins to slow down, you can "scoop" it up into the paddle and recharge it in seconds. Will spin on either end of the top. Toss in the air, catch it, recharge it. What tricks can you come up with? Batteries included.
