This dazzling new breed of high-tech tops makes ordinary tops look like theyre standing still. First theres a laser light show thats a miniature version of Fourth of July fireworks, with flashing, pulsating, multi-colored LED beams. A wild soundtrack of battling intergalactic spaceships accompanies the light show. To set it off, simply attach the winder to the top of the SUPER SONIC LASER Top, twist it several times, and hit the release button. All that spinning generates energy that powers the music and lightswithout the need for batteries. For ages 4 years and up. Note: Be careful not to "over-wind" the winder: Once it has been wound to the point that it begins to resist further winding, then STOP! Over-winding may result in breaking the winder.
