This is the Officially Licensed Hover Football Speaker. A half-scale football floats and rotates in mid-air, making a dramatic statement of fan loyalty. A strong magnet inside the football is repelled by electromagnetic coils and rare earth magnets in its base, a powerful opposing force that causes it to levitate and slowly spin. Liven up your room with this fun addition and enjoy the music! A unique gift for avid fans and collectors, the 6" by 8" base replicates a football field with team colors and the football hovers continuously as long as the base is powered. It attaches to its upper stand magnetically when power is off. Base plugs into AC. 10 1/2" H x 7" W x 4 1/2" D. (1 1/4 lbs.) No batteries required
