Our Pin Wheel Swicherz were designed by Boeing Airecraft and placed on small spy planes during reconnaissance missions to Bula Bula and Guam in the late 1990's. With a tiny, recharging engine actually built into the base, three pinwheels could power a spy plane thousands of miles. We've stolen this technology for our Pin Wheel Swicherz to increase the speed and jumping ability of those in Action Sports. Just slap it on your board, bike or boat and you'll see. It's a miracle. It really is. - Comes packaged on a J-Card.
