This is the per­fect gift for those who think they have ev­ery­thing, from sports peo­ple and mu­si­cians to com­puter users and gad­get lovers. Power­ball uses gy­ro­scopic forces to build wrist, grip and arm strength, and it fea­tures a mo­tor than can spin faster than a For­mula 1 car’s engine at over 18,000rpm, mak­ing it one of the world’s fastest self-pow­ered de­vices. The spin­ning Power­ball ro­tor can even use mag­netic in­duc­tion to power a dig­i­tal counter (which tracks how fast you’re spin­ning the ro­tor) and lights. Used as a train­ing aid for NASA as­tro­nauts in mi­cro­grav­ity, the Power­ball is a unique present idea for ab­so­lutely any­one.
