Powerball Neon Pro

The Powerball (£14.99) is a hand gyroscope that spins as you rotate your wrist.  The faster you rotate your wrist, the faster the internal rotor spins, creating a numbing inertia that strengthens your wrists and arms.  Beneficial for golfers, musicians, tennis players, squash players, basketballers and a heap of other sports boys and girls, this grown-up’s toy is seriously addictive.
