Spinning top that never stops

No we haven't discovered the secrets of free energy, just stumbled across the Non Stop Top, a spinning top that once set off twirls at speed until you a)decide to turn it off or b) the batteries run out.  Whilst it revolves at high speed around your desktop it also emits an impressive LED light display, beware of becoming totally mesmerised and the minutes turning into hours. £9.99 at IWOOT
