Those crazy Americans have done it again. Another teen craze. Another set of world records. And another UK first from gadgetshop. Geoff here at HQ first thought they were a set of fetchingly-coloured drinks cups on a tray. But how wrong he was. For this is a fiendish challenge that will have you stacking and unstacking faster than the night shift at your local Tesco.

Your objective is simplicity itself. Simply stack and unstack a set of 12 cups in a number of pre-determined sequences in the shortest possible time. Sounds easy? The world record for the fastest-recorded speed stacking is 6.21 seconds, so the gauntlet has well and truly been thrown down to us Brits. This warp-speed athletic event for the hands enhances not only bilateral proficiency, developing more equal performance on both sides of the body, but works to improve the potential of the right side of the brain which houses awareness, focus, creativity and rhythm. Leading-edge technology in the form of a patented digital hand timer used to measure world record attempts will keep you on the straight and narrow. And, in a new sport where every nanosecond counts, it's a truly essential device.

Ready, steady... stack. Get bitten by the speed stacking bug and we promise you'll soon be hooked.
