From the people who gave the world the Phlat Ball, a ball so flat it had to be spelt with a 'ph', comes the Phlat Ball Syclone, a spinning mesmerising disc that transforms itself into a bomb of justice.

If we're not making much in the way of sense, then do permit us to explain. This is a Frisbee that thinks it's an American football with wings. An American football that thinks it's a Frisbee. And dashed clever it is, too.

Simply begin one's chucking session in disc mode. Find a local park and ask your fellows to make space. Throw the Phlat Ball to your chum as you would a common-or-garden Frisbee. Then stand back in awe and admire its transmutative powers as the Syclone is transformed in pico-seconds into a spinning American football complete with tail-fins for added aerial stability. Golly.

But that's a mere hint of the randomness to follow. The Syclone comes with a time-delay feature, meaning that one can throw to one's heart's content with no idea when it will pop itself into its final shape. Ideal for performing all manner of jolly japes on unsuspecting chums.

The Syclone. Voted Number One Outdoor Toy by the people who have time to vote on these things, it's a veritable shapeshifting delight. It's phlat. It's phat. Trust us. It's da bomb.
