The Micro Bank - also known as the Incredible Coin-Shrinking Money Box - is a fantastic optical illusion.
Put a coin in the slot at the top, and the coin slides down the silver funnel, which becomes impossibly narrow at the bottom. The coin then apppears in the little box - but now the coin has shrunk to about a quarter of its normal size. No regular bank would get away with shrinking your money by 75%!
However when you want to get your money back, there is a little slot at the back, and when you slide this open, your money appears. Luckily it is now back to its original size. Phew!
The box is 8x8x12cm
