This cool little money box uses an optical illusion to make it appear as though it is always empty.
Now you see it. Now you don't! And you thought CDO's were a great way to make money vanish! This little bank is much more fun and fiscally responsible. Drop a coin in the top, and tricky mirrors make it appear that the box is still empty - your money has vanished! Not really, of course - no need to call in the Fed.
