Shrink Your Money!
The Micro Bank creates an amazing optical illusion when it appears to magically miniaturize a coin passing through its incredibly narrow funnel.  The coin shrinks to a mere fraction of its original size as it passes through the funnel and drops into the tiny chamber below.  You can see just how small the coin has become through the box's window.  The tiny chamber stores and displays many coins as they shrink and pile up!  Trick your friends as they watch in amazement.  Can you figure out how this illusion works?  Solve the mystery of the shrinking coins!  Fun for all ages.  Measures 3.25" x 3.25" x 5'.
