6A10.XX Micro Bank
Reflections from flat mirrors, lenses
Coins appear to drop through a funnel that should be unable to pass the coins. The coins end up in a box, apparently shrunken.
In reality, the funnel doesn't exist, and the actual structure of the bank is cleverly obscured by mirrors. A lens (probably diverging) in front of the box makes the coins appear smaller.
