Here's a Tenyo puzzle trick called The Perpetual Puzzle (It's available on Amazon). You start by showing a rectangle made from 5 pieces. The rectangle fits snugly in a black plastic frame.

Finally, you show an even larger seventh piece, add it to the other six to form a rectangle. It, too, fits into the frame. How is it done?
