Economy Bill Change by Eric Stevens

Compact, easy, and visually stunning. You WILL use this.
First published in the book Seeing Double (also available on this site), Economy is a fantastic, streamlined variation on the classic bill change. You can cleanly display a $1 bill on both sides, yet with a simple wave of the hand it visually transforms into a larger denomination! In a final twist, the bill is slowly turned over and, in that action, magically reverts back to its original $1 form.
