Two Beautiful coin tubes are shown to the audience. A banknote is borrowed from a spectator and is placed in-between the tubes, making it impossible for anything to pass through. Three coins are given to the spectator. They are placed into one side of the tube. One at a time, the coins pass through the borrowed bill. Everything can be handed out for inspection.
