Coin Tube - Aluminum
Item Number: TA7030
Two aluminum tubes are shown to the audience. A half dollar is placed between the two sections before they are screwed together. It is impossible for anything to pass through the solid coin in the middle.
Three quarters (or similar size coins) are placed into one side of the tube. One at a time, the coins pass through the half dollar and fall out the opposite side. Everything can be handed out for inspection.
