Die Penetration - Harries Magic

You show a beautiful, sparkling die, a nicely decorated square tube and a wooden tray that fits tightly in two slots on each side of the tube. You put the tray through the slots and close the tube in the middle. Take the big die and put it inside the tube on the wooden tray. Everyone can see the die all the time through the front on the tube. Now comes the magic - the die suddenly starts to penetrate the wooden tray on the magicians command, slowly and magically. After this beautiful penetration you show everything again, die, tube and tray and even better - you are ready to repeat this fantastic effect again! 9 cm x 9 cm
