You show three colored blocks and an empty tube. You also show a flat folded screen that you open up and place on the table. Now you place the three blocks behind the screen one by one, a red, a yellow and a blue block. The red block has a hole through the middle through which a rope is strung, you take the rope out of the block and put it aside. Now you take the blocks back one by one and stack them on top of each other, first blue, then red and then yellow and cover the whole with a tube. You then thread the rope through two holes in the screen. You then snap your fingers and when you lift the tube up the red block has disappeared without a trace! Now take away the screen and the red block is strung on the rope behind the screen! You will receive everything you need, the blocks, tube, screen and the rope including online video instructions.
