Going By Tube

Effect: A rolled magazine travels up and down a string. Secret: Roll a magazine into a tube and use paper clips to hold it. Double a piece of string and hook its centre on the bottom clip inside the tube. A second string is looped through the first as shown in the illustration. Pull on the strings at top and bottom and the magazine will rise up the string. Pull on the top string, relax your grip on the lower string and allow your hands to move slightly closer together and the magazine will go back down.
