The performer’s wrists are tied to a tube with long ropes which are then held by a couple of spectators at the ends. Magically, the magician escapes in full view!
Hand the plastic tube out for examination while casually handling the two ropes. Take the tube from the spectator and twist the ropes so they can be inserted into the tube. Then pull two loops up through the holes in the tube so you can insert your wrists. A spectator now ties a large knot on top of each wrist using one end of each rope. Have two spectators hold onto the ends of the rope and at the count of three they are to pull hard. Magically the magician frees himself from the restraint as the tube goes flying into the air leaving the ends of both ropes still being held by the helpers.
