Baffling Bands

Effect: Three loops of paper are cut with surprising results.
Secret: You need three strips of paper, each about five centimetres by one metre. Glue the ends of the first strip together to form a loop. Do the same with the second strip but give one end a half turn before gluing the ends. In making the third loop give the paper one complete turn before gluing. Cut down the centre of the first loop with a pair of scissors. This will make two loops as one would expect. When the second loop is cut in the same way it forms one extra large loop and the third one produces two loops linked together.
