Description
More of a Joke than Magic.
A short length of rope is displayed and the two ends tied together. The audience is asked if they know another name for a reef knot. (Very few people these days know the answer) You explain that another name for it is a ‘Square Knot’ and that for those up the back `This is a square knot` upon saying this the rope is held up and it is seen it is now in the form of a square.
