The Cutting a Person in Half Trick

In the video Matt Parker presents the laziest cutting a person in half trick using a strip of paper. The strip of paper is used to create a Mobiüs loop which is then cut in half lengthways with surprising results. The ‘trick’ is then explained by exploring the properties of the Mobiüs loop. As a finalé Matt cuts a Mobiüs loop with three twists in half to create a loop containing a knot. The information sheets describe how to perform the trick, how the trick works and further hints and tips.
