Sad Man demonstrates how a triangle rotates clock wise and anti-clockwise. A song describes what happens to the three vertices as a triangle is rotated. In the warm up session, the contestants have to say what happens to the different vertices of a triangle as it is rotated. The Rotation machine demonstrates what it can do on a building site. Sad Man gives the contestants a second warm up session before the final test. Back in the Great hall for the final challenge, contestants have to rotate a rectangle clockwise and anti-clockwise. The two contestants succeed at the first task but take too long over the second task so they don't win a card.
