My new S2 class was intrigued with the following :
· A piece of string wrapped twice around your thumb equals a piece of string wrapped around your wrist.
· A piece of string wrapped twice around your wrist is equal to a piece of string wrapped once around your neck.
· A piece of string wrapped three times around your head is equal to a piece of string that is the same as your height.
· Your height is equal to your arm span.
So, a small project has been started to investigate if it this is true.
