PRIZE PUZZLE FOR JULY 2007

KNOTTED OR KNOT


The above eight bits of string are either knotted or not when you pull outwards on the free ends. The puzzle is to tell me YES or NO to the question "Is this a knot?" for each of the eight diagrams.

Well, as you can see, the answers are shown. I got three answers, two of them correct. They were John Bownas and Len Brett. Len won the draw. Barry Cant slipped up on number 6 but thanks to all three for having a go.
