Dimensions - Exploring Flatland

hint section


Question:

Can a flatlander tie a knot?

Hint:

Place a piece of string between two pieces of paper. (Clear paper or transparencies work well.) Your challenge is to pass one string over the other while keeping the string in the "plane" between the two pieces of paper. Pressing the pieces of paper tightly together may help you to imagine the restrictions of the plane.
