First described in 1882 by the German mathematician Felix Klein, a Klein Bottle is an example of a non-orientable surface.
Tim has examples of a regular Klein Bottle in his collection, and he also has more unusual examples. From a Klein Bottle on the stem of a wine glass (hence wine klein) to examples made of cardboard, to a knitted Klein Bottle in the form of a hat!
