766. 4-1/2" long, 1-3/4" diameter, two pieces of metal that were probably able to be separated long ago, but now are fused together as one.

767. Another "impossible object", the puzzle is to determine how the golf tee was inserted into the piece of wood. The lower part is drilled all the way through so the tip of the tee is resting on the gray surface. Neither piece has been cut or glued.
