A solid 3mm metal rod can slide (almost) effortlessly through the block. How can that be?
The mechanism for this puzzle is related to the ancient Heron's Horse
, where the magician slices a sword through the neck of a horse state without the head falling off. However, whereas Heron's mechanism
(see page 109) uses rotors, Oskar's mechanism features meshing gears. The result is a less friction and a smoother cut.
