Hedgehog in the Cage

Hedgehog in the Cage (in Czech: Ježek v kleci) is a mechanical puzzle popular in the Czech Republic which features prominently in the "Dobrodružství v temných uličkách" (Adventures in the Dark Alleys) trilogy of adventure stories by Jaroslav Foglar. The puzzle consists of a small sphere with protruding spikes of various lengths contained within a cylinder perforated with holes of different sizes. The challenge posed by the puzzle is how to release the sphere (the hedgehog) from the cylinder (the cage). (Wikipedia).
