You don't have to be a rocket scientist to unravel this cube into a snake (just twist and swivel the 27 wooden cubes to uncoil the serpent) but it certainly helps to be a genius to put it back together. This legendarily difficult brain-teasing puzzle will have you undulating in no time. If the snake starts to constrict you, just remember: The string of cubes form a Hamiltonian path through a 3×3×3 grid graph, duh! Skill and patience will be tried when turning the snake back into the original cube.
Dimensions: 2 1/3" x 2 1/3" x 2 1/3"
Object: Unravel the 27 cubes into a snake then try getting it back into the original shape.
