Description
U & U – Intermediate Take Apart Puzzle
U & U is a cast-metal take-apart puzzle designed by Kyoo Wong and produced by Hanayama. Two U-shaped bolts and four nuts give it the familiar appearance of a handful of hardware.
Work out how to separate the interlocked parts, then rebuild the starting arrangement. The ordinary-looking components conceal a less obvious relationship, so observation is more useful than assumptions about how standard nuts and bolts behave.
