The Hanayama Valve cast puzzle is a four-piece brain teaser that looks like a faucet handle but packs a lot more surprises. A metal ring can freely turn within the "valve", but two internal hemispheres make disassembly a challenge. Can you masterfully separate the parts? And if so, can you then join them all back together to restore the puzzle to its original state? It's like having two brain teasers in one!
