Spirála kapesní hlavolam

Reassembling those five spiral pieces took me almost an hour the first time, and I loved every frustrating minute of it. The disassembly is the easy part, it's the rebuild that really tests your patience.

Took the five pieces apart in under a minute, but reassembling them kept me busy for two evenings. The spiral design is deceptively tricky, just when you think the pieces will slide together they lock up wrong.

I left this on my coffee table and three different friends picked it up, and none of them got the five pieces back together without help. Separating them took me maybe ten minutes, but reassembling the spiral is genuinely a puzzle of its own.
