Selling them now to help fund my puzzle buying at IPP39.I have disassembled one of these puzzles (just not this one). They are fiddly but not impossible. One of the few puzzles a standardised Puzzle Hamster could genuinely solve on it's owm. Well perhaps two or t...

Impossible object- A plastic arrow through an aluminum coke can. Cool variation on the arrow through coke bottle. From IPP 1996. Label is also mysteriously attached to the puzzle.

Klein Stein - Really cool beer mug - Liquid begins to pour into handle and inner chamber! Made by Cliff Stoll -  The real puzzle -- how to wash it properly, ha! Some moisture has remained inside after doing a test run, it seems to be slowly dissipating but not sure how long it will take to fully evaporate.
