Recently we were participated at China High-Tech Fair, one of the biggest high-tech related fair in the world. We loaded with bunch of brochures about our project and carried a lot of plastic popsiles, a game called ‘Buttonhole Puzzle’.
We are absolutely sure, a lot of you, guys, stepped into this little puzzleat least once in a while, because it is literally one of the most common and easiest puzzle of all time. It is a popsicle stick with a loop of twine attached on one end.
This little puzzle has been invented by Sam Loyd (1841–1911). The puzzle is placed on a buttonhole and seems impossible to remove. This is where the term buttonholed (to get someone’s attention) came from.
But if this puzzle can be put into someone’s shirt, somehow it should be taken off too…
Please, see below the step-by-step guide for how to take it off.
