Grab a friend!
Ok, here’s the 1st puzzle I’ve seen where you can physically dual it out with a friend. First you’ll need some string. And if you’re at work, why not ask the person sitting next to you to give it a try?
Here we go:
Take 2 pieces of string and tie it around the wrists as shown below. The puzzle is for both of you to release yourselves without untying the string!
If you can solve this in your mind’s eye with pure brute force mental rotation/visualization power, then I bet you can probably score high on this brain game?
