This Impossible Screw Puzzle is Mind-Numbingly Hard to Solve

By this point in your life you probably feel like you have a pretty good idea how the world works. The sun comes up in the morning, you put your pants on one leg at a time, and screw threads work in both directions.

While that last fact may seem a little out of place in this allusion, it’s still true. Lefty loosey, righty tightey.

However, one screw puzzle aims to completely turn that notion upside down. The bolt on this particular screw only ever turns clockwise, regardless of the orientation of the bolt. If you try to turn it counterclockwise, it locks in place. Take a look at the perplexing video below and see how it works too!
