An object the size of a billiard ball that weighs 794 g and, when turned, feels as if you were holding a camera aperture in your hand. The segments slide into one another in sync until they can be separated at a specific point.
Why it’s picked up so often
The Venn isn’t one of Craighill’s hardest puzzles, but it is one of the most satisfying. Even those who know how it works will pick it up again because the motion itself is so pleasant. It’s cold to the touch, heavy, and the pieces fit together without any wiggle.
