The Ball of Whacks is the perfect creativity tool for innovators, artists, engineers, writers, and students. It consists of 30 magnetic design blocks that can be rearranged into endless different shapes—including the beautiful 30- sided rhombic triacontahedron. It's more versatile than a puzzle and lots more fun than a brain teaser.
