Ball of Whacks
The Ball of Whacks is made up of 30 magnetic blocks that can be taken apart and rearranged in endless ways. More versatile than a puzzle and lots more fun than a brain teaser, there's no wrong way to play with it. Designed by Roger von Oech, it gets your creative juices flowing. It comes as a rhombic triacontahedron, but can take as many shapes as you can imagine. 96-page illustrated guidebook provides exercises for creative brainstorming and problem-solving. Ages 8 and up.
