Rumble Tops Challenge Crate
Have you ever watched a child watch a top? Tops are mesmerizing, as they balance and move and eventually fall over. They remain one of the classic, perennially popular pleasures.
With RumbleTops, your children will invent their own tops, then battle them against others' tops. Re-engineer and repeat. Use the scientific method and physics or just trial and error. This mechanical engineering kit for kids is delightful!
