First you build, then you battle! Punch up the "fun" in science fundamentals with the Explore Science Rumblin' Robots. With this kit, junior scientists can learn the basics of circuitry as they build their own boxing robots. Once done, family and friends can have bot-battles to see who will become king of the ring. The kit includes individual scoreboards that allow players to track their own points and a boxing ring base that doubles as a storage box.
