Kids can launch into a world of fun with the redesigned VEX Robotics Catapult. This construction kit featuring more than 150 pieces is great for budding engineers who want to build, test, and launch projectiles over 20 feet. They can develop their love for physics and STEM concepts, all while letting their imagination loose when they play. Kids simply turn the dial to load the Catapult and pull the launching lever to fire away.
