Spinning Magnetic Orbs
Each Spinning Magnetic Orb is a pair of strong magnets mounted in a gimbal that allows them to spin while the transparent shell that houses them remains still.” You can perform a lot of tricks using the magnetic orbs: make them roll and steer them without touching them, they can spin and collide, and you can expand the tricks by using the included magnet proxies.
