Turn science into playtime with the Safari Ltd Safariology® Energy Ball! This interactive and educational toy makes understanding the principles of electricity fun and easy. Safe to touch, the exterior contacts allow you to complete an electrical circuit using your own hands. Upon completion, you'll see red, flashing lights and hear medium- to high-pitched pulsing sounds. This energy ball offers a unique sensory experience that's both stimulating and educational. The opaque white energy ball glows red when the circuit is completed, making it even more exciting in the dark! With a diameter of 1 ½ inches, it's about the size of a golf ball, making it easy to carry around for learning and playing wherever you go. Part of the Safariology® collection, the energy ball continues Safari Ltd's tradition of creating safe, high-quality toys that educate and inspire. All of our products are non-toxic and BPA free. Let your curiosity run wild with the Safariology® Energy Ball!
