How Do Toys Glow in the Dark?

The video explains how glow-in-the-dark items work, focusing on phosphors, photoluminescence, chemoluminescence, and radioluminescence. Phosphors absorb energy and emit visible light, used in toys with zinc sulfide and strontium aluminate. Photoluminescent toys are energized by light, while glow sticks use chemoluminescence, emitting light through chemical reactions. Radioluminescence involves radioactive elements in watches, though it's less common now. The video provides insights into the science behind these glowing items.
