How do you make sand glow?

To make sand glow, you can mix it with phosphorescent materials, such as glow-in-the-dark powder, which absorbs light and then radiates it in the dark. Alternatively, you can use UV-reactive sand that glows under ultraviolet light. Another method involves using certain minerals, like strontium aluminate, which also exhibit glowing properties. Once treated, the sand can be exposed to light and will glow once the lights are turned off or under UV light.
