About this item

• GLOW IN THE DARK: Glow sand is made from natural resin, is non-toxic and waterproof, and the smaller sizes are suitable for use as gap fillers. Perfect for filling garden paths, vases, potted plants, fish tank gaps, or creating glow-in-the-dark sand art bottles and micro landscape decoration.
• HOW TO USE: Open the packaging bag before using the glow in the dark sand, spread the glow sand evenly and expose it to sunlight, strong light or ultraviolet light so that each glow sand can fully absorb energy. It will emit a fantastic dazzling light in a dark environment.
• HOW IT WORKS: Glow in the dark gravel can absorb and store the energy of light source (sunlight, strong light, ultraviolet or other light sources) and emit bright light in the dark. The darker the surrounding and the more exposure to visible light, the more bright glow can be seen.
• GLOWING TIME: Glow gravel can continue to glow for several hours when it absorbs enough energy, and will slowly dim as time goes by until it stops glowing. Reusable to brighten your yard for decades. In fact, it also glows during the day and consumes energy continuously. This is one of the reasons why it replenishes energy during the day but does not glow at night.
• INDOOR/OUTDOOR DECOR: Mini glow sand gravel are suitable for decorating yards, gardens, pathways, fish tanks, vases, potted plants and creating glow in the dark sand art bottles and micro landscape decoration. Or as a novelty decoration for Halloween or Christmas, DIY crafts, or just to make children curious about luminous sand and study the principles of luminescence.
