Mini glow-in-the-dark sand for bottle,garden,aquarium filling decoration (color)Glow in the Dark: Glow Sand is made of natural resins, non-toxic and waterproof, and is small enough to be used as a caulk. Perfect for filling garden paths, vases, potted plants, fish tank crevices, or creating glow-in-the-dark sand painting bottles and miniature landscape decorations.
Usage: Open the bag before using the luminous sand, spread the luminous sand evenly, and expose it to sunlight, strong light or ultraviolet light, so that each luminous sand can fully absorb energy. It glows like a dream in a dark environment.
How it works: glow-in-the-dark gravel absorbs and stores energy from a light source (sunlight, strong light, ultraviolet light, or other light source) and emits a strong light in the dark. The darker the surrounding environment, the longer the exposure to visible light, the brighter the light can be seen.
Luminous time: Luminous gravel can continue to glow for several hours after absorbing enough energy, and slowly dimmer over time until it stops glowing. Reusable to fill your yard with splendor for decades. In fact, it also emits light and consumes energy during the day. This is one of the reasons why it replenishes energy during the day but does not glow at night.
Indoor/outdoor decor: Mini glowing sand gravel is ideal for decorating yards, gardens, paths, fish tanks, vases, potted plants, and creating glowing sand art bottles and miniature landscape decorations in the dark. Or as a novelty decoration for Halloween or Christmas, DIY crafts, or just to get kids curious about glowing sand and studying how it works.
