The Best Glow-In-The-Dark Rocks

Buying Guide

Things that glow in the dark invoke curiosity from both kids and adults. How do these things glow? Why do they glow? How long will they glow for? The questions are endless, and keeping glow-in-the-dark rocks around your house or garden keeps the intrigue going for kids and adults alike.

Glow-in-the-dark rocks come in different shapes and sizes, and they can even glow in different colors, making them a fun addition to crafting projects or potted plants.

There are a number of different ways things can glow in the dark, one of which is bioluminescence. This applies to natural plants and animals that glow. Jellyfish or fireflies, for example, glow as a result of bioluminescence because they contain a special chemical that lights up.

For things that don’t contain natural bioluminescence properties, they can glow using chemiluminescence. There is a specific chemical reaction that occurs which results in the object glowing.

Toys and other objects use phosphorescence. These objects glow because they contain phosphors, which give off light after being “charged” with energy or light forms. For example, these objects soak up light during the day and then glow in the night. This is typically how glow-in-the-dark rocks work.

• When you’re looking for glow-in-the-dark rocks, you’ll need to first decide how they will be used. For example, if you’re looking for a kit for kids interested in STEM topics, opt for something interactive. You can find glow-in-the-dark rock kits where kids can use luminescent paint to decorate rocks. If kids like to showcase their rocks outdoors, then you’ll need to go with waterproof paint so that it does not wash off or fade when it’s raining. Be sure to check that everything you need is included in the kit, such as rocks, paint and brushes.
• If you’re looking for glow-in-the-dark rocks for adults as a décor item, then consider what color and size you want. Typically, glow-in-the-dark rocks are pebble-sized and come in several different glow-in-the-dark colors, such as blue, green and purple. Depending on your use, you may need to get several packages, such as if you’re covering a large surface area. For use outdoors, it’s best if the glow-in-the-dark rocks are waterproof. Also consider how long their charge time is. Usually, it will take a few hours of sunshine for the rocks to be able to emit light at night.
