Hold a piece of light in your hand! Boone’s Mill Trading’s patented Glow Stones® are a toy and a science experiment all in one! These colorful stones are phosphorescent, meaning they glow in the dark after being exposed to light. Glow Stones® come in a variety of assorted colors and make fascinating room décor. You’ll love playing with this scientific marvel again and again!
Glow Stones® will glow in the dark for hours after being exposed to light for just 15 minutes, as a result of phosphorescence. Phosphorescence is a process that occurs when certain materials absorb energy from the sun or some other light source and then release that energy slowly in the form of light.
Instructions: Expose Glow Stones™ to direct sunlight or a bright light for 15 minutes. Then put them into a totally dark space and be amazed to see the Glow Stones™ phosphorescing, or glowing in the dark. Glow Stones™ are non-toxic, non-radioactive and harmless. There are no harmful effects should a Glow Stone™ be put in a person’s mouth or accidentally swallowed. These particular Glow Stones™ have been tested and certified by a 3rd party laboratory and pass regulations by the U.S. Consumer Product Safety Improvement Act.
