[What is a Fluorescent Stone? Fluorescent stones absorb UV light from sunlight and fluorescent lights! They then emit that light in the dark!][Try making a Fluorescent Stone glow! Place it as close to a fluorescent light or lamp as possible and wait for about 10 minutes! Turn off the lights in a completely dark room. Or, bring it into a completely dark room. The Fluorescent Stone will glow beautifully.]
[Popular Uses for Fluorescent Stones: Birthday Parties, Christmas, Valentine's Day, White Day, Anniversaries, Parties, etc., as a Surprise with Cake][How to Surprise: Pour juice into a glass that has been exposed to UV light, place it next to a cake, and turn off the lights to complete the surprise! It'll be a talking point about fluorite glasses and liven up any party. ][For a successful surprise... try the experiment at the same time as your party! The darker the surroundings, the more beautiful the glow.]
[Q&A...Q. I've been exposing it to sunlight for several days, but it still doesn't glow! A. When it stops absorbing UV light, the accumulated UV rays are released. Release begins at sunset, so the accumulated UV rays are reset by the next day. If you expose it to sunlight and then bring it to a completely dark room, it will glow beautifully. *Please test it in a room with blackout curtains.] [Q. I received my product, but it's not glowing. A. When it arrives, the product is in a cardboard box, so UV rays have not accumulated. Try exposing it to a dark place, such as a desk lamp, for a few minutes.] [Q. It doesn't glow as beautifully as in the image. A. We photograph fluorites in a completely dark environment, with blackout curtains covering all windows and turning off all fluorescent lights. If you create a similar environment, it will glow beautifully just like in the image.]
