Atomic Glow Concentrate

Product Videos

Concentrated Formula - Makes up to 6 gallons (23 liters) from just 4 oz. (120 mL)!

Under normal light, the Atomic Glow coloring turns the water a cool greenish-yellow color. But Atomic Glow gets its name from the color that appears when you flip on the black light. When Atomic Glow coloring is exposed to black light, the material actually glows an eerie green color that looks... well... atomic, as the kids say.

Atomic Glow coloring requires a black light to produce the eerie, greenish-yellow color seen in the picture or on Steve's online videos. That's why we include a mini LED black light along with your bottle of Atomic Glow. Worried about how far you can stretch 4 oz. (120 mL) of Atomic Glow concentrate? Don't be. With just one teaspoon of Atomic Glow added to a quart of water, you'll have all the glow you need. That means you can make 24 individual quarts (6 gallons or nearly 23 liters) of glowing liquid!

Unlike our Glow Powder or other “glow-in-the-dark” substances, Atomic Glow reacts to the energy in black light. Add just a few drops of Atomic Glow to almost any of your favorite experiments and you are ready for a the perfect Halloween Science lesson… but you don’t have to wait for Halloween, Atomic Glow will “brighten up” your science classroom any time of year! You can purchase more Mini Black Lights on our site, or our large black light. Please note: Atomic Glow will stain. Recommended for children ages 6 and up.

What's Included?
  • Atomic Glow Concentrate - 4 oz (120 mL) bottle
    • Enough Atomic Glow to make 6 gallons (23 liters) of glowing liquid
  • Mini LED black light
What Does It Teach?

This special coloring agent fluoresces under black light. When the energy from the black light “excites” the fluorescent dye, you end up with a brightly glowing, very exciting, addition to any (water-soluble) experiment! (For the full glowing effect, you will need to purchase a large black light.)

Atomic Glow Review by Chris White

Atomic Glow is fun around halloween. My preschool Class loves to watch things glow. It is nice to something that is not to spooky for halloween. Just the right amount of halloween fun. Really fun to do with jelly marbles (Posted on 1/28/13)

Made great Glowing Lava Lamps Review by Jamie

We used the atomic glow to add to our homemade lava lamps at our son's Mad Scientist birthday party. It looked cool to have some glowing particles in the lava lamps. (Posted on 12/9/12)

Gooey and Stringy Review by brenda Emmert

I think this was one of the favorites if not the favorite. They were so amazed that when added it to things they glowed. They were even making droplets of water on the table to see what would happen and putting it all over their hands. The slime was great to make with the kids. At first they thought it wouldn't work... just add the Borax... wait and see. Suddenly they were all fighting over who got to mix it up. Only problem, I ran out of glue. Pretty neat stuff!

Lots of fun Review by Sam

My eight year olds love this kit. The jelly marbles are so cool. We put some in clear water and asked unsuspecting friends to put their hands in the water. They were surprised to find it filled with jelly marbles, which feel cool. We now are in the process of watching them get smaller out of the water. (A very long kitchen counter experiment). We tried the jelly marbles in colored water too as well as with Glow. The color fizzies are fun to watch dissolve in water and color it. (Posted on 9/17/12)

Worked well. Review by Mom of 3 girls

This atomic glow worked very well with a black light. Only a little drop illuminated the water. (Posted on 8/11/12)

Great Purchase!!! Review by Matthew Drayer

Love it! Made a glow in the dark tornado bottle with it. (Posted on 8/2/12)

AWESOME STUFF! Review by MargieS

I used this recently for my son's 9-year glow-in-the-dark slumber party. We used this to make glow "lava" lamps in the Baby Soda Bottle/Test Tubes that you buy from this website. Just follow Spangler's regular lava lamp instructions, but instead of putting food coloring in the water, ad this glow liquid. It bubble really great and glowed with the black light! The kids thought it was awesome! They took the sealed tubes home with them, along with some extra alka-seltzer tablets. I also used it to make a substance I've heard called gak. It is made with white glue, water, and borax. We added this glow liquid to the water and it turned out terrific! I think you could probably add this liquid to anything and make it glow! This liquid comes with a mini black light, but it needs to be pointed directly at the glowing substance, in order to see it glow. I recommend purchasing a larger black light, so everyone can see their glowing substance. I highly recommend this stuff! (Posted on 6/23/12)

Works great Review by Eric

As advertised, put some in water and it really glows under a blacklight. Put it in the water that you use with Jelly Marbles (small beads that absorb 300 times their weight in water) and you get these great blacklight squishy balls, really fun. Note tho that if you use the color pellets that come with the Jelly Marbles, it takes away the blacklight effect. We also tried using it with Boo Bubbles, but that didn't do much.
