Atomic Slime

Product Videos

The best slime on the market just got better! You won’t believe how irresistible our slime is now, with a special florescence ingredient added to create an eerie glow. In normal light, our Atomic Slime seems to glow as it is squished and stretched… put the gooey concoction under a black light and it positively shines! Just mix the cross-linker solution with our specially dyed PVA, turn off the lights and break out the black light. Watch in wonderment as this your students clamor to be the first to touch this eerie, oozing slime. This is the perfect slime for Halloween, but is sure to amaze and excite any time of year. Recommended for children ages 6 and up. You can purchase more Mini Black Lights on our site, or large black light.

You get enough materials to make 15, 2 ounce portions or 30, 1 ounce portions of Slime... with a little bit left over!

What's Included?
  • 1-liter bottle of Atomic PVA solution
  • 500 mL of cross-linker solution
  • Mini Black light
How Does It Work?

Our slime recipe is based on the classic polyvinyl alcohol (PVA) formula with sodium tetraborate as the cross-linking agent. Doesn't that sound impressive? Just rattle that off at the next cocktail party and you'll be the talk of the evening. What makes our slime formulation unlike anything else on the market is the addition of our stabilizing agents that help to reduce the growth of bacteria while preserving the stretchy, stringy, gooey properties of slime that everyone loves. Turn this ever popular science activity into a real learning experience that is filled with real fun.

Turn this ever popular science activity into a real learning experience that is filled with real fun.

All of these science secrets are made even better with the addition of our special coloring agent that fluoresces under black light. When the energy from the black light “excites” the fluorescent dye, you end up with a brightly glowing, very exciting, ooey, gooey experiment! (For the full glowing effect, you will need to purchase a large black light.)

Customer Reviews

Atomic fun!!! Review by Bobbi

My students loved this stuff! We hosted a science night for second and third graders and they could not wait to get their hands on it! The black light gave just the amount of WOW factor we wanted. The opportunities for the scientific method are endless. I will most definitely buy this product again. (Posted on 10/29/14)

Great Review by Erin Dennis

This was a lot of fun. It wasn't too messy even when dropped on the floor or smeared into clothes. Kindergarten loved it! (Posted on 4/3/13)

Atomic Gak was hit Review by Events Solution Co.

I am event planner and used the atomic gak for a 40th GhostBuster birthday party. Amazing product with very little effort to create with just shaking it. It kept the kids at the party entertained for hours especially with the glow in the dark feature. Based on I had the party lighting as Blacklights. Thank you so much for a great product.

Halloween Fun Review by CPeace

I made Atomic Slime with my daughter's Kindergarten class. The children had a great time playing with the same with the lights on. Then when I told them that this wasn't any ordinary slime but ATOMIC SLIME and we turn off the room lights and turned on the large black light their screams of THIS IS SOOOOO AWESOME made the day an even greater success!

AWESOME STUFF! Review by MargieS

I'm having a glow-in-the-dark slumber party for my 9-year-old. We tested this kit and made one portion of slime last night. It is really cool! My son LOVES it! His friends are going to LOVE it!!!! It is quite simple, too. You simply measure out the correct portion of each liquid and stir. It turns into slime like magic! Kids can touch and play with the slime! With a black light, it glows! The kit comes with a small black light key-chain, but I recommend getting a large black light, or using black light bulbs in you regular light fixtures. I bought the shaker cups from this site, but you could make this in small plastic cups and then transfer it to a zip-lock baggie for storage. We used a plastic spoon for mixing the 2 liquids. I highly recommend this product! What Fun!!!!! (Posted on 10/18/12)

Great Review by Keri

This stuff is great. I have 9 year old twins and was looking for something other than the usual party craft for Halloween. Atomic Slime has the right balance of gross and ooh aah for girls and boys. Love it! (Posted on 9/25/12)
