Atomic Instant Worms

The only thing better than mixing up a batch of our ooey, gooey, Insta-Worms is making a batch of eerie, glowing “Atomic” Insta-Worms! We’ve added a special dye to our best-selling Worm Goo to make slimy worms that glow brightly under black light. Just mix the Worm Activator with water, squirt in the Worm Goo, turn on a black light and wait for the oohs and ahhs to begin. The Atomic Worm Goo looks like liquid light when it touches the Activator solution. Kids and adults, alike, will be mesmerized by this delightfully gooey science adventure that is perfect for Halloween, but great anytime of year! Recommended for children ages 6 and up. You can purchase more Mini Black Lights on our site, or our large black light.

You get enough materials to make about 50 meters (160 ft) of Worms!

What's Included?
  • 1-Liter of Atomic Worm Goo Solution
  • 60 Grams of Worm Activator
  • 1 small squirt bottle
  • 1 Blue measuring scoop
  • 1 Mini Black Light
What Does It Teach?

Atomic Insta-Worms is a great way to introduce students to the chemistry behind polymers. Worm Goo is a long chain of molecules called a polymer. When the Worm Goo comes in contact with the Activator, the goo immediately changes from a liquid to a solid! That’s because the Activator acts a cross-linking solution that links the long strands of polymers in the goo together. 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

Don't keep it too long! Review by Mom

I purchased a large kit of the insta-worms. But we let the chemicals sit for months, and when we mixed them, we just made a cloudy fluid. I'm sure this is a great kit, just don't wait too long to use it!

You're right! A lot of chemicals have a finite shelf life. Try this, though. Give the Worm Goo a decent shaking and try it again. And remember, liquid chemicals are best to be kept in a mild, dry place. Thanks for the feedback and keep experimenting!

Cool gooey worms Review by mom of 3 girls

Used them for a Mad science room in my daughter's elementary school haunted house.
Tried it first in a test tube which did not produce worms, worked much better in a small beaker and really had to swirl the atomic goo as you add it to the activation solution. pretty cool with a big black light. The kids LOVED touching them and they did become harder if left longer in the solution. (Posted on 2/15/13)

Fun with glowy worms! Review by Kim Walker

The Louisiana Children's Discovery Center had a great time at our "Super Science After Hours" event and these Atomic Worms helped make it a huge hit! Kids were amazed with them and had tons of questions! (Posted on 12/23/12)

Insta-Worm Hit! Review by Sharon

I am letting you know that the Insta-Worms were a great success for the 4-H project that we presented for our local Duck Days in Lake Crystal, MN. The 4-H Butternut Boosters relied on your services and delivered a fun, and exciting project for our club to present to the community. Thank you for your wonderful exploration into science, that makes science fun! You're Da' Bomb! (Posted on 12/1/12)

Great! Review by Marcia Ostendorff

Worked beautifully. Good example of a chemical reaction. The worms actually feel cold for quite a while after being removed from the solution. Works if you squeeze the worm goo into a jar of pickles, too! Take a few pickles out so there is room to see the worms with the black light.
Nice and disgusting! Brought choruses of "That's gross" from the kids! (Posted on 11/10/12)

Atomic Worms Review by Steven F. Christensen

I have now incorporated Atomic Worms with my Halloween demo day. I also use the Dry Ice Bubble Machine - it is a big hit in my 9th grade Physical Science classroom!!! (Posted on 10/27/12)
