Explore the Science of Building Polymers by Cross-linking Long Chains Of Molecules
Now available as a classroom kit!
Steve Spangler and his team of slime-ologists created a new kind of slime that appears the instant two liquids touch. It’s called String Slime and the ingredients are safe, easy-to-use, and won’t stain your hands. This kit includes an Activity Guide with instructions to make a perfect batch of String Slime every time.
Squeeze a long stream of String Slime into the Activator Solution and you’ll get instant fun!
You won’t believe your eyes as the honey-like goo changes into a rubbery solid the second the two solutions mix. This unique polymer formulation (no Borax or PVA used here) is safe to touch and weave between your fingers. If you love the classic “slime” activity, String Slime is guaranteed to knock your socks off!
What does it teach?
The “hands-on” science factor is great for younger students while the strong science content makes the activity perfect for upper-level students and teachers. Explore the science of building polymers by cross-linking long chains of molecules. The process of making String Slime is faster and easier than the classic Slime recipe and it happens the very second the two liquids mix. It’s truly amazing!
Our Classroom Kit Includes:
This classroom version of our classic kit has materials for 24 students working in groups, including bags to store their slimy colorful strings!
How Much Does It Make?
You get enough materials to make about 98 meters (320 ft) of String Slime.
For Teachers, Parents, Grandparents, and All-Around Science Adults
We haven’t forgotten about the new STEM and STEAM initiatives in our schools, bringing Science, Technology, Engineering, (Art), and Math together to make young scientist into real thinkers! Look what your young scientists integrated into the String Slime-making activities.

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!

We have a MAD SCIENCE DAY each year at our center and this is a keeper since the first year! The children enjoy making their own worms! This hands on activity is a great classroom lesson!
The children ask each year, Are we going to make worms again? The last time we did it, we added food coloring! the children got to pick the color they wanted to make their worm!

Got this for a First Day of School science experiment. I admit I was a little worried about doing this the first day, but it was great! The students were so enthusiastic and did such a great job working together. They were thrilled that they could take their worms home with them and eager to try out some extra experiments at home with them. I heard that they went home very excited about science this year. I will DEFINITELY start the year off next year with this again!!

I bought this classroom kit and the instant snow kit for my son’s 7th birthday party. I made all kind of colors of worms and surprisingly, the girls loved them just as much as the boys if not more. The girls took a whole rainbow of colored worms home from the party. One of the parents was so impressed he asked where I bought the kits from. I was more than happy to say ‘Steve Spangler Science!’

I teach science in the homeschool community and the Insta-worms are always a big hit! I use them to talk about molecules, chemical reactions, polymers… and the kids absolutely love them! Year after year! Thanks for producing products that excite kids (and parents) about science!
