String Slime Goo Science Kit

This String Slime Goo Science Kit is all about the chemistry of ooey, gooey polymers that look like long, stringy, stretchy worms. You’ll learn how to hook together long chains of molecules to make cool worm-like polymers! Use both your art brain and your science brain to make amazing, rainbow-colored string slime worms! Grow stars, create worm eggs and more with this fun gooey slime scientific kit!

More about String Slime

No glue, no Borax, no messy mixing — just amazing amounts of gooey slime fun for all ages. Just mix up the Activator solution and squirt your favorite String Slime™ color into the liquid. The instant the two liquids touch, you get solid String Slime to play around with. Rest assured, the bold, vibrant color is both safe and clean.

More about Shape Gel

Combine the two liquids to create unique polymers. All you have to do is mix colors and design your shape. Then submerge into the Activator, and Voilá! You created your first polymer shape out of slime goo! Mix and match up to 16 different colors! This is a non-borax and non-glue goo slime formula that is safe and easy to use! The best part is that the amazing fluorescent colors in this slime science kit won’t stain your hands.

Slime Goo Fun for All Ages!

With our science kit, we’ve found a way to make slime goo into an exciting event for the whole family! Using a STEM approach, our goo slime incorporates lessons about polymers into a child-favorite toy that even teachers, parents and grandparents can find educational!

Making Shape Gel is a chemical reaction

It makes a new solid substance (the “star”) by combining the two liquids. The scientific name for the gooey Shape Gel liquid is sodium alginate, and it’s full of very l-o-n-g molecules called polymers.

Our Gooey Slime — Where Fun Meets STEM Science Education

It’s no secret that kids love to play with gooey slime. Slime has been a childhood staple for years, and at Steve Spangler Science, we found a way to pair our slime goo with STEM science education. In doing this, we’ve created a STEM science kit that uses slime goo to teach children about the wonders of polymers. In the five experiments included in this kit, children will engage with a variety of STEM activities that can introduce them to a whole world of science. With your supervision, you and your child can explore our gooey slime experiments together and create great memories in the process!
