Rainbow Slime Kit for Kids

Make Colorful Wiggly Worms While You Explore Polymer Science!

Amazing fluorescent colors won’t stain your hands

This is slime like you’ve never seen before. No glue… no Borax… no messy mixing… just amazing! 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.

Remove the strings from the bowl and you’re ready to play. Snap the string in half to reveal the gooey center. Just dip the ends into the Activator Solution to seal it back up.

What does it teach?

Explore the science of building polymers by cross-linking long chains of molecules. The process of making Rainbow String Slime is faster and easier than the classic slime recipe and it happens the very second the two liquids mix. Truly amazing!

What age is this activity best suited?

This activity is great for all ages. Both String Slime liquid and the Activator Solution is safe to use as directed with adult supervision. Use String Slime as an introduction to chemical changes for young children, while older children will learn about polymer science through the process of cross-linking long chains of molecules together.

Even Grownups Play With Polymers

Polymers, which are long carbon chains of repeating subunits, have hundreds of practical applications in the real world. Chemists who work in research labs love to play with them to get them to do all kinds of useful things for humanity. We see polymers in electronics, in coatings and adhesives, in the automotive industry, and even in medical devices. That’s why it’s a wonderful idea to let children learn about polymers early in their education, and with Rainbow String Slime from Steve Spangler Science, learning about polymers can be fun. Once the youngsters get past their initial excitement over the appearance of neon-colored strings that form in the activator solution as soon as they squirt in the slime, they can do the activities in the Activity Guide that’s included in order to learn more about how this wonderful rainbow string art actually works. Then, who knows? Maybe they’ll want to keep going even when they attend college and beyond.

Rainbow String Slime

You Won’t Believe Your Eyes!

Best of all, String Slime won’t stain your hands. It’s safe to touch, twist, twirl, and explore the science of polymers.

    What do you do with the slime when the kids finish playing? Can we save it for a next time?

      Absolutely you can! We recommend storing the slime in a plastic zip-lock bag until you’re ready to play with it again!

    Monica Alexander

    Hi Mr. Spangler, I teach in a high minority, poverty school district. I have a 160+ students. I do so want to wow them. Get them excited about science. What is the best and I hate to say the cheapest way to go. I will be paying for this myself. Can you please help.
    Thank you have a great day

  4. Question

    Hillary

    I see that you no longer sell the activator by itself…I am looking for 6 kids to have their own bowls to create their own string slime at the same time. Will I be able to accomplish this with the amount of activator in the kit, or is the intent for 1 bowl and only enough activator for the 1 bowl?

      Hi Hillary! You will want to mix the solution and then separate it into the individual bowls.

      We estimate that one kit is enough for about 16 kids working together so for 100 students we recommend 7 kits.

      This is a tough one to answer, but we would suggest this kit is good for up to 16 kids working together.

    Will this set be enough for 5 children to experience each color? Does it have to be in a clear glass bowl? Is there enough solution for 5?

      Yes, this most definitely has enough solution and activator for 5 children.

    Question

    Ashley

    I am wanting each child(10-20 kids) to have their own bowl to use for the string slime. Do I need to buy more activator solution for each bowl or just put a little in each bowl?

      Yes, I would recommend ordering an extra bag of activator just to make sure you have plenty for the kids to do the experiment.

  10. Question

    Kathleen Schaefer

    I would like to use this as a center along with a book during our summer reading program. We would rotate small groups in throughout a 6 hour period of time. There would probably be about 8 groups with 12 kids each. I can limit how much product the kids will use each group. I guess my question is, how much product would each group need to use for a satisfying activity? Do they use a whole bottle each time?

      Kathleen – thanks for the question. I would probably suggest purchasing our 1 liter size of the string slime, a purchase of 6 liters should be enough for the full session. Please call me if you have any other questions.

    longdeademperor (verified owner)

    I love the Rainbow String Slime. It is amazing and really exciting for the children. If it accidentally gets on a towel or other cloth fabric and dries out, is there a way to get the slime off easily? Do you use salt or soap or vinegar?

  12. Question

    Henry Goodwin

    In August I saw Steve’s “DIY Science” TV show in slime. Near the end of the show he made balsa by putting clear slime in a measuring spoon, along with some colored. When he dipped it into the activator solution, it formed a small ball. Did he use th is strong slime or the “standard slime” materiaks?
    Thank you in advance for helping me with this.
