Includes:
Explore the Science of Building Polymers by Cross-linking Long Chains of Molecules
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 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 powder 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.
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.
Use Under a Black Light!
Our special fluorescent colors will blow your mind under blacklight. Collect your favorite colors for the ultimate slime experience.
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.

That is correct. Each one will make approximately 32 batches of slime. The tough part is deciding with color(s)!

All the colors will be luminescent under a black light, but they do not glow in the dark.

Swee, thanks for the question. We do have a combo kit that includes 6 colors of string slime (8 oz/240 ml) per bottle. Here is the link for you to review: https://www.stevespanglerscience.com/store/rainbow-string-slime.html
Please let us know if you have any additional questions. Joshua

I am considering making this at my five year old birthday party.
Can you tell me the ingredients as some of the children will be younger.
Thank you!

i want to do this with 21 kids… i have the small squirt bottles, will one bottle be enough to divide between 21 kids? just to give them enough to make a small strand of the slime

Lisa – Customer Service Manager –
Each 32 oz bottle of String Slime makes 160 feet of string slime. If you divide this evenly between the 21 squirt bottles, this should be more than enough for the kids to make their own slime creations. Maybe buy one extra bottle just to be safe.

How long does it last…meaning when you make it, can you keep for a while?
(0) (0) Watch Unwatch
Lisa – Customer Service Manager –
As long as you store the finished slime batch in a zipper-lock bag and squeeze the extra air out. This will help it last a little longer before they dry and become hard strings of slime.

I see that one order makes 32, but how much is a batch?
Say I want to make one string; (maybe a few inches long), for 1000 people. How many strings in a batch?

Lisa – Customer Service Manager –
Every 32 oz bottle of String Slime will make approximately 160 feet of string slime or “worms”. This means, if you do it just right, you should be able to get approximately 1,920 inches out of each container.

Karen –
How much would I need to make this with 100 kids?
(1) (0) Watch Unwatch
lisabrooks –
I would recommend 3-4 bottles for 100 kids. I would recommend ordering extra Squirt Bottles to make it easier with a large group of kids. We sell a 5 pack of these bottles for $7.99.

Is there an option to buy just a bottle of the String Slime Liquid? I only need that refilled.

Unfortunately, at this time, we do not offer this option. We will bring it up with our Product Development team to see if this is something we can offer in the future.

Mandi Davis (verified owner) –
I have 3 different classes on different days, will the solution stay good if kept in a glad lock container from day to day or do the chemicals lose effect not long after the solution is mixed?
(0) (1) Watch Unwatch
lisabrooks –
If you are referencing the unused product, the product will last in the bottles provided, as long as it is stored properly. The product needs to be kept at room temperature. The product should not be frozen or stored where it can get hot. You also need to be careful of germs or bacteria getting into the solutions. This can effect the product. If you follow this, the product will last several months, maybe even a year or more.
If you are referencing the finished product (aka the “worms”), keeping them in a zipper-lock back will help them last longer over a couple of days.

Patty –
Can the green slime party pump be used to make this with the purchase of the activator solution? I have gallons of the green slime left from our science night. I’d like to do something different with it , other than just make more slime.

The String Slime is a completely different chemical reaction. The activator solution for String Slime will not work for Slime Art.

This looks a lot like the “worms” and vampire veins; is it the same experiment in different colors?
Thanks much,

It is very similar. The solutions changed a little bit as well as being offered in new, bright colors.

Our development team is planning on making a small multipack of the Slime Art, but it is currently still in the works and probably will not be available for several more months.

Is this per bottle because I want more than one color do I have to spend $100 to get what is shown on the show?

Heather – thanks for the question. We sell our string slime in liter size for $19.99 per color. If you want to get all the colors we have a product called Rainbow String Slime which includes each of the 6 colors in 8 oz bottles. Here is the link for the string slime: https://www.stevespanglerscience.com/?s=string&post_type=product
Please let us know if you have any questions and have a great upcoming weekend. Joshua
