Learn how to make satisfying slime and many different types of slime below!
What is Slime?
Slime is something that fascinates both kids and adults alike. But when you get down to it, what is slime, really?
We like to explain it in the science of slime.
Slime is a non-Newtonian fluid, meaning that is has both properties of a solid and a liquid. It can be compressed like a solid, but it also flows like a liquid.
Slime is made up of polymer chains just like flexible plastic. When the boric acid mixes with the PVA glue, the molecules combine into flexible polymer chains.
Over time, because slime is made from glue, it will harden, and you can make some pretty cool things out of hardened slime, too!
The Benefits of Slime
There are 101 reasons to make slime, but one big reason not to.
The big reason NOT to make slime is that it can be messy.
However, I think the benefits far outweigh the mess! And, there are plenty of non-messy slime ideas that you can do if you’re really not wanting things to be a mess when making slime.
But here are some reasons you SHOULD make slime:
- It’s a wonderful sensory activity
- It promotes STEM awareness
- It’s a fun chemistry science activity
- Kids LOVE it
- It makes a fun gift
- There are so many fun slime variations to try
- It can build hand strength and pre-writing skills
- It can be therapeutic for kids with sensory needs
Whatever your reason for making slime, we have all the recipes for slime you’ll need to make your slime making experience epic! Now that gives you some ideas of what to do with slime!
Why is Slime Satisfying?
Slime is satisfying for a variety of reasons- but the main reason it is satisfying for so many is that it is a sensory experience.
There is something that feels good about sticky, stretchy slime when you touch it and play with it.
Slime is used a lot in play therapy for children with sensory needs, like those who are autistic, have ADHD, or have other neurodevelopmental differences.
Slime is not only fun and soothing, but it also encourages proper childhood development. including a boost to language skills, problem-solving skills, and cognitive abilities.
So, allowing a child to play with slime, while it may cause a bit of stress in the moment, is actually doing wonders for a child’s development and mental health.
So, let the slime play continue!
Different Slime Recipes for Kids
We all know that buying slime all the time can get expensive.
So why not make your own slime at home?
There are a million ways to make slime, and part of the fun is how much variation there is to try!
All slime will need a base (PVA glue is usually used) and a chemical reactor that will thicken the slime.
We’ve made slime from soap, glue, sugar, xanthan gum, and cornstarch, but you can make it from almost anything!
Experiment with different materials and ratios to make a slime that is unique to you! Slime forms when the two materials mix and create a chemical bond known as a polymer chain. This is a stretchy substance that is fun to play with!
Our favorite slime uses a mixture of laundry starch and PVA glue. You can find the recipe for that in our post about how to make slime with liquid starch.

Common Slime Problems
There are two problems that often occur when making any slime recipe. Here’s how you can fix either one!
Why is My Slime Watery?
Watery slime usually means you messed up the ratio, but it’s usually completely fixable. If your slime is too watery, try this:
- Add more activator. It could be you just didn’t add enough activator!
- Pour off excess liquid. It could be that you added too much water or activator and need to pour off some access.
If that doesn’t work, try adding a bit more glue.
Why is My Slime Sticky?
Sticky slime usually means you don’t have enough activator. Try adding a bit more.
If that doens’t work, you may need to add something dry, like cornstarch, to help reduce how sticky your slime is. I like to add either cornstarch or shaving cream to eliminate stickiness.
Still have trouble with your slime? Check out the slime troubleshooting guide and learn how to fix it so you don’t have to throw out any expensive slime-making supplies.
What is the Most Popular Slime Recipe?
All of our recipes for making slime work, but by far, the most popular slime recipe is this one!
When making slime, we like to use a ratio of 2/3 part water, 1 part laundry starch, and 1 part glue. Our slime comes out perfect every single time!
We also like to use soap dyes because they create vibrant colors that really pop without staining hands, counters, or furniture.
What Are the Ingredients to Make Slime?
It doesn’t take a lot of expensive supplies to make slime. In fact, there are only three main ingredients to make slime!
However, before you get started making slime at home, you’ll want to make sure you have the supplies listed here.
- Laundry starch
- Elmer’s glue
- Soap coloring
- Storage jars
- Borax powder
- Shaving cream
- Contact lens solution with boric acid (your slime will not work without boric acid)
- Measuring cups and spoons
- Mixing bowls
- Metal fork (my favorite way to mix up slime!)
