Inside: How to make slime that’s kid-safe — No glue, no borax, and no toxic chemicals! Everything you need to know to make edible slime.
Over the past year and a half I’ve gotten a reputation as a “slime blogger” — and I’m totally ok with that!
Slime may have started as a trend, but it looks like it’s here to stay! And why not – slime is easy to make and provides hours of fun, sensory play.
We love it in our house and I love to show others how to make slime, especially slime recipes that are kid-safe, taste-safe, and worry-free!
How to Make Slime without Borax or Glue
Many of the traditional slime recipes that you’ll find on the internet are glue-based and use borax or contact lens solution as an activator. The result is super-stretchy, long-lasting slime – awesome stuff!
BUT – if you have young kids, you might worry about exposure to the chemicals used in these glue & borax slimes.
When we first started making slime, my youngest daughter was two years old and still in the stage where she wanted to put everything in her mouth. And of course she didn’t want to miss out on any activities that her older sister did, like making slime! So those glue slimes were out of the question.
Instead, we started making slime with simple kitchen ingredients. That way I didn’t have to worry about the girls touching or tasting any harsh substances.

Our Most Popular Slime Recipe EVER
Our first edible slime recipe turned out so fantastic, that I shared on my blog last year. That first recipe, Edible Silly Putty, was our most-visited post of all in 2017!
This kid-safe slime recipe changes colors when you mix it, and you only need 3 simple ingredients!
Here’s a quick demo video showing how to make silly putty slime:

Essential Safe Slime Ingredients
For our edible slime recipes, we almost always use corn starch as our base. Here’s why:
When mixed with a liquid, like water, cornstarch becomes what is known as a “non-Newtonian fluid.” In super-simple terms, a non-Newtonian fluid exhibits properties of both a liquid and a solid.
In fact, the substance formed by mixing cornstarch and water is known as Oobleck, one of the most classic slime recipes of all time. (It’s actually the first type of slime that I made as a kid!)
We love to make slime using cornstarch because of it’s morphing physical properties, and also because it is safe to touch and taste. (Even if it doesn’t taste so great by itself!)
Here’s how to make slime known as “oobleck”
How to Make Oobleck Slime
- 2 cups cornstarch
- 1 cup water
Combine 1 cup cornstarch and 1 cup water in a non-slip mixing bowl. Stir together until cornstarch is completely absorbed.
Continue adding the remaining cup of cornstarch a little at a time until your mixture thickens. You’re looking for your oobleck to feel hard when you tap on the surface, but your finger will sink into it if you press and hold.
You may or may not use all two cups of cornstarch. If you mixture starts to dry out, simply add more water. If your mixture is too runny, add a bit more cornstarch.
Tip: We love to make our oobleck in a large bowl and add mini-figures to the mix. The girls love to watch their figures sink into the slime!
Now let’s talk about how to make slime by taking the basic Oobleck recipe to the next level!

Slime Troubleshooting – How to Make Slime Perfectly Every Time
Making slime isn’t an exact science, and sometimes you simply need to play around with it a bit to get the perfect consistency.
If you don’t get it right at first, don’t throw that slime away! It’s actually pretty hard to completely “mess up” our edible slime recipes, and they can usually be easily fixed!
If your slime is too dry or starts to crumble:
Add more of your liquid ingredient, one teaspoon at a time. (This is also how you can re-hydrate slime that has been sitting out for a few hours).
If your slime is too sticky:
Add cornstarch, one tablespoon at a time, kneading into your slime or dough until it no longer sticks to your hands.
The most important thing:
With most of our slime recipes, it can take a few minutes of stirring and mixing to achieve the perfect slime consistency. Don’t worry if your slime isn’t ready in seconds — keep following the instructions for how to make slime in each of our recipe posts and you’ll get it!
Storing Your Slime
Since these safe slime recipes are made with food ingredients, they won’t keep for weeks like glue-based slimes. The good news is that these edible slime recipes are usually inexpensive to make, and they are safer than glue and borax slime!
These edible slimes are best enjoyed the day they are made, but you can store in an air-tight container in the fridge for a day or two. You may need to rehydrate before playing the next time. I also don’t recommend tasting these slimes after the first day of play.

How to Make Slime Safely
Making slime is TONS of fun, and the recipes we share here are designed to be safe for kids to play with under adult supervision. However, it is still important to review safety guidelines. We love to share recipes, but we also want to make sure we talk about how to make slime safely.
Following the tips below will help ensure that your slime experience is all fun!
- While our taste-safe slime recipes are technically edible, they’re not meant to be consumed as food. Always supervise kids when playing with slime, even taste-safe slime.
- All slime recipes have the potential for safety issues. All activities and slime recipes on this website should be used or tried with your good judgement and common sense.
- Every child is different in their capabilities, so be sure to consider the age-appropriateness of each activity for individual children. Never leave children alone when playing with any type of slime.
- It is advisable to make slime on non-porous surfaces that can be easily wiped down and cleaned afterwards.
- Always wash hands thoroughly after any trying any slime recipe. Some ingredients may stain hands temporarily (like brightly-colored Jello), so we stick to cool colors that are less likely to stain, like green.
- We also recommend wearing play clothes or an apron when making slime to prevent staining of clothing.
- The Soccer Mom Blog is not responsible for any damages incurred by trying any of the slime recipes listed on this website.
