This post may have affiliate links. Please see my disclosure.

Slime has been a popular craft among children for generations. We are often asked which is the best glue for making slime.

The short answer to that is a washable school glue.

How did slime become popular?

It first began as a fun little hobby for Halloween.

Today it’s often seen as an activity for all kinds of reasons. Especially for summer camps, schools and science clubs.

Slime is supposed to be non-toxic, and it includes household ingredients like glue. This makes it especially popular with teachers or parents on a fixed budget.

Kids also love making slime because it’s a fun learning tool.

They love showing how poking it will make it go solid. Also how it quickly reverts back to its gooey liquid form.

Plus, as kids often do, they always enjoy getting to be messy and creative.

What Goes Into Slime:

There are numerous recipes for making slime, but the most common recipe involves the use of liquid school glue water and corn starch.

Many kids also love being able to use food coloring to dye their slime any way they want. Green, purple, orange, even turquoise!

Many color combos can be created by mixing the three basic primaries of red, blue and yellow.

Best of all, although it shouldn’t be eaten, school glue is non-toxic, making this craft a very safe choice, as well.

Why specifically bottled school glue for making slime? The liquid school glue is runny, moves well. It’s washable and easy to clean up, and it works best with the other ingredients.

Similar liquid glues such as that from glue guns or model airplane kits don’t work properly.

Stronger hardware glues, like Krazy Glue for example, dry too fast and can stick to skin. This can cause a painful situation if it’s not handled by an adult.

School glue has been preferred for years now in the slime-making process, and it’s easy to find in most stores.

These ingredients are also great for children with allergies or skin sensitivity because there’s no harsh chemicals or irritants involved.

How Ingredients Should Be Mixed:

The great thing about making slime is that how you want to do it is mostly up to how much you want to make.

Start with a large glass or plastic mixing bowl, squeezing in as much glue as desired. For parents doing this craft in the home, it’s recommended that you don’t use the whole bottle, because you may end up with more slime than you want.

For classrooms or camps with multiple children participating, you’ll probably want to have a lot more glue on hand, and you may wish to buy a larger jug of school glue instead of the usual squeeze bottle.

Quickly, before the glue has a chance to start drying, pour corn starch and water into the bowl while having somebody there to knead the mixture with their hands until they get the consistency they want.

You don’t want the slime to be too runny, otherwise it will just separate out and not last very long. A good thickness to try for is to get it about as runny as heavy syrup.

How Slime Should Be Stored:

That’s entirely up to you. Many people use a small but sturdy container, such as those old plastic Kodak film canisters, which is also a good way to recycle them without just throwing them in the garbage.

You can also use a plastic sandwich bag, preferably one with a good seal. Or a food storage container like a small plastic Tupperware tub.

Slime can last a while depending on a number of factors. It probably shouldn’t be held onto for longer than three months because of the possibility of it attracting mold or moisture.

Keep it away from flames, intense sunlight and pets. If you live in an area prone to humid or hot weather, it’s a good idea to keep the slime in the refrigerator until your child wants to play with it.

Fun Add-Ins For Slime:

Glitter flakes can give slime a whole new look, especially if you’re having it made as a holiday craft, like Christmas or Halloween.

One of the most fun types of glitter is Sparkle Metallic Confetti, which usually comes in large plastic cans.

Different kids like different things, so it’s a great chance for them to let their imagination loose and mix things up! Small rubber zoo animals and farm animals, usually available in dollar stores, can also be a fun option for kids to put in.

Keep in mind though that too many extra add-ins can weigh down the slime and make it fall apart. It may be best to keep it down to only one plastic animal per container of slime, and a few shakes of glitter to avoid putting in too much.
