How to Make Slime Easy for Kids to have Fun

Children love dirty, messy projects, and while we as adults often buck against these desires, as parents, we’re obligated to give in from time to time, such as teach them how to make slime.

Trust us. Saying ‘no’ to everything turns into a disaster that’s out of your control.

Instead, take on a project with your kids that’s easy and relatively easy to clean up. Making slime with your kids is also quality time spent together and messy enough to make your kids happy.

You can find most of the ingredients for slime (or whatever you want to call the gooey substance) in your home. And just in case, we’re helping you out with multiple recipes here so you can find one you don’t have to hit the store to fulfill!

Take a look at this variety of easy-to-use recipes on how to make goo that can help you make slime easy for kids.

1. Get Corny with Cornstarch Slime: How to Make Slime with Liquid Starch

how to make slime

There is no easier way to create the gooey material for your kids than to use cornstarch, an ingredient that’s likely been hiding in your cupboard anyway. Why is this such a great option?

First, it’s all natural, and there’s nothing about it that could possibly be toxic to children. That means it’s suitable for even very young kids.

Second, it requires only two ingredients – cornstarch and water. It can’t get any simpler than that!

For the right consistency:

  1. Start with 2 parts cornstarch, 1 part water.
  2. Put the cornstarch in a bowl.
  3. Add water a little at a time, mixing thoroughly, until you reach the consistency desired.

You can also add food coloring to your slime. That definitely makes it more fun for the kids!

Be sure to store the goo in an air-tight container if you want it to last. Also, use this as a learning experience, like a science experiment that shows your kids how to make something more liquid or solid.

2. Better If Edible

If you’re going to enter into a fun endeavor with young children, you need to be prepared when figuring out how to make goo. Everything gooey goes in the mouth, so making edible slime goes a long way in avoiding problems.

As a bonus, this particular edible slime glows in the dark! All you need is a blacklight to make it shine blue-white.


  • 1 teaspoon soluble fiber (such as Metamucil)
  • 1 cup tonic water
  • Food coloring (bonus: make it red, and you have fake blood for Halloween)

Simply stir the fiber into the tonic water and add a couple drops of food coloring. The mixture won’t be sticky, but it will certainly be slimy, just right for playing around!

Note that this is edible but won’t taste good. That may benefit the cause, stopping children from eating too much of it – but if you don’t mind them enjoying the flavor, add a little sugar to make it palatable.

3. How to Make Goo with Borax

If your children are a little older and not prone to putting everything in their mouths, borax is a great ingredient you’ll find in the laundry aisle to use for slime.

You can alter the recipe, if you want, to make it glow (using paint that glows in the dark in the mix) as well as adding some neon food coloring (for true slime, use neon green). The full list of ingredients below creates enough for two small half-jars.


  • 4 oz clear or white glue
  • 1 cup luke warm water
  • 1/3 cup luke warm water (separate from the other cup)
  • 2 teaspoons of borax
  • 2-3 tbsps of paint (glow in the dark stuff) or other paint for coloring
  • Food coloring (neon green is perfect)


  1. Mix together the glue and the cup of warm water, and then stir in the paint and food coloring you’ve decided to use.
  2. In another bowl, mix the borax with the 1/3 cup of warm water. Careful – you may not use all the borax and should add it slowly while stirring to get the right consistency.
  3. Stir the two mixtures together until they start sticking together and create the slime consistency your children like.

Be aware that consumption of the mixture could become a problem, especially in large quantities. Borax shouldn’t be your material of choice if you have very young children.

Also, when choosing the paint you intend to use, make sure it’s suitable for children. Some craft paints still include ingredients that aren’t safe for play.

4. How to Make Slime with Glue and Water!

One thing you can bet on is that glue you buy for your kids to use in school is a fairly safe product to use for projects at home. We’ve found that, when a recipe calls for glue, Elmer’s is typically a great choice (there are others that are equivalent).

But let’s talk about the absolute ease with which this particular form of slime is made.

You only need two ingredients: 1 ½ cups of clear glue and 1 ½ cups of liquid starch. Or, for a smaller (or larger) batch, match the ingredients part for part!

A few tips you might want to consider when figuring how to make slime with glue and water:

  • Liquid starch is available at the local grocer on the detergent aisle or online at Amazon and other sellers.
  • Check the brand you decide to use, and make sure it’s non-toxic. Even older children should be safe when using the slime.
  • Divide out the final product so you can put different food colors in it. Your kids will love the rainbow of slime!

5. Silly Slime? Or Silly Putty?

Some of the recipes for slime can be configured to make an at-home version of silly putty, which can be even more fun for kids who aren’t excited about getting the gooey material all over their hands.

Plus, silly putty has other uses, like picking up the colors from the newspaper comics. You probably did that as a child!

For the best silly putty, we found that adapting this slime recipe works well:

  1. Empty a 7.5 ounce bottle of Elmer’s (or similar) glue into a large bowl.
  2. Add a squirt of paint for color (to your liking).
  3. Start adding liquid starch and mixing slowly. A spatula gets things going, but after a few seconds, you might want to use your hands to get the right texture.
  4. Add starch as the mixture begins to stick to itself, until it thickens to a clay-like consistency.

Less starch will still be sticky, and that can make a great slime. However, if you’re looking for something that isn’t sticky at all and works like clay or silly putty, you’re going to use close to double the amount of starch.

6. Look at That – We’ve Got Gak!

created the perfect slime for several of their television shows back in the 80s. Then, they started packaging it and putting it on toy store shelves under the name of Gak.

We can’t count the number of times our kids have begged to spend some of their allowance on a package of Gak. Luckily, we’ve found a recipe that mimics the gooiest substance almost perfectly.

The ingredients are similar to other recipes, but you’ll find the proportions a little different. And we still recommend care with younger children, since the recipe calls for borax (albeit in a minimal amount).


  • 8 oz Elmer’s Glue
  • 1 teaspoon borax
  • 1 cup warm water
  • ½ cup warm water (separate)


  • Plastic cup
  • Bowl
  • Food coloring

Start by squeezing all the glue into a bowl. Then, fill up the bottle with warm water, shake, and pour into the bowl with the glue. Stir.

Add the food color of your choice. Typically, it doesn’t take much to color your glue and water mixture, but you can add more for a brighter look.

In the cup, pour your ½ cup of water and add the borax. Mix it until the borax dissolves completely.

Pour the borax water into the glue bowl, and stir until you see the substance get stringy. Then, put down the spoon, spatula, or other tool, and dig in with your hands.

Squeeze and squish with your hands until you have a gelatinous mixture on your hands (literally!). Then, you can turn it over to the kids and let them play around until it turns to goo that is the same consistency as Gak.

Easy solution, and you’ll spend less money, since all the ingredients can be used for several rounds!

It’s important to find ways to spend quality time with your children, and even if you aren’t the craftiest person, you can follow through with projects like making easy slime with your children. You can keep the recipe and put it into even more important use around Halloween, using it for fake blood or brain matter.

It’s great to explore various colors for other holidays, too! Make some green and red for Christmas, pink for Valentine’s Day, and red, white and blue for Independence Day!
