What substance is fun to make, irresistibly squeezable and infinitely customizable? It's homemade slime! You can make your own batches of slime with just three main ingredients: water, white glue and borax powder. With your own creative add-ins, you can make as many variations on this basic recipe as you'd like.

What Is Slime? Why Would You Want to Make Some?

Homemade slime is a touchable, squeezable, pliable, can't-keep-your-hands-off-of-it sort of substance. Is it a solid? Is it a liquid? You'll have to make your own batch and decide for yourself.

Slime is best compared to a putty. You can stretch it, squish it, and try your best to mold it. Set it down, and it will slowly flow across a surface. In other words: Slime is fascinating.

It's also a tactile wonder. Both kids and adults will enjoy the feel of slime between their fingers. Add color or glitter so your slime will be just as fun to look at as it is to play with.

If slime's impressive physical properties aren't enough to motivate you and your children to make a batch, consider that this activity is also an educational science experiment. Young children can learn that mixing various substances together can result in an entirely new substance. Older children--and their parents--can use this putty-like substance to explore the fascinating properties of non-Netwonian fluids.

How to Make Slime

Preparing a batch of slime is an activity that children and adults can do together. It's a simple project that gives children experience with cooking skills like measuring and stirring.

Ingredients

  • 1 8-ounce bottle of white glue. Elmer's Glue is the most-often recommended glue for this project
  • 2 cups of water, separated
  • 1 tablespoon of borax powder

Supplies

  • Mixing bowl
  • Measuring spoons and liquid measuring cups
  • Clean hands that are willing to get a little messy in the name of having fun!

Instructions

  1. Spoon 1 tablespoon of borax into 1 cup of water. Stir to dissolve. Set this mixture aside.
  2. Empty the contents of the glue bottle into the mixing bowl. Add an equal amount of water to the bowl.
  3. Use your hands to gently combine the water and the glue until they are thoroughly mixed.
  4. Gradually add the borax mixture to the glue mixture. Continue to mix the glue with your hands as you add the borax.
  5. Once all of the borax has been added, use two hands to knead the solution. Eventually, the mixture will have a smooth, uniform texture.
  6. When you're happy with the feel of the mixture, your slime is ready to use. It's time to play!

Add-ins and Variations: How to Customize Homemade Slime

There are countless ways to change up the basic slime recipe. Once you discover how easy it is to make homemade slime, you'll find yourself making new variations on a regular basis.

Colored Slime

All it takes is a few drops of food coloring to dye your batch of slime any color of the rainbow. The trick is knowing when to add it.

After thoroughly mixing the glue and water, add a few drops of food coloring. Two to four drops should be sufficient. Use your hands to stir the glue until the color is evenly spread throughout the mixture. Once the color is uniformly distributed, you can move on to the step of adding the borax.

If you add food coloring to your slime, use caution around carpet and clothing. The color in the slime can stain textiles.

Clear Slime

To prepare clear slime, substitute Elmer's Clear Washable Glue for the white glue. Other than that switch, you will follow the normal slime directions.

Clear slime usually turns out thicker than regular slime. If you want your finished product to be less thick, slightly reduce the amount of glue you use, but keep the amount of water the same.

Glitter Slime

Give your batch of slime a festive sparkle by shaking a splash of glitter into the mixture. Just like food coloring, glitter should be added after mixing the glue and water together. It needs to be added before putting the borax in.

Of course, you can add both color and glitter to the slime. Or, instead of glitter, you can use confetti, sequins, or other small objects.

Magnetic Slime

Adding iron filings to your slime will produce a final product that can be moved and manipulated with a magnet. Add the iron filings to the water and glue mixture before you add the borax.

Frequently Asked Questions

What if your slime feels lumpy or stringy?

This is a normal stage of the slime-making process. Don't worry; you haven't done anything wrong. Your slime just isn't quite ready for play yet. Keep kneading the mixture, and you'll soon have a nice, smooth ball of slime.

What if you don't want to stir the slime with your hands?

Although slime washes easily off of hands, there's a touch-free method that you might want to try for making slime. Instead of a mixing bowl, use a container with a tight-fitting lid. Follow the above directions for making slime, but instead of mixing the ingredients with your hands, close the lid and shake the container. After adding the borax, about 10 minutes of shaking should be enough to develop the slime.

Can you eat the slime?

No, borax is not something that you should consume. Please supervise children while playing with slime, and make sure that they are old enough to understand that slime should not be put in mouths. Wash hands after playing with slime.

What is the best way to store slime?

Slime can last for some time if kept in an airtight container. Consider storing your slime creation in a zip-top bag or a reusable plastic food container. It can be kept at room temperature, but it may keep longer in the refrigerator.

It's Time for Slime!

Are you ready to mix up your own batch of this playable, stretchable, squishable slime? All it takes is a few simple ingredients and a parent-child pair that is ready for fun. Stick with the basic recipe, or include your own creative add-ins. However you choose to make it, your batch of homemade slime will entertain both kids and adults.
