Slime is a great way to get kids interested in science and engineering.

It is also a fun pastime for children, as they love to play with slime and it is generally fun to create.

Slime is also known as goo or mucus, and it’s very simple to make. All you need is cornstarch, water, food coloring, and some other ingredients.

You can easily make slime without glue by combining cornstarch and water. The mixture should be thick enough to form into balls, but not too sticky. Then add food coloring and mix well. Let the slime sit overnight before playing with it.

So, without further ado, let’s look at how to make slime without glue!

How To Make Slime Without Using Glue

You can use this recipe for making slime at home.


  • 1 cup of cornstarch
  • 2 cups of cold water
  • Food Coloring (optional)

Directions In Steps

  1. Mix 1 cup of cornstarch with 2 cups of warm water until smooth.
  2. Add food coloring if desired.
  3. Let the slime sit overnight before play time.

This slime recipe works best when made with cold water. It’s important to keep the water cool because hot water makes your slime runny. If you’re having trouble getting your slime to stay put, try adding more corn starch.

How Long Will The No Glue Slime Last?

The slime will last about a week if stored properly. You can store the slime in an airtight container away from sunlight.

If you want to make slime that lasts longer than one week, you can add gelatin to your slime. Gelatin is used in many foods, such as Jell-O.

Gelatin is added to the slime mixture to help thicken the slime and extend its shelf life. To do this, simply dissolve two teaspoons of gelatin in a small amount of water. Stir the solution thoroughly and then add it to the slime mixture.

Gelatin is available at most grocery stores. You may also find it online.

What Kind Of Food Coloring Works Best For Making Slime?

There are hundreds of different colors that work well for making slime. Some people prefer using natural colors while others like to use bright colors.

Natural colors include red, yellow, orange, green, purple, blue, brown, black, white, pink, and gray. Bright colors include red, yellow/orange, green, blue, violet, magenta, and aqua.

To choose the right color for your slime, experiment with different combinations. Try mixing several colors together.

For example, you could combine red and yellow to make orange. Or you could mix red, yellow, and blue to make purple.

Once you’ve found a combination that looks good, you can start experimenting with different amounts of each color.

Try starting out with just half a teaspoon of each color. Gradually increase the amount of each color until you reach the desired shade.

When choosing which colors to use, remember that brighter colors tend to fade faster. So, if you want your slime to last longer, choose darker colors instead.

You can even use any food coloring that you’d normally use to dye eggs! Just be sure not to use food coloring that contains alcohol.
Alcohol can damage the plastic tubing that holds the slime together.

How Much Cornstarch Should I Use?

How to Make Slime Without Glue

Adding too much cornstarch will cause your slime to become too stiff. Too little cornstarch means your slime won’t hold up well.

It’s recommended that you use between 1/4 cup and 1/2 cup of cornstarch per batch of slime.

How Do I Know When My Slime Is Ready?

Your slime should have a consistency similar to Play Doh or modeling clay. If your slime seems too sticky, add more cornstarch.

If your slime feels dry or hard, add more water.

Can I Use Other Ingredients Instead Of Cornstarch?

You can use other ingredients to replace some of the cornstarch.

These include: baking soda, arrowroot powder, powdered sugar, flour, ground oats, powdered milk, powdered egg whites, powdered peanut butter, powdered cheese, powdered chocolate syrup, powdered cocoa, powdered vanilla extract, powdered cinnamon, powdered nutmeg, powdered salt, etc.

How Can I Store My Slime?

Store your slime in an airtight container. Plastic containers work best because they keep moisture away from the slime.

Store the container in a cool place (not above 40 degrees F). The warmer the temperature, the shorter the shelf life of your slime.

How Long Does It Take To Dry Out?

The time it takes to dry out varies depending on how thick your slime was when you started.

Thicker slime takes longer to dry than thinner ones.

A thicker slime tends to absorb more water during its drying process. This causes the slime to get drier slower.

A thin slime doesn’t need as much water to remain moist. As a result, it dries a lot quicker than a thicker piece of slime.

What Are Some Tips For Making Slime?

Here are some tips to help you make slime:

  • Use a spoon or spatula to stir the mixture while adding water. Stirring helps prevent clumps from forming.
  • Stir the mixture every few minutes so that it stays smooth and creamy.
  • Add small amounts of water at first. Then gradually add larger amounts as needed.
  • As you add water, watch out for bubbles. Bubbles can ruin your slime by making it look cloudy.
  • Don’t let your slime sit around for long periods of time. It needs to be used within 24 hours after mixing.
  • Keep your slime stored in an airtight container to prolong its shelf life.

Final Thoughts

Making slime is fun and easy. It is also a great thing to do with your children as it provides entertainment, as well as teaches them about science.

You also do not need a lot of tools or ingredients. This makes it a simple activity that will provide enjoyment, no matter the age.

So long as you have water, cornstarch and food coloring, you will be able to make plenty of slime in a variety of different colors!
