How to Make Crunchy Slime



Slime has become a popular trend among kids and adults alike. Its gooey texture and endless possibilities for customization make it a fun and engaging activity. While there are various types of slime, one that has gained significant attention is crunchy slime. In this article, we will explore the step-by-step process of making crunchy slime, discuss the materials needed, and provide valuable insights to ensure a successful slime-making experience.

Materials Needed

Before diving into the process of making crunchy slime, it is essential to gather all the necessary materials. Here is a list of items you will need:

  • White school glue
  • Water
  • Borax powder
  • Polystyrene foam beads
  • Food coloring (optional)
  • Measuring cups and spoons
  • Bowls for mixing
  • Stirring utensils

Step-by-Step Process

Now that you have all the materials ready, let’s dive into the step-by-step process of making crunchy slime:

Step 1: Prepare the Borax Solution

The first step is to prepare the borax solution, which will act as the activator for the slime. Follow these instructions:

  1. Dissolve 1 teaspoon of borax powder in 1 cup of warm water.
  2. Stir the mixture until the borax powder is completely dissolved.

Step 2: Mix Glue and Water

In a separate bowl, mix 1 cup of white school glue with 1/2 cup of water. Stir the mixture until it is well combined.

Step 3: Add Food Coloring (Optional)

If you want to add color to your crunchy slime, this is the time to do it. Add a few drops of food coloring to the glue and water mixture and stir until the color is evenly distributed.

Step 4: Combine the Borax Solution and Glue Mixture

Slowly pour the borax solution into the bowl containing the glue mixture. Stir continuously as you pour.

Step 5: Knead the Slime

Once the mixture starts to come together, use your hands to knead the slime. The more you knead, the firmer and less sticky it will become. If the slime is still too sticky, add a small amount of borax solution and continue kneading until you achieve the desired consistency.

Step 6: Add Polystyrene Foam Beads

Now comes the fun part! Add a handful of polystyrene foam beads to the slime and knead them in. The beads will create the satisfying crunch that gives this slime its name. Feel free to add more beads if you prefer a crunchier texture.

Step 7: Enjoy Your Crunchy Slime

Your crunchy slime is now ready to be enjoyed! Stretch it, squish it, and listen to the satisfying crunch as you play with it. Store it in an airtight container when not in use to keep it fresh and prevent it from drying out.

Benefits of Crunchy Slime

Crunchy slime offers more than just a fun sensory experience. Here are some benefits of playing with crunchy slime:

  • Stress Relief: The act of kneading and manipulating the slime can help relieve stress and anxiety.
  • Fine Motor Skills Development: Playing with slime can improve hand-eye coordination and fine motor skills.
  • Sensory Stimulation: The unique texture and sound of crunchy slime provide sensory stimulation, which can be beneficial for individuals with sensory processing disorders.


Q1: Can I use a different type of glue?

A1: While white school glue is commonly used for making slime, you can experiment with other types of glue, such as clear glue or glitter glue, to achieve different effects.

Q2: Can I substitute borax with another activator?

A2: Yes, if you prefer not to use borax, you can substitute it with other slime activators like liquid starch or contact lens solution. However, the measurements and process may vary, so be sure to follow the instructions specific to the activator you choose.

Q3: How can I make my crunchy slime less sticky?

A3: If your slime is too sticky, add a small amount of borax solution or activator of your choice and continue kneading until the stickiness is reduced. Avoid adding too much activator at once, as it can make the slime too stiff.

Q4: Can I add other mix-ins to my crunchy slime?

A4: Absolutely! You can get creative and add various mix-ins to your crunchy slime, such as glitter, sequins, or even small toys. Just make sure the mix-ins are safe and won’t cause any harm when playing with the slime.

Q5: How long does crunchy slime last?

A5: With proper storage in an airtight container, crunchy slime can last for several weeks. However, over time, the foam beads may lose their crunchiness. If that happens, you can add more beads to revive the texture.


Crunchy slime is a fun and engaging activity that provides not only entertainment but also various benefits. By following the step-by-step process outlined in this article, you can create your own crunchy slime and enjoy the satisfying crunch it offers. Remember to gather all the necessary materials, experiment with different colors and mix-ins, and store your slime properly to prolong its lifespan. So go ahead, get creative, and have a blast making and playing with crunchy slime!
