Once you know how to make slime, it's time to make the crunchy kind!

Once you know how to make slime, it's time to make the crunchy kind!

Calling all future scientists — we’ve got another ooey-gooey STEM experiment for you to do! This time, our slime goes crunchy. Get ready to make twisty, gooey, swirly slime with an added layer of crunchiness.

Our slime acts as a non-Newtonian fluid, which means it’s technically both a liquid and a solid at the same time! With our glue acting as a large chain of molecules, called a polymer, reacting to borax, we get our gooey concoction. But what would happen if we made it crunchy using a rather tactile petroleum-based ingredient, like Styrofoam beads? Thanks to petroleum-based products, we’re able to make STEM experiments possible for every at-home scientist!

Crunchy Slime

What You’ll Need:

  • ½ cup ok white school glue
  • 1 squirt of foaming shaving cream
  • 2 pumps of foaming hand soap
  • 3 pumps of lotion
  • Glitter
  • Borax
  • Food coloring
  • Foam beads


  • Pour a ½ cup of white school glue into a bowl.
  • Add 1 squirt of shaving cream, 2 pumps of foaming soap and 3 pumps of lotion to the bowl.
  • Mix together.
  • Add in glitter and your favorite food coloring to the slime mixture (feel free to use Valero blue and yellow — our favorite colors!).
  • In a separate container, mix the borax with water, but make sure you’re using the same amount of both to create the perfect borax solution.
  • Slowly pour the borax solution into the slime, working it through with your fingers to find the right consistency.
  • To make your slime crunchy, add in some foam or plastic beads. Make sure you mix them in well to make your slime extra-crunchy!


  • If slime becomes too sticky after playing, add in more borax solution.
  • If things get a little messy, vinegar will take the slime out of clothes, and mayo will take it out of hair.
  • Make sure to clean up your lab when you are done! To remove slime easily, just pour a little bit of borax on the tabletop to make it pliable.
