The Science of Slime

Traditional slime is made when boron mixes with the polymer chains in the glue, creating strong, but flexible bonds between the molecules.

When you add shaving cream into the mix, you get a whole new element of fluffy slime fun! The shaving cream gives the slime a puffy texture, which is so fun to squeeze and stretch.

My kids prefer fluffy ice cream slime to any other slime recipe!

Since fluffy slime does contain borax, if you have a sensitivity to it, you may want to try how to make slime with baking soda instead.

How to Make Fluffy Ice Cream Slime

Making slime recipes is one of our favorite science activities ever. Read on to see how to make the very best fluffy ice cream slime!

My kids noted that their fluffy ice cream slime looked just like astronaut ice cream slime!

Fluffy slime is not the easiest slime to make. Learning how to make slime with liquid starch and clear glue is the easiest slime recipe.

When you add in shaving cream, the chemical balance is a little different and the tendency will be for the slime to be a bit stringy at first.

There are ways to get around this, which I discuss in my slime troubleshooting guide, but in general, if you work through the stringiness and your ratios are correct (as outlined below), then you will end up with perfectly fluffy slime and you won’t have to throw it out.

If you don’t want to waste a lot of ingredients, try mixing up a small batch first to make sure you won’t have to tweak it before you make the larger version.

We always stock up on gallon sizes of glue and the large laundry starch just in case something goes wrong.

Difficulty: easy

Give Neapolitan ice cream slime a whirl1 This fluffy ice cream slime easy and enjoyable for the whole family! All you need is a handful of ingredients like Elmer's glue, food coloring, shaving cream, and laundry starch. Plus, learning how to make ice cream slime is a great way to spark creativity. So don't wait--take a scoop of this delightful ice cream fluffy slime recipe today!


  • Liquid laundry starch
  • Shaving cream
  • Brown, pink, and yellow food coloring
  • Pretend ice cream cones
  • Paper
  • Red pom poms


  • Measuring cup
  • Large container
  • Fork or spoon
  • Airtight container


    Start by adding two, 4 ounce bottles of Elmer's school glue to a large container.

    When it is time to dye the glue mixture, separate it into three parts and dye one brown, one pink, and the other a pale, pale yellow.

    Or, you can dye it your favorite ice cream color. We thought the Neapolitan ice cream colors were the most "authentic."

    Mix in two cups of shaving cream to the glue and stir until fully incorporated. Then, add about half a cup of laundry starch and mix.

    If your slime is still sticky to the touch, add a bit more starch until it's easy to stretch and play with. If it's stringy, just keep mixing and it will become a solid mass after about three minutes.

    Fill up the bottom of your cones with paper. This will help the slime sit on top of the cone and look more like scoops of ice cream.

    Add a cherry pom pom to the top, and play away!

    As the slime moves around, it looks like the ice cream is melting!


My kids loved playing with this and after trying all three colors of ice cream individually, they mixed them together to make real Neapolitan ice cream. Twist the colors up to make even more fun ice cream colors!
