Fluffy Slime

Every Friday, I try to do a science experiment with my class. I try to make it really hands-on and fun, since this is the first taste of science they’ve ever had!

What better way to keep the kids engaged than slime?

(Slime is a serious favorite among elementary schoolers.)

This recipe is so simple, yet is a twist on the traditional slime recipe.


Fluffy Slime

Recipe from Our Best Bites. 


Borax Solution:

  • 1/4 cup hot water
  • 3/4 teaspoon borax powder
  • Optional: food coloring, glitter, mini styrofoam balls, etc.


  1. To make the borax solution, dissolve 3/4 teaspoon of borax powder in 1/4 cup of hot water (you’ll need to stir it pretty vigorously to get it to dissolve.) Add 2 tablespoons of saline solution and set aside.
  2. In a large mixing bowl, combine the glue and 1 cup water. If you’d like to add any food coloring, this is the best time (as well as any mix-ins, but you may want to wait and let kids add in whatever they want after the slime is mixed; it’s just harder to incorporate.) Mix until the glue/water mixture is completely smooth and and colors/mix-ins are evenly distributed.
  3. Add the shaving cream to the glue mixture and gently stir until combined. Add the borax/saline solution mixture and mix until combined. The boric acid/borax is what gives the slime its cohesive consistency, so you want to make sure everything is mixed evenly. When you first add it, the mixture will seize up, but as it becomes more and more incorporated into the mixture, the slime will take on an amazing, soft, fluffy, marshmallow-y consistency. If you’d like a little more firmness, you can add up to an additional tablespoon of saline solution, but start small and add a little as you go.
  4. Over time, the fluff will deflate. Store in an airtight container. Fluffy slime that is left alone in an airtight container will take on a really great, smooth, flat slime consistency after about a week.

This slime was a HUGE hit in my classroom! My students were practically shaking with joy and anticipation when I bagged up the slime for them to take home. Any kid will love making and playing with this slime!
