Snow day Slime: 4 ingredients & no borax

Making slime, whether you’re 50 or 5 years old, is always fun! Kids can make it with only a small amount of help from us adults. Slime is quick to prepare, easy to clean up, and fun for hours. My kids categorize it as “not a solid, but not a liquid”, “so stretchy,” and “super sticky.”

On a recent snowy day when school was canceled and we were worn out from playing outside, we had a blast making this borax-free version of slime with ingredients that are readily on-hand at home.


  • Elmer’s glue (preferably the clear version, but can be white)
  • food coloring
  • baking soda
  • saline solution (if you don’t have saline solution, add 1/2 tsp of fine salt into 1 c hot water, stir until dissolved, and cool)


  1. Add 4-8 oz of glue to a glass or plastic bowl
  2. Add a few drops of food coloring and mix with spoon
  3. Add 1 tsp of baking soda and mix
  4. Add 2-4 tbsp saline solution and mix until slime forms a ball that is slightly sticky, but won’t stay stuck to hands
  5. As slime is played with, add more saline solution as necessary to prevent it from getting too sticky
  6. Store slime in sealed plastic bag or container to preserve it

Observations and Experiments:

  • How does slime feel before and after saline solution is added?
  • How far can we stretch slime?
  • What happens if we pull slime apart with force instead of slowly stretch slime?
  • What shapes can we make with slime?
  • What surfaces does slime stick to?
  • Does slime bounce?
  • What happens to the surface of slime when we mold it to our palm?

Enjoy cultivating your and your children’s curiosity making and exploring slime!
