Soap slime is an easy-to-make type of slime that is fun to play with and makes clean-up fun. Here’s how you make it.

Soap Slime Materials

  • leftover pieces from bars of soap (or you can use a whole bar)
  • water
  • jar

Make Soap Slime

You’ve probably made soap slime accidentally by allowing soap to get wet and stay wet in the bathtub or shower. Here’s how you make soap slime, on purpose:

  1. Place the soap pieces in a jar.
  2. Cover the soap with water.
  3. Let the jar sit for a day or two. You’ve got slime!

You can play with the slime or you can use it during bath time like you would ordinary soap. The soap slime with rinse away with water. Soap isn’t edible, so don’t eat this slime either. Also keep it out of your eyes. If you get some soap slime in your eyes, immediately rinse it out with water. Otherwise, have good clean fun!

Make Dish Soap Slime

Another cool type of soap slime to make uses dish soap. The ingredients for this slime are:

  • liquid dish soap (choose the color you want the slime to be)
  • glitter
  • clear non-toxic glue (PVA or polyvinyl alcohol school glue)
  • salt water or saline solution (although you’ll get better results using borax in water)

Soap in a tube? Why not! Typically when people make soap, they make a lot of it. However, you can make a small amount of soap in a test tube as a chemistry demonstration. This is a terrific example of the saponification reaction, plus it results in a product you can use.

Soap Materials

  • sodium carbonate (a home canning chemical)
  • calcium oxide (used to control humidity, sold in home stores)
  • sodium chloride (table salt)
  • butter or lard
  • water
  • 2 test tubes (or small heat-safe cups, if you don’t have test tubes)
  • candle or alcohol lamp
  • teaspoon or other measure

Make Soap in a Tube

  1. Add two scoops of sodium carbonate and 3 scoops of calcium oxide into a test tube.

  2. Fill the test tube about 3/4 full with water.
  3. Heat the test tube in the flame, but don’t bring the solution to the boiling point. As a safety measure, point the open end of the test tube away from your face. This is a good lab practice when heating any chemicals.
  4. Remove the test tube from heat and allow it to cool.
  5. When the liquid has cleared, add a pea-sized amount of butter or lard.
  6. Return the test tube to the flame. First, the butter or lard will melt. When it starts to mix with the water, add 6 scoops of sodium chloride.
  7. Carefully shake the test tube to mix the ingredients. The soap will rise to the top of the test tube.
  8. Allow the tube to cool and then remove the soap. If you rub it between your fingers, you’ll feel the characteristic slippery texture of your creation.
