Sudsy Slime

You will need:

  • 1.5 cups hot water
  • Food colouring (optional)
  • 1 cup soap flakes
  • A big mixing bowl or tub
  • Electric beater or whisk

White electric beater, silver metal bowl, glass bowl with water, box of lux soap flakes and bottle of blue food colouring on brown table

 

Instructions
 

  1. Pour the water and food colouring into the bowl and mix.
     
  2. Add the soap flakes and mix with an electric beater on high until a thick foam is produced, about 5 to 10 minutes. Watch out, this foam seems to expand exponentially!

How does soap turn into slime?

Whipping the hot soapy solution creates a foam, which is a colloidal dispersion of a gas in a liquid. The gas in this case is air, and the liquid is the soapy solution. The resulting soapy foam is so dense it feels slimy to the touch! A small amount can easily fill a large tub, which makes it an inexpensive way to make mountains of it for the kids to play!
