Ingredients
  

  • Clear jar or glass mason jar or recycled jar
  • Vegetable oil or light mineral oil
  • Warm water
  • Table salt
  • Food coloring
  • Small bowl or cup
  • Teaspoon and measuring cup
  • Tray or towel optional

Method
 

  1. Pour warm water into the jar until it fills about one third.
  2. Add 3 to 4 drops of food coloring to the warm water in the jar.
  3. Slowly pour vegetable oil on top of the colored water.
  4. In a small bowl, mix a teaspoon of colored water with a pinch of salt.
  5. Use a spoon to gently drop the salt-sprinkled colored water clump onto the oil surface.
  6. Watch as the salt pulls the colored water through the oil into the lower water layer.
  7. Wait as the salt dissolves in the lower water and the colored water rises back into the oil layer.
  8. Repeat with different colors and salt amounts to create a calm dance.
  9. When you finish, set the jar on a tray and allow the layers to settle overnight.
