Oil Blob Dance

What You Need:

  • Clear drinking glass or plastic cup
  • 1/2 cup water
  • 1/2 cup rubbing alcohol
  • Cooking oil
  • Eyedropper

Instructions:

  1. Watch an oil blob dance between two other liquids! Here’s what to do:
  2. Pour the water into the glass.
  3. Tilt the glass slightly and slowly pour in the rubbing alcohol. Don’t shake the glass, or the two liquids will mix.
  4. Fill the eyedropper with the cooking oil and lower the tip into the layer of rubbing alcohol, but not into the water.
  5. Squeeze out a couple of drops of the oil.
  6. The oil is lighter than the water and heavier than the rubbing alcohol, so the oil blobs float between the two liquids.
