Surface Tension in a Liquid

Materials for Experiment

  • cereal bowl
  • water
  • ground black pepper
  • liquid soap
  • a toothpick

Procedure for Experiment

  • Fill a bowl with water
  • Shake the black pepper onto the surface of the water (Notice how it stays afloat on the water? That is the surface tension holding the layer up)
  • Take a toothpick and put the end into soap so that it coats the end
  • Gently touch the surface of the water with the toothpick
  • Did you see how the pepper shoots back in all directions? What must the soap be doing to the surface tension?
  • Soap is something that actually breaks down the cohesive powers of water, making it have less surface tension.
  • If you mix some soap with water and make a water droplet on your counter again, what do you think the shape would look like? Give it a try!
