                      Science Experiment about Surface Tension

This video is a simple experiment for kids to learn about Surface Tension. This experiment is also known as ‘Run Away Pepper’. It can be done with things that can be easily found around your house.

Materials Required: –

  • Water
  • A large bowl
  • Pepper
  • Cotton swab

Procedure: –

  • Pour some water into the bowl.
  • Take some pepper and add it into the middle of the water.
  • You will be able to see a layer of pepper.
  • Now, dip the cotton swab in the dish soap and touch it to the water surface.
  • You will be amazed to watch as the pepper races across the surface instead of sinking or dissolving in the water.

Concept: –

This happens because the dishwashing liquid breaks the water’s surface tension. It allows the water to pull the pepper away from the soap.
