The Hidden Science of Surface Tension in Water

  1. Invisible Skin: Surface tension acts like a stretchy film across the top of water.
  2. Molecular Grip: Water molecules pull on each other tightly through cohesion.
  3. Hydrogen Bonds: These tiny attractions between molecules create strong surface effects.
  4. Droplet Shape: Surface tension pulls water into round beads instead of flat puddles.
  5. Bug Trick: Water striders walk on ponds because their weight doesn’t break the surface.
  6. Floating Objects: Even a paperclip can rest on water if placed gently, thanks to tension.
  7. Capillary Action: Surface tension helps pull water up plant stems through tiny tubes.
  8. Soap’s Secret: Soap lowers surface tension, letting water spread and clean better.
  9. Everyday Example: The dome shape of water in an overfilled glass shows tension at work.
  10. Life Link: Surface tension is vital for raindrop formation and many natural processes.
