What is surface tension?

Surface tension is the tendency of liquid molecules to stick to each other. This causes water to cling when it spills down the outside of a glass. Try it in your kitchen sink. Take any glass, turn it on its side and put it under the faucet. Now turn the water on. No matter how fast the water flows from the faucet, nearly all of it clings to the sides and bottom of the glass.

Gutter Helmet's innovative nose-forward design relies on the physical law of surface tension. Improvements in the ribbed design and wettable coating offer greater surface tension than ever before.
