They're actually attracted … WebCapillarity—Measuring Surface Tension. Students are presented with a short lesson on the difference between cohesive forces (the forces that hold water molecules together and create surface tension) and adhesive forces (the forces that causes water to "stick" to solid surfaces. Students are also introduced to examples of capillary action...

Because of the relatively high attraction of water molecules to each other through a web of hydrogen bonds, water has a higher surface tension (72.8 millinewtons (mN) per meter at 20 °C) than most other liquids. Surface tension is an important factor in the phenomenon of capillarity. Meer weergeven Surface tension is the tendency of liquid surfaces at rest to shrink into the minimum surface area possible.
