Surface tension
A measure of how difficult it is to stretch or break the surface of a liquid. Between the water and the air exists hydrogen-bonded to one another and to water below, making the water seem like it is coated with an invisible film. This can be observed by slightly overfilling a drinking glass; the water will stand above the rim without spilling.
The molecules of a liquid attract each other. The interactions of a molecule in the bulk of a liquid are balanced by an equal attractive force in all directions.
1 - The ring is above the surface and the force is zeroed.
2 - The ring hits the surface and there is a slight positive force due to the adhesive force between ring and surface.
3 - The ring must be pushed through the surface (due to the surface tension) which causes a small negative force.
4 - The ring breaks through the surface and a small positive force is measured due to the supporting wires of the ring.
5 - When lifted through the surface the measured force starts to increase.
6 - The force keeps increasing until
7 - The maximum force is reached
8 - After the maximum there is a small decrease of in the force until the lamella breaks.
Surface tension of water.
Attachment doesnt sink becouse of surface tension of water.
Hair on water, surface tension effects. The hair is supported on the surface of the water by the surface tension. Lighting effects and filters have produced the colours seen here.
This sportive likes water tension... becouse of water tension he/she slides on water....

He doesnt like surface tension...becouse of surface tension, he can be injured...

Surface tension plays a big role in many of our daily activities. Soaps and detergents include surfactants, that reduce the surface tension of the liquid. This allows the liquid to have a good contact with the material and to remove the dirt from it efficiently.
Ebru (Marbelling) is possible becouse of surface tension
Another sample for surface tension...

Nope! I couldn't do it :( My money sank each time i tried!
yasemin you can always observe it.
if you want to float attach on the water you must put it on the water very slowly and quitely...
it is always possible but if you put a wet attach surface tension pulls it in the water....
I think some conditions must be required for surface tension. Does it work everytime? Hmmm, I don't think so. Maybe speed, weight, temperature etc. are important. I tried to do this but failed.
