oil is denser than water, it breaks the surface tension because it is another liquid with a higher density. we dont break the surface tension because we are a solid. the oil is a liquid... look at a lava lampp for example, it has oil and water but the oil is constantly moving upward because it has a hgiher density- the heat causes it to rise and the density causes it to sink. so oil with slip right through water destroying the surface tension
Oil is NOT denser than water. Oil is less dense than water which is why oil floats on water. This makes your answer completely incorrect.

What liquid does gold float on?
Gold can float on water if there's a layer of oil on the surface. To break the surface tension, a drop of Dawn soap will do the trick.
Does cooking oil have more surface tension than water?
Because of the polarity of the water molecule, hydrogen bonds form between them. This results in the higher surface tension. Oil is nonpolar, so hydrogen bonds do not form between the molecules, so the surface tension is less.
Why does oil in a bowl of water get repelled when washing liquid is dropped on it?
The oil is not repelled. It is floating on the surface of the water as a thin film. Water has very high surface tension, but when soap or detergent is added to water that surface tension suddenly drops. The water surface now contracts like a punctured rubber sheet toward the remaining area of high surface tension, dragging the oil film floating on its surface with it.
Does vegetable oil have more surface tension than water?
No. Vegetable oil's surface tension is approximately 34 dynes/cm while ultrafiltrated water is 72.40 dynes/cm.
Why does water have higher surface tension than oil?

How are small insects able to walk on the surface of water?
The oil on their feet is strong enough to repel the water and there weight is spread out enough that when their feet touch the water, the oil and the water repel each other like when you pour oil on water the oil floats on the top... same principle
How can you test how much weight the surface tension of water can hold?
Small insects such can walk on water because their weight is not enough to penetrate the surface. A carefully placed small needle can be made to float on the surface of water even though it is several times as dense as water. If the surface is agitated to break up the surface tension, needle will quickly sink.
Why does a drop of water placed on the surface of oil contracts to form a spherical shape?
The surface tension of the water and the fact that oil and water cannot wet each other.
Why mosquito float on the surface of water?
Due to the property of surface tension water surface would act as a stretched membrane. So water skaters, mosquitoes could easily walk on the surface. If oil is mixed with water then surface tension would fall and mosquito cannot breed. That is why we sprinkle oil in fine droplets on stagnant water
What can be done to get water out from under the oil level in the compressor?
Perform a deep vacuum and vibrate the compressor casing to break the surface tension of the oil. Or you can simply apply heat to the bottom so that the water boils off and the vapor is removed by the vacuum.
How doe soap make it possible for water and oil to mix?
The chemical properties in soap break apart the surface tension of water which doesn't allow water and oil to mix. When you add the soap, the two liquids mix homogeneously.
