Surface tension is caused by a force between fluid -- measured in dynes/cm. Since it there are more forces on the surface, pushing an object surface is way harder than moving it under water.
The cohesive forces between liquid molecules are responsible for the phenomenon known as surface tension.
The molecules at the surface do not have other like molecules on all sides of them and consequently they
cohere more strongly to those directly associated with them on the surface. This forms a surface "film"
which makes it more difficult to move an object through the surface than to move it when it is completely
submersed.
Surface tension is typically measured in dynes/cm, the force in dynes required to break a film of length 1
cm. Equivalently, it can be stated as surface energy in ergs per square centimeter. Water at 20°C has a
surface tension of 72.8 dynes/cm compared to 22.3 for ethyl alcohol and 465 for mercury.
