What property of water molecules leads to high surface tension?

"Cohesion" is the property of water molecules that leads to high surface tension.

Surface tension is defined as the energy or the work required to increase the surface area of a liquid as a result of intermolecular forces.

In water molecules, the hydrogen ends, which are positive compared to oxygen ends, cause the water molecules to stick together, thus, increasing its surface tension.

The air is going to come out because of the low pressure.
