The answer for Amazing Drop of water as below; Molecules of water attract each other with a very strong force. Hence you have the surface tension and the forming of a spherical drop. It takes some time for the gravitational force to weigh down the force that keeps the molecules of water drop? together. There's no immediate interaction in physics.
In addition, the drop of water touches the surface over very small area, so the intermolecular forces are weak at first. When the gravity enlarges that area enough, both forces are strong enough to? break the drop.
That's the explanation. No "air layer" conjecture is needed.
