Water is much more attracted to itself then the air.  It seems like water can  form a skin on the surface . If you put a needle on the surface of a bowl of water it floats  but if you throw it, it will sink.  This means the surface of water does not want to break. If you fill a cup to the brim , as the surface of the water will hold together and resisting a spill
