This causes water molecules to be very attracted to each other. If you remember when I placed drops on a penny, the force of attraction between the molecules overcomes the force of gravity and the water builds up like a dome on the penny. I think I was able to put 30 drops of water on the penny. The same thing happens in the glass, with the surface changing from flat at the rim to a rounded dome on top, and at some point if you have enough paperclips the water will break its surface tension and spill out. Water is a polar molecule. The oxygen side of the molecule has a partially negative charge The hydrogens, on the other side, have a partially positive charge. As a result, water molecules form hydrogen bonds, interacting as shown with the dome on top of the glass of water. When molecules bond its called Cohesion and there is a lot of Cohesion in water.
