Science behind it
Water molecules are polar, meaning that (they are like magnets) they have negative and positive ends. 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.
