Dynamic Fluids

Scenario: While washing dishes, you come across a 1.5 pint glass previously liberated from a national chain brewery/restaurant.

The glass is slightly less than half full of water. In order to swab out the bottom, you tilt the glass and push the soapy sponge forcefully into the bottom of the glass.

Applying your knowledge of the principles of displacement, does the water:

A.) Compress into a small mass at the bottom of the glass.

B.) Maintain surface tension and flow down the outside of the glass, down the drain.

C.) Jet forth from the mouth of the glass, soak your shirt and puddle down onto the floor.

Bonus Credit: Prior to washing, what liquid did the glass previously consume? Explain your reasoning.
