Question

Why does a stream of water from a faucet become narrower as it falls?

Answer 1

Answer:

The answer is simple: Gravity. Like all objects, a stream of water also accelerates as it falls. Since the density of water is a constant, and water tends to hold together (cohesion), the only thing that can happen is the narrowing of the stream -- which is exactly what happens.
