The faucet

Be sure to follow the rule before you head out.
Rule: You must post before you leave.
There's only one "one" in the diagram, so I'm gonna say the one marked "1." Pretty easy.
God dammit I was five minutes late
I hate you so much right now. Also I think it's 5
Yeah nothing will fill up until 5 is full. And then since 4 has a leak it, I think basically ONLY 5 will fill.
1 fills up first. the spigot is much winder than the tube so the glass will fill faster than it can drain.
Also rule
That's assuming the valve is open all the way and that there's a bunch of water pressure behind the spigot. It should be entirely possible to create a very slow trickle by having a massive body of water behind the spigot (making it functionally infinite) but having only a small part of the entrance beneath the surface.
