Guys,
lets have some fun.
Which cup will fill first?
- 1
- 2
- 3
- 4
- 5
- 6
- 7
- None
- More complicated (will elaborate)

My take
- Cup 3 if water goes straight down and does not touch any of the internal walls
- Cup 7 if water touches the left internal wall
- Cup 1 if water touches the right internal wall

I meant to choose cup 6.
It’s the only path that isn’t blocked off. 
7 is sealed off
3 is sealed off
4 and 5 are as well
1 has its path blocked at the bend
2 has no path

6 is blocked off at the end lol
2 is open on top of of the tunnel where it can roll out
What I wondered was, what if the water doesn’t drop straight down at the end, and instead rolls downwards to 3 due to sticking on the surface lol
You ever pour something and it just rolls down into your hands instead of pours?
I suppose, what would matter is the speed of the water filling the tubes cuz of adhesion
If it’s a lot then 2 would get full
If it’s slow then 3 would get full

Shit, you’re right. lol
I’m full on board with your theory. It’s either 2 or 3

I have another theory lol
What if it’s an optical illusion
And all the cups are different sizes, like 1 is 10 stories tall but due to how far it is, it looks the same size as the others
And what if the same can be said about the tunnels, what if only parts of paths where close while the others where far away and really big and wide
then maybe the answer can be none, cuz what if the water would run thin by the time it even reached the end of a tube
Lol
Also, I suppose maybe, it can also be 1 if its accelerated via high pressure inside the tubes causing the water to blast through the hole on top of path #3 straight towards the tube of path #1 and down on to cup 1
Though this kind of thinking spawns infinite possibilities
Like, you can literally make up any characteristic
Like different planets gravities or outer space

If there is no rule contrary to the laws of physics here, the answer is 1. The water flowing over from the pipe of cup number 3 will fall more into cup number 1 than into cup number 2.
Because the water will accelerate with the slope of the pipe.

Maybe maybe
Also, what if there’s not enough liquid to even get to that point?
What if tube #6 takes up all the liquid
Judging by the air pocket in the container, if we say that it was full before it began to pour, then I believe it doesn’t have much liquid at all and may render filling any cup impossible
Or it would affect how much pressure the liquid has exiting the hole which would mean it may more likely go to cup 2 cuz of less propulsion
(Another crazy idea: what if the tubes are super hot and make it all evaporate lol)

I’m not sure it stays on the pipe long enough to build that momentum to reach Cup 1

If I could speak to that liquid
I would tell it
“Don’t listen to Kyle, follow your dreams, Go!

lol, yeah, but you’re assuming that’s its dream. That’s a big assumption. Maybe it doesn’t want to go to cup 1

hahaha I finally watched the answer to this question on YouTube and saw that the answer was 2🤗

I would have said this but the trajectory looks like it’ll all land between cups 1 and 2

There you have it folks

Because of the surface tension of the liquid (assuming that the poured liquid is water or tea, otherwise it depends on whether the liquid is rather cohesive or adhesive), then it all depends which internal wall the liquid is gonna touch first mostly as the liquid will follow that wall – and when it hits the bottom edge it will follow along the into the direction of that edge.
That’s why they build roofs like that, in order to avoid water running off the building’s wall:
If a roof is built poorly, then this happens:
Also for the brainiacs, consider the Jurin’s Law lol

Ohhh damn, you’re right!
I think that it also depends on how much is poured too, it would all go into the little holes first if the holes are big enough and if the pour is gentle
If it’s not gentle then the water would be spread in many directions
Now I understood your initial post lol good thinking

Actually, now I think about it and I kinda see the water falling directly down from the edge of the “roof” of the little holes and splitting both directions to meet the floor of the hole, not solely going outside of the hole
50%would go out and 50% would go in each hole the water meets after sliding down the internal wall and encountering the hole
Actually NVM
Just checked, the floor is at a slope and not flat
So it would run outside lol
But I think it would be like 70-80% going outside
If the pour is gentle enough
The droplets would split a little, with splashes on the edge of the slope as well
I like these riddles lol
