"G"
For long live physics

@peterlhawks

Option G has narrow height for the tubes and floor. Hence, it will flow instantly in seconds, compared to the ones with the tubes that are wide in length and height.

@Matick125

It has to be G
And here’s why:

A- will constantly be emptied out
B - the same as A
C - same as A and B
D - also would be emptied out because of the tube bellow
E - need to wait for D to fill up so the tube itself can be filled up, and for the tube to fill up G would already have to be filled up
F - the whole tube would have to be filled up, and for that H would already have to be filled up as well
G - is close to the start and has a directo tube, not one where the water would have to rise and fill up the tube, it would just be a constant water flow
H - tube’s too long, would take a lot of water for it just to start reaching H, and something else would already fill up before
I - it would be the last one to fill up am sure (without the starting ones who begin the entire thing ofc) since J would need to fill up enough to reach I, but before it would reach L and empty out below
J - it would be emptied out very quickly since it is the one responsible to fill up L H and F
K - K would require I to start getting water, which would only happen after J gets filled up, and also after LH and F are filled up too
L - would constantly be drained to fill up H and F

"G"
took me less than 3 seconds lol, i just follow the water with the lowest pipe.

@Ryan-xh7pe

Def G, C will empty out equally from both sides and G is the closest “dead end” for the water after that

@sebastianduke9715

G: the pipes directing to G are lower than the others so water will go first there and it only has a few tanks to get to G

@kingbugszy

"G" seems to be the most reasonable to me.

@escher9622

G
When the water gets to C, it will evenly distribute to J and D. J will not begin to distribute water to another spot till it's halfway filled. D will distribute every drop to G immediately, making it fill the quickest.

@papyrus_52

G, finally physics class worked for something

@thebigcruzzmeister9286

I reckon it is “G” what do u guys think?

@prax-alittlecrazy2422

“G”
It seems most logical as I will take time to fill up.

@real_jxsh

People who chose “H”, which has no openings: 
My goals are beyond your understanding

@anything-1228

its "G" obviously...it makes more sense

@unknownymous4855

my man newton told me before that G was for gravity

@psygamez7727

It’s g, j is either higher or the same to d but either way g doesn’t have an exit so it has to be g

@tigerteamsquad

"G: because if the water is dripping slowly then it will always go to the container with the lowest pipe.

@speeedslayer

It's definitely G !!

@mrcavafy

I just randomly said G for some reason…

@gklb_2xx7

despite this puzzle being years old, there is still excitement with solving it

@AA-100

The original version has Tank C blocked off from the right side so water cant flow into D, but in this version since it isnt blocked, G is the answer
