Brilliant, absolutely brilliant Yukari-sama!

perpetum mobile! >D

of course they made sure yuyuko was downstream

And Yukari is eating straight out of a gap (probably filtering out some of those noodles when they fall into the gap)

Considering that the water never stops moving between the two gaps, it must be moving REALLY fast. Like falling down a giant, steep, smooth mountain.

Eh? well, if you look at the posts for the bamboo trough, it seems to be going at a fairly shallow slope. It wouldn't really go any faster than a regular Sōmen trough, I think.
