Oh, so that's how a one-way valve works!

Notice that when the machine rotates the flow will reverse

And on this piece we have work from "waki", reminding the great people of Japan the importance of recycling.

It would require assisted pumping to get it from one to the other as the pressue on both would just equalise even under the one way valve. Still, an intriguing device XD

So, they're twins right? Cause they look like exactly the same person. But I'm not sure... Oh and I'd like to be one or the other, obviously, but who wouldn't?

I think this is not a torture device, as much as a revolutionary new sort of engine that makes use of women instead of cylinders.

They squeeze back and forth, and that is why the flow-paddle thingy is inverted on the top, the axis keeps spinning if they keep squeezing in and out.
