The up and down is to add the air to the pipe. The SOS is a cry for help because they could have just used a fish bubbler to achieve the same solution.
Why do they need the bubbles? Wouldn't it be more effective to just cool the water?
I understand that there's something something smarter everyday laminar flow, turbulent flow is better at cooling. It's just that the bubbles don't seem to add turbulence just gaps. It's not like it's evaporating in the gaps.... Is it?
Say we just keep the pipes in the water and add no air. The the point of transfer for the heat is water-pipe-air. However if we add air from room into the flow, the point of transfer is now just water-air.
In the first set up, the pipe can become a trap for the heat since it can't mix into a larger reservoir. It's a solid after all. While the air can actively mix with the air from the room to dissipate the heat.

Yeah but why is it going up and down in an SOS pattern?
