[[Cueball]] and [[Megan]] have set up a simple experiment to test how a {{w|siphon}} works, using the gravitational force on a lower portion of liquid-filled tube, atmospheric pressure on the upper reservoir, and molecular cohesion within the liquid, to move a liquid upwards through a bit of tube at a higher gravitational potential. In short, the liquid passes over a higher peak to reach a lower exit. [[Randall]] has also mentioned siphons in [https://what-if.xkcd.com/143/ whatif 143] and in his book, "[[How To]]," section "How to Throw a Pool Party". | [[Cueball]] and [[Megan]] have set up a simple experiment to test how a {{w|siphon}} works, using the gravitational force on a lower portion of liquid-filled tube, atmospheric pressure on the upper reservoir, and molecular cohesion within the liquid, to move a liquid upwards through a bit of tube at a higher gravitational potential.

Apparently, even though Cueball and Megan have set up the experiment correctly, the water no longer demonstrates a siphon by flowing from the upper bucket to the lower. Cueball observes in surprise that "it's true," that siphoning doesn't work anymore. Thus indicating that this is a very recent development, and Megan remarks that it was honestly weird that it ever worked, and muses over why we ever thought that was a normal thing. | Apparently, even though Cueball and Megan have set up the experiment correctly, the water no longer demonstrates a siphon by flowing from the upper bucket to the lower.
