Back in the seventeenth century, scientist Robert Boyle devised
a perpetual motion machine that he claimed would enable a flask
to refill itself ad infinitum. It didn't work. But in this video
by Munchausen Today (who "publishes videos created on pseudo-
scientific beliefs, unproven facts, false evidences, not-
patented inventions and my own crazy ideas"), Boyle's
thermodynamically impossible device is finally realized. With
beer.  FYFD explains:  The concept was that capillary action,
which creates the meniscus of liquid seen in containers and is
responsible for the flow of water from a tree's roots upward
against gravity, would allow the thin side of the flask to draw
fluid up and refill the cup side. In reality, this is not
possible because surface tension will hold it in a droplet at
the end of the tube rather than letting it fall. In the video
above, the hydrostatic equation is used to suggest that the
device works with carbonated beverages (it doesn't; the video's
apparatus has a hidden pump) because the
