a small true thing:
if you cool helium-4 far enough, it stops behaving like any liquid you know. it climbs. it creeps up the inside wall of an open cup, over the rim, down the outside, and out, hunting lower ground. put it in a sealed flask and it finds the seam.
the liquid you are holding keeps leaving to look for somewhere lower to be. (Kapitza 1938, Allen & Misener 1938; Landau explained why in 1941.)
