For Frank. Who needs to peer review this if it’s wrong. Superfluids are weird.
Liquid has rules: swirl, dribble and slosh
Poured into a vessel, it’s swiftly at rest
If it’s agitated, well then maybe a splosh
Is acceptable, but it is all for the best
If liquid has rules. For the way it behaves.
Predictable, sensible ripples and waves.
And then there’s superfluid.
How, does it, why does it do it?
Liquid helium, poured out and stirred
Will start climbing the wall of the glass it’s unheard of.
Breaks all of the rules. It’s counterintuitive,
Confusing. Superfluous. Absurd.
Liquid has rules.
It will stay if a cup unless tipped.
A superfluid takes us for fools
Dripping in ways that no liquid should ever have dripped.
