for the Weekly Prompts Weekend Challenge of 13 March 2021, superfluity.
When I first saw today’s prompt, I misread it. I thought, “Great! Finally! At last! Somebody has issued a decent physiccy prompt” and I was all set to write about superfluids.
A superfluid, by the way, is one with no viscousity. You pour it, it never stops flowing.
Life got even more interesting when I discovered that Superfluid was the name of a mascara.
And then, as if by magic, I realised that I had answered the real prompt, already!
