I'm not sure why it's called that, but I think it might be because the
shadow narrows down and almost appears to "twist" before going
back to the original shape ..... The article we found it in talked mostly
about shadows and bright bands on the bottom of a pool, and included this
as well as the shadow of a vertically held pencil with the tip submerged
- interesting effect there if only slightly submerged .... I hadn't seen
it before and I thought others might be interested.

Well,
Roger, I can see a break in the thermometer's shadow where it penetrates
the interface, but I'm damned if I can see a sausage.
Is it supposed to be like the
"sausage" you see when you bring two fingers together in front
of your face?
