Highest density for water is at 39 degrees F, so your 4 must be in C.
It's life-and-death knowledge for some - particularly those who rely on
the ice-bridge to get to the mainland. Like on Mackinac Island. I know
of entire sled-loads of hay, complete with driver and team of horses,
that have been lost through the ice bridge to St. Ignace due to an
upwelling of 39-ish degree water spewing up from the bottom of the lake
and eating the ice away from beneath, silent and invisible until the
"ground" you're on literally falls out from under you.

In this case, the "pistons" are the top of the "high" water and the

Crap...really?
Figured that there would be more gravity acting on the longer sloping run of
hose that it would run out and draw up.
That's what I get for trying to think after eating cheesies! Dam them and
their preservatives!
