This afternoon I decided to make a cup of tea.  I filled my small
teakettle and turned on my electric stove, then went back to work on the
computer.  Unfortunately I twisted the wrong knob, and when I smelled
the hot metal, the element under a 3qt, flat bottomed pot was red hot.

Hmmm.  I poured a couple ounces of cold water from the teakettle into
the pot, and tipped it to swirl the water.  After a little initial
spitting, it circled around, and around, and around the pot in a long
thin puddle--more than a dozen times.  Almost like it had propulsion.
Very gradually it slowed down, got shorter and fatter, and then broke up
and disappeared in fit of spitting and sputtering.

Water droplets on a hot smooth plate will bounce around on a cushion of
steam.  But this was one big puddle of an ounce or more, 5" long and
3/4" wide.  It was fascinating!
