Here's an old puzzler from my high school science days, but which may
tantalize a few of you:

When an ordinary mercury thermometer at room temperature is inserted
into a beaker of boiling water, the mercury actually descends a
small but noticeable amount before ascending to the 100 C level.
Why?

Try it yourself.
