P.S.: On a much lighter note, an old friend swears up and down that you
can
prevent a recently dropped soda can from fizzing over by inverting it and
rapping it once, sharply on a firm surface--such as the floor or a table.
From time to time, he asks if I've tried it; and I claim that didn't drop
a
soda for a while and then forgot. This ritual has continued for years.

Funny!

You can "knock the fizz back down" by tapping on the top with your
fingernails, or another small object, 10 or 15 times.
