<DIV><FONT color=#000000 size=2>I confess that I haven't actually =
done this, but
consider taking a handful of jack springs and squashing them into a =
small jar
containing hydrochloric acid (let 'em know whose the boss). =
Somehow screw
on the lid without the little beasties springing back out and splashing =
the acid
over your hands. Observe the springs being slowly dissolved away =
by the
acid. </FONT></DIV>

<DIV><FONT color=#000000 size=2>Question (which I'm not entirely =
sure what the
answer is): Where does the potential energy go that was contained =
in the
squashed springs? Newton said that energy must go somewhere, but =
in this
case - where? Brian Holden, BSc and piano tuner NZ.
