Thus a bit of fun can be had with something like a piano that is
beyond its useful life. You end up with a pile of small bits which are
then easy to dispose of.

Just don't try smashing a piano unless all the strings have been
slackened off first -- the force across a piano frame is very
large and presents a serious hazard if you are just going to
lay into the thing with a hammer or similar...
