When I was in the Scouts many years ago we used to get them given
to us for jumble sales - inevitably they didn't sell so we had
piano smashing competitions - to see which team could post the
piano through a 1foot square hole (IIRC). The frames would break
with a sledge hammer. The piano wire was a pest.
Smashing a piano can be quite dangerous without making it
safe first (releasing the tension on the strings). There's
around 25 tons force across the frame, and you don't want
that to let go in one bang by breaking the frame.
Even individual wires breaking can cause nasty injuries.

I broke one up as a teenager and there might be 25 tons of force but
it was not that dramatic when hit with a sedge hammer, 25 tons of
force with elastic bungy rope might be a different kettle of fish,
and after watching mythbusters snapping 1/4 steel wire even that was
not that dangerous
exactly

but it might be as well to loosen the strings first

all 200 of them ?
not counted them, that's was just my get out of jail free card :-)


88 * 3 - bass strings , round off to the nearest sensible number
