Hi,
Dunno 'bout ping-pong balls but a tennis ball squashes beautifully at 20m
and then unsquashes as you ascend.
Take one down in an old pair of fishnet tights (um....no.. you cant borrow
mine<g>)
or if you or your OH don't wear 'em use an nylon bag that onions etc come
in.
Its fascinating to watch :-)
cheers
Carol
