Since I have just discovered that our 'weighing air using two
balloons and
a meter stick' experiment isn't accurate (apparently it only shows
that
air under pressure weighs more than air that isn't), does anyone
know of
any simple experiments/demonstrations that can show kids that air
has
weight? Or is it something we have to take on faith?
Thanks for your help-- I know my requests aren't for the usual
'deep'
topics discussed on the list, but I really do appreciate it.
