stand by my original statement that humid air is less dense than dry air,
and this IS the correct explanation for a falling barometer. Now if Tom
or Will have actual cloud formation in their garage/basement, then Will's
explanation may be correct after all!

I don't know about cloud formations but will hot air do? Upon further thought,
I believe Len is correct. Water in vapor phase must be lighter than air and only
sinks when condensation takes place.
