toad,

Light is fine. Lighter is better still.
Ingo Renner once told me a typical thermal weighed some 50 tonnes. For
the discussion, 50 tonnes or 1 gramm act the same, they are both
affected by gravity and on their own, go down like a new bride.
Bouyancy is a better way to describe the way a thermal rises and many
have pointed to the links available. Others still dont get it although
glider pilots have a higher rate so far! Hot air does not rise.

Bagger,

The mass does matter, or the thermal would accelerate faster and
achieve a higher climb rate.

Please create a complete theory of thermals, including force balance
and post it, or you are just wasting time. (that's allowed, I guess,
on the internets) Because I still have not seen a difference between
your rule and the standard thermal explanation.
