Nose weight

[Bob Richards]

I knew it would weigh negative. However, doing that
just tells you how much LESS it weighs relative to
air.

I guess the only real way to weigh it would be to
completely evacuate a tank (perfect vacuum?), weigh
that, then fill the tank (atmospheric pressure only)
with helium and weigh that.

Talk about subject drift!!!
