You mean, weigh smoke?
Exactly. Weigh smoke.
You can't do that. It's like weighing air.
I admit it's strange. Almost like weighing
someone's soul. But Sir Walter was a clever
guy. First, he took an unsmoked cigar and put
it on a balance and weighed it. Then he lit up
and smoked the cigar, carefully tapping the
ashes into the balance pan. When he was
finished, he put the butt into the pan along
with the ashes and weighed what was there.
Then he subtracted that number from the
original weight of the unsmoked cigar. The
difference was the weight of the smoke.
