"Well, Raleigh was the person who introduced tobacco in England, and since he was a favorite of the queen's - Queen Bessie he used to call her - smoking caught on as a fashion in the court. I'm sure old Bess must have shared a stogie or two with Sir Walter.
Once he made a bet with her that he could measure the weight of smoke. I admit it's strange. It's almost like weighing someone's soul, but Sir Walter was a clever guy.
First he took an unsmoked cigar and he put it on a balance and weighed it. Then he lit it up. He 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."
