The Weight of Handwriting

Click to enlarge. From The Outline of Science, 1922. One of these would be useful for determining exactly how much weight you gained over Thanksgiving.

I'd guess that one could use something a bit less sensitive. Something like this, maybe:

I actually used one of those back in the 1980's. It was sensitive to 0.1 milligrams, (1/250,000th of an ounce) but was VERY tedious to use. There is a bubble level to get it as level as possible, and a sliding glass door to keep your breath off the balance. The brass weights have to be handled with tweezers and tongs so you don't get fingerprints on them - fingerprints have weight, too.
It took about 15-30 minutes to make a single weighing, and the scale couldn't weigh anything heavier than about 5 kilograms (11 pounds).
