Archimedes Letter Scale

Archimedes Letter Scale

Droog Design, Netherlands.

The letter scale uses Archimedes's principle to weigh letters. A graduated cylinder of pyrex glass is floating in liquid. The weight of the letter pushes down the upper cylinder, thus causing the liquid to rise in between the two cylinders. The movement is thus measured and transferred into weight units.
