Did you know that men learned how to make paper by observing paper wasps? Isn't that amazing!?
"Around A.D. 105 a Chinese court official named Ts'ai Lun observed paper wasps making a next. He experimented with mulberry bark, hemp, and rags with water, mashing various mixtures into a pulp, pressed out the liquid and hanging the thin mats up to dry.
Tree bark or bamboo was a typical source of paper in China. In Europe, linnen and cotton rags were often used.
In both cases, the fibers were beaten in water to make a pulp."
