A teacher was giving a lesson...

A teacher was giving a lesson on the circulation of the blood. Trying to make the matter clearer, she said, "Now, class, if I stood on my head, the blood, as you know, would run into it, and I would turn red in the face.."
"Yes," the class said.
"Then why is it that while I am standing upright in the ordinary position the blood doesn't run into my feet?"
A little fellow shouted,
"Cause your feet ain't empty."

Life preserver

In 1841, the first patent for a U.S. life preserver of cork was issued to Napoleon E. Guerin of New York City (No. 2,359) for his "Improvement in Buoyant Dresses or Life-Preservers." It was of the form of a jacket or waistcoat. The jacket was described as being made from a doubled layer of material, with sufficient room for the introduction of from 18 to 20 quarts of rasped or grated cork. After the insertion of the rasped or grated cork between the layers, those parts of the garment left open would be sewn closed. The difference in quantity of cork was chosen according to the size of the person for whom the life preserver is to be made.*
