It was the kindergarten teachers birthday and the students decided that they would each buy their teacher a gift.
The first student, whose parents own a florist shop, gave her a present. She held it and said "I guess that it is flowers".
"How did you guess?" asked the little boy. She laughed and thanked him.
The second student, whose parents own a candy store, gave her a present. She held it and said, "I guess that is some candy."
"How did you guess?" asked the little boy. She again laughed and thanked him also.
The third student, whose parents own a bottle shop, gave her a box which was leaking. The teacher touched the liquid with her finger and tasted it. "Mmmmm is it wine?" she asked.

Three element vacuum tube

In 1907, the three-element vacuum tube was issued a U.S. patent to its inventor, Dr Lee de Forest as a “device for amplifying feeble electric currents - such, for example, as telephone currents” (No. 841,387). The tube was evacuated, with some remaining conducting gas molecules, and it was suggested using for the heated electrode such material as platinum, tantalum or carbon. He had made a public annoucement of his device a few months earlier, on 20 Oct 1906 at a meeting of the American Institute of Electrical Engineers held in New York City. On 18 Feb 1908, he received another patent for the grid electrode tube (No. 879,532).
