Go to school!

Mom was trying to get her son to get out of bed and get ready for school. "I am not going to school!" the son responded defiantly.

"Why not?" Mom wanted to know.

"Well, first of all I hate school and second of all ..the kid all hate me!!" was the answer.

"Son, that's not good reasons..you will have to get up and ready for school!" Mom replied.

Dry-cell patent

In 1887, German scientist, Dr. Carl Gassner, was issued a U.S. patent (No. 373,064), the first in the U.S. for a “dry” cell. Gassner had already patented his invention in Germany (No. 37,758) on 8 Apr 1886, and also in Austria, Belgium, England, France and Hungary in the same year. The sealed zinc shell which contained all the chemicals was also the negative electrode. Later, he improved the shelf life of the battery by adding zinc chloride to the electrolyte to reduce corrosion of the zinc shell. Gassner's battery was much like the carbon-zinc, general-purpose batteries sold today. By 1896, the National Carbide Company (later Union Carbide and Eveready) produced the first consumer dry cell battery. Two years later, the company made the first D cell.«[Image: The six-inch, 1.5 volt Columbia Dry Cell marketed by NCC in 1896.]
