A little girl and boy are fighting about the differences between the sexes, and which one is better. Finally, the boy drops his pants and says, “Here’s something I have that you’ll never have!” The little girl is pretty upset by this, since it is clearly true, and runs home crying. A while later, she comes running back with a smile on her face. She drops her pants and says, “My mommy says that with one of these, I can have as many of those as I want!”
Edison patentIn 1908, Thomas A. Edison was issued a U.S. patent for an improvement to "Alkaline Storage Battery" (No. 879,612). Its purpose was to reduce foaming of the electrolyte in such batteries while in operation, which Edison attributed to the presence of even microsopic quantities of organic matter. To correct the problem, the alkaline solution, such as caustic potash, is filtered through bone black that has been first purified by washing in a hot potash solution, then washing in water.Image: plates of Edison's A-type storage battery, date unknown.
