A tour bus driver is driving with a bus load of seniors down a highway when he is tapped on his shoulder by a little old lady. She offers him a handful of peanuts, which he gratefully munches up. After about 15 minutes, she taps him on his shoulder again and she hands him another handful of peanuts. She repeats this gesture about five more times. When she is about to hand him another batch again he asks the little old lady, " Why then don't you eat the peanuts yourself?".
"We can't chew them because we've no teeth," she replied.
The puzzled driver asks, "Why do you buy them then?"
The old lady replied, "We just love the chocolate around them."
Guncotton patentIn 1846, Christian Frederick Schönbein of Basle, Switzerland, was issued a U.S. Patent for guncotton titled “Improvement in Preparation of Cotton-Wool and Other Substances as Substitutes for Gunpowder”(No. 4874). The process uses a mixture of concentrated acids to convert the cellulose present in well-cleaned cotton-wool, C6H10O5 into cellulose nitrate C6H8(NO2)2O5 (nitrocellulose). In 1891, James Dewar and Frederick Abel incorporated nitrocellulose in a mixture that could be handled more safely. Until WW II, this invention replaced gunpower on the battlefield, where it had been used for five centuries. It was also useful for blasting because it generates about six times the gas of an equal volume of gunpowder and produces less smoke and heat.
