Smart kid
Bill and Marla decided that the only way to pull off a Sunday afternoon quickie with their ten-year-old son in the apartment was to send him out on the balcony and tell him to report on all the neighborhood activities.
The boy began his commentary as his parents put their plan into operation. "There's a car being towed from the parking lot," he said. "An ambulance just drove by." A few moments passed.
"Looks like the Andersons have company," he called out. "Matt's riding a new bike, and the Coopers are having sex."
Mom and Dad shot up in bed. "How do you know that?" the startled father asked.
"Their kid is standing out on the balcony too," his son replied.

Comte Hilaire ChardonnetBorn 1 May 1839; died 12 Mar 1924 at age 84.Count (Louis-Marie-) Hilaire Bernigaud Chardonnet was a French chemist and industrialist who first developed rayon, the first commonly used artificial fibre. When it was first displayed at the Paris Exposition of 1891 it was called Chardonnet silk, and caused a sensation. Although trained as a civil engineer, he went to work under Louis Pasteur. Chardonnet was prompted by Pasteur's study of diseases in silkworms to seek an artificial replacement for silk. His starting point was mulberry leaves, the food of silkworms. He turned them into a cellulose pulp with nitric and sulphuric acids and stretched it into fibres. The original fibre was highly flammable, but by 1889 he had eliminated this and developed rayon. He opened factories for its manufacture. |
