A professor of chemistry wante...

A professor of chemistry wanted to teach his 5th grade class a lesson about the evils of alcohol, so he produced an experiment that involved a glass of water, a glass of whiskey and two worms."Now, class. Observe closely the worms," said the professor putting a worm first into the water. The worm in the water writhed about, happy as a worm in water could be.
The second worm, he put into the whiskey. It writhed painfully, and quickly sank to the bottom, dead as a doornail.
"Now, what lesson can we derive from this experiment?" the professor asked.
Little Johnny, who naturally sits in back, raised his hand and wisely, responded...
"Drink whiskey and you won't get worms!"

Platform scale

In 1831, the first U.S. patent for a platform scale was issued to brothers Erastus and Thaddeus S. Fairbanks of St. Johnsbury, Vermont. Thaddeus invented and built it during the previous year, revolutionized weighing methods; earlier scales had been of the even-balance or steel-yard types. With the invention of the platform scale, the E. and T. Fairbanks and Company (which had until then been produced stoves, plows, forks, machines) began to specialize in manufacturing scales of all sizes. The business was successful, and grew to supply scales worldwide. On 13 Jan 1857, Thaddeus received the first U.S. patent for a railway track scale (No. 16381) which was introduced by their business. The company survives to the present day.
