A fellow bought a new Mercedes...

A fellow bought a new Mercedes and was out on the interstate for a nice evening drive. The top was down, the breeze was blowing through what was left of his hair and he decided to open her up. As the needle jumped up to 80 mph, he suddenly saw flashing red and blue lights behind him. "There's no way they can catch a Mercedes," he thought to himself and opened her up further. The needle hit 90, 100.... Then the reality of the situation hit him. "What am I doing?" he thought and pulled over. The cop came up to him, took his license without a word and examined it and the car. "It's been a long day, this is the end of my shift and it's Friday the 13th. I don't feel like more paperwork, so if you can give me an excuse for your driving that I haven't heard before, you can go."
The guy thinks for a second and says, "Last week my wife ran off with a cop. I was afraid you were trying to give her back!"
"Have a nice weekend," said the officer.

Illuminating gas

In 1875, inventor and scientist, Professor Thaddeus S.C. Lowe (1832-1913) patented a process for water gas production of "illuminating or heating gas." This gas making process fundamentally consists of the spraying of oil into water gas (blue gas) in a hot vessel for the purpose of increasing the calorific value of the gas. This carbureted water gas process was soon the most important manufactured gas in the United States of its time. He later invented a number of important and basic devices for use in atmospheric observation and metallurgical processing. Earlier, during the Civil War, he had created a military balloon force to spy on Confederate troops.
