WD-40 invention

In 1953, WD-40 was invented and recorded for the first time in the Rocket Chemical Company's logbook. It was the Water Displacement 40th test, and first successful, formula created by Norm Larsen, for a lubricating penetrating oil intented to displace water for rust prevention. In 1958, it was packaged in cans and sold to the consumer market in San Diego, California, where the company was founded in 1953. It was named WD-40, its original test designation. The name of the company Larsen founded reflects its original purpose to supply materials used in manufacture of nuclear missiles, for which WD-40 was designed to coat structural components and prevent corrosion. After wide success with its versatile, but only product, the company name was changed in 1969 to the WD-40 Company Inc.«

Three astronauts

Once upon a time Nasa decided to send three astronauts to space for 2 years.

NASA allowed each of them to take 200 pounds of baggage each.

The first astronaut decided to take along his wife, the second decided to take along books to learn how to speak German, while the third astronaut decided to take along cigarettes.

Two years later, when the space shuttle landed, there was a big crowd waiting to welcome them home.

First came the first astronaut and his wife and each of them had a baby in their arms.

Next, out came the second astronaut speaking fluent German.

They both gave their speeches and got a rousing applause.

Suddenly out came the third astronaut with a cigarette in his mouth.

He walked up to the podium and snarled to the crowd and asked, 'Has anyone got a friggin' match?'
