Two brunettes and a blonde are driving in the desert when, all of a sudden, their car breaks down.
As none of them have any motoring knowledge, they decide to walk. Each of them decides to take one thing with her.
The first brunette takes some food in case she gets hungry, the second brunette takes some water in case she gets thirsty and the blonde takes a car door.
When questioned about her choice, the blonde replies:
"Well, if I get hot, I can roll down the window!"
SandblastingIn 1870, sandblasting was patented by Benjamin Chew Tilghman (26 Oct 1821 - 1901). Compressed air forces sand as an abrasive material through the nozzle of a sandblasting gun. A popular myth holds that Tilghman, when a General in the army, had seen the effect of wind blown sand upon glass windows, in the desert. The sand has etched the glass where unprotected and revealed the contrast against parts that were covered by steel mesh. He has been called the "father of shotpeening." In 1866, he found sulphurous acid would dissolve the intercellular matter of wood, freeing the fibres for pulp, and became famous as the inventor of the sulphite process to make wood pulp for paper production. |
