Black Powder

A guy enters a bank to see about getting a business loan.
"What kind of business do you want to start?" asks the bank manager.
"I have some black powder. You sprinkle it on a women's vagina and it makes it taste like a peach."
"I don't think we can give you a loan." he replied.
So the guy left. A few months later he went into the bank with a wheel barrel filled with money.
The same bank manager said, "Congratulations, I guess that idea for black powder really paid off."
"Nah, that didn't go anywhere. I made my money with this white powder."
"Really," replied the bank manager. "What does it do?"
"Give me a peach and I'll show you."

Dirigible

In 1852, a new invention, the dirigible - a semi-rigid airship - was demonstrated in a flight from Paris to Trappe. Henri Giffard (1825-82) installed a small (3 h.p.) steam engine of his own design in the gondola of a 147-foot-long spindle shaped coal-gas balloon. This engine turned a 11 ft propeller producing a speed of 5 mph against the wind over a distance of 17 mile on a 3 hour trip. This was the first powered and controlled flight ever achieved. (In 1858 he patented a steam injector which became widely used in locomotives, making him rich. Nevertheless, Giffard was depressive and died by suicide in 1882, but left his fortune for humanitarian and scientific purposes.)
