A husband stepped on one of those penny scales that tell you your fortune and weight and dropped in a coin.
"Listen to this," he said to his wife, showing her a small, white card. "It says I'm energetic, bright, resourceful and a great person."
"Yeah," his wife nodded, "and it has your weight wrong, too."

Helicopter

In 1877, a steam-engine driven helicopter model built by Enrico Forlanini rose 40 ft (12 m). The machine weighed 3.5 kg (7.7 lbs). Its coaxial rotors were powered by a two-cylinder steam engine. Just before takeoff the spherical steam accumlator was charged with 10 atmospheres of pressure, enabling the craft to rise and remain aloft for 20 seconds. Forlanini (1848-1930) was an Italian pioneer of scientific aviation. He built a hydroplane, which could take off on water (1905) and a new type of semirigid aircraft in1914. He also invented the hydrofoil boat. Alexander Graham Bell secured the Italian's patents to pursue his own interest in hydrofoil development.
