All around the world inventors are creating new things.For example,the Wright Brothers.They created the first airplane.They did this by making a fabric covered biplane with a wooden frame. The power to the two propellers was supplied by a 12-horsepower water-engine.On December 17, 1903 the "Flyer" flew for 12 seconds and for a distance of 120 feet.The flight took place at kitty Hawk, North Carolina, USA.
Another invention is the windshield wiper, made by Mary Anderson. In 1903 to help cars operate safely in the rain.In 1905 she patented her invention, which allowed the car operator to control the external swinging arm wipers from within the car.Windshield wipers became standard equipment on cars a decade later.
A invention you might not know about is the Water Screw a Greek mathematician named Archimedes made the devise for raising water using an encased screw open at both ends.The screw is set in an angle, and as the screw turns, water fills the air pockets and is transported upwards.The screw is still being used today.
