Chinese Fireworks-800's
The Chinese were the first people to make and launch fireworks. It was thought that the first fireworks were made during the Sung Dynasty, (in the years 960-1279 A.D.) along with the invention of black powder. At first their use was to entertain, but later they used the technology for war and to ward off evil spirits. Even though these fireworks were the first self-propelled flying objects, their principle is still used in today’s modern rockets.
Leonardo Da Vinci -1400’s
Leonardo Da Vinci was an amazing artist and inventor, who also played a key role in air flight. He painted many pictures and designed many inventions, but one particular invention that has to do with air flight. This device, called the “Aerial Screw,” had a screw like propeller that was powered by four men turning cranks that rotated a shaft for flight. Scientist believe that his invention would not fly due to weight conditions, however though, his design helped make modern helicopters.
