Men knew how to make kites hundreds of years ago. Kites could stay in the air for many hours. “if birds and kites can stay up in the air, perhaps we can too," They thought.
At first they made wings like wings of birds. They jumped off high buildings and tried to fly. Many men did this but they all failed in their effort. They fell down on to the ground. Some were dilled and some were badly hurt, wholesale coach handbags. After many times they stopped trying to fly with wings. Then two brothers tried another way. They tried balloons. “hot air is lighter than cold air,” they said.” that’s why not air goes upwards. If we fill a balloon with hot air, it will go upwards.”
They built a balloon. It was made of thin cloth and paper, wholesale designer handbags. They lit a fire under it . up into the air it went . it reached a height of 1,800 meters. Then the air inside the balloon became cool and it came down slowly and gently landed on the ground.
