Leonardo da Vinci was an Italian inventor and came up with many great ideas that was way ahead of his time. Some of his inventions and ideas were the bicycle, water pumps, a self supporting bridge, a tank, a parachute, a 33-barreled organ and an anemometer. He also came up with som flying machines like the helicopter. It was very different from a modern helicopter but worked the same way. By taking air and pushing it downward. Sadly, it was never built and wouldn't be able to fly either because of the weight. To honour his great mind I made this lego model of the helicopter and hope it will inspire people to think of new ideas and also learn more about physics.
