Leonardo da Vinci was a renaissance man – a man of many talents. He gave us the Mona Lisa and the Last Supper, but he also sketched machines from the future. For example, he sketched the helicopter.
People turned his drawings into 3D models and the models are now on display in the Science Museum in London this month. You can see many interesting models there, including a 15th century diving suit designed for sabotaging enemy ships.
Difficult words: sketch (to draw quickly), sabotage (to destroy).
