[00:00:00]This is a very old way of building a bridge using only nine wooden pieces. It was created by Leonardo da Vinci more than 500 years ago. The design uses smart physics and simple [music] engineering to make a bridge that can stand on its own with very few materials. There are no nails, no screws, and no supports underneath. Each wooden piece is placed in a careful way so they lock into each other and stay together just because of pressure and balance. And here's the cool part, the more weight you put on it, the tighter and stronger it becomes.
