The EDU-61003 Leonardo da Vinci Swing Bridge design is a portable, lightweight bridge that was intended to span across a body of water so armies could cross and then quickly disassemble and tow away. By means of an articulated system of winches and wheels, the bridge was designed to rotate 90 degrees... The scientific genius of Leonardo da Vinci is brought to life through this articulated model. The invention that inspired this snap-together replica is taken from the pages of Da Vinci’s priceless and awe-inspiring notebooks. All models are made of plastic and require no special tools. Manuals are very educational and teach how these inventions have evolved into what they are today.
