The video shows a museum exhibit. In the foreground is a wooden model of a cart with two large wheels and a complex system of gears and wooden planks. Behind the cart, a projection on the wall displays a drawing of a mechanical device resembling a bicycle-like vehicle with a box-like structure on top and several barrels. The environment appears to be indoors, with a white ceiling and walls, and diffused lighting. There are no people visible in the video.
