Here is a description of the video. The video shows an Archimedes screw on display outdoors in front of a modern, reflective building. Two children are operating the screws. One is a young child with a yellow hat who is looking into the box holding the water. The other child is slightly older and is turning the screw, which appears to be raising water to an elevated position. The Archimedes screw is installed in a square box filled with muddy water. The ground surrounding the box is covered with small, smooth, gray pebbles. A small plaque on the box identifies it as an Archimedes screw. Other people can be seen walking in the background. The weather appears to be overcast.
