The cotton gin - an infamous invention

Unfolded Physics on Instagram: "The hand crank cotton gin shown in the video uses simple mechanical motion to separate cotton fibers from their seeds. As the crank turns, fibers are pulled through narrow slots while the larger seeds are held back, completing in seconds what once took much longer by hand. Before machines like this, removing seeds from cotton was slow and labor intensive, often done fiber by fiber. Early cotton gins dramatically increased efficiency, allowing farmers to process fa
