Another frequently used gadget, the time cloth has the ability to advance or reverse time depending on which of its two different colored sides are used. When an object is wrapped around with one face outward, the flow of time reverses, causing the object to become newer. When wrapped around the other way, time moves forward, causing the object to become older. It was first used by Nobita to turn old appliances to new appliances to make money, but its uses extend to many other things, such as converting an object back to its starting material, repairing broken machinery, aging or de-aging people, and restoring millions-of-years old fossils. When picked up, of course, the holder does not age, which means the cloth is only activated upon covering an item, hence it can floating over objects with no user and still change the time of objects.
