Where, when, and why was tin foil invented?
Oh, I see. That makes sense. Did it take long for tin foil to become popular for other uses besides food packaging?
It actually didn't take too long for tin foil to be used for other purposes. In the 1920s, it became popular for wrapping cigarettes to keep them fresh, and in the 1930s, it started to be used for insulation in aircraft.
