May Days of Melies - The Man with the India Rubber Head [L'homme à la tête en caoutchouc] (1901)

Méliès unveils a new trick in The Man with the India Rubber Head (aka L'homme à la tête en caoutchouc). A scientist (mad?) brings forth a living head he's been storing in a box; a head that happens to be identical to the scientist (a clone?). Méliès then begins the new magic by blowing up the head, first with an expansion/contraction, and then literally.
