Davenports Red and Green Tube
This is a colour changing trick. The magician shows a red handkerchief and pushes it into an empty green tube, which is next wrapped in newspaper. The magician then reaches into the covered tube and removes the handkerchief, which is now green. The tube is removed from the newspaper and now it has turned red. The red tube can again be shown to be empty. The inside of the metal tube is stamped with a Davenports demon head.
