The magician takes a black ball from the vase and vanishes it. On command of the magician, when the lid of the vase is removed, the black ball is again found inside and can be removed. This ball vase is rather unusual in that it has a thread through the bottom half of the vase. If you pull on the thread, it lifts the bottom part of the ball out, so avoiding it getting stuck. Once the possession of Cambridge magician Claude Perry.
