A large block removed from a case magically re-appears in the case when it is opened again! You show a case containing 3 coloured blocks to your friend. One block is removed & pocketed by you and the case (now containing the remaining 2 blocks) is closed. When some magical words are uttered and the case is re-opened, the 3rd block magically re-appears inside the case! A fantastic trick for get-togethers and a great trick to perform when amongst friends. Secret instructions enclosed.
