A geometric block puzzle is displayed, the assembled blocks are surrounded by a frame. The frame is removed and an extra block is removed from the performers pocket. The performer re arranges the blocks and re assembles the puzzle to incorporate the extra block! A second larger block is now introduced and the performer quickly re arranges the blocks to absorb the extra block once again! The puzzle must have increased in size? But, when the frame is place back around the puzzle it fits perfectly!
This impossible seaming effect is very easy to do when you know the clever secret. The main secret is that one of the blocks is ditched and the two blocks that you add in occupy the same space. Follow the sequence of manoeuvres as shown in the photos below and you will soon have a very baffling piece of magic to fool your audiences.
