Wand And Block, Natural by Daytona Magic (M11)

A wand is placed through a hole in a block. After this is done a few times the wand disappears by about 80% into the block. The wand is now extracted from the block and is restored to its original length. The spectators actually see the wand melting into the block. It is a very baffling illusion, yet with this mechanical device it is very easy to do.
