The magicians wand dematerializes as it enters a block of wood containing strange powers.
Performer picks up a 15 inch wand and shows that it freely slides through a hole and a block of wood. When the powers are activated, the Wand slowly dematerializes, shrinking down to 1/3 of its original size.
Reverse activation returns the wand to its original self.
Easy to do. Fun illusion.
