The Great Match Box Illusion by Magic Makers

Match Box Magic Trick - The Great Illusion

Remove a matchbox from your pocket and a toothpick. Push the toothpick straight through the center of the box freely showing all sides with nothing to hide. Remove the toothpick and open the box. What they see is a solid heavy block that entirely fills the box! The solid heavy block can be examined.

No skill required.
No sleight of hand.
A self-working miracle.
