A needle is pushed straight through the center of an ordinary box of matches. Immediately after the needle is pulled right through the box every thing is handed to the spectator. To his amazement, the box is completely filled with a solid block of brass.

Absolutely everything may now be examined and the spectator will have no clue as to how the penetration occurred. Nothing added or taken away. No switches. Absolutely no sleight of hand whatsoever. The ingenious hidden mechanism does all of the work for you. Precision engineering at its very best.
