Light the World by EM Magic
Explain We are Going to Play a Game! You take a lighter that has no printing on both sides and asks a volunteer to keep it closed in his hand. Display matchboxes collected from several places around the world. Ask a player to mix the matchboxes together and throw them up in the air. The matchboxes will fall down on the table in a random order, some picture side up and some picture side down.
You'll remove from the game the matchboxes that will be picture side down. The same action is repeated until one random matchbox is left. Tell the player that the unbelievable will happen in a second so do not blink! The volunteer holding the lighter is astonished to see the name of the distant city has appeared on the lighter matches that of the final matchbox.
Show the lighter from both sides! Mechanical! Nothing to memorize!
