EFFECT: You ask a spectator for a dollar bill and have them sign it. THen sign and you take it and cover it with a hankercheif and give it back to them. Then you tell them what you are about to do. Then the dollar bill is gone from the spectator. Then out of your pocket you show a paddlocked brass tube. You have someone unlock it and upon opening it there is their signed bill!
MY THOUGHTS: It's a good trick, but not my kind of trick. But gets a good reaction. Goes for about $25.00.
