Two strong coin routines for casual situations where everything is examinable at the end. Show two coins and a broken rubber band. The coins are an American penny and a dime that have small holes pierced through them. Thread the penny and dime on the rubber band and have a spectator hold the two ends of the band so the coins are trapped in the center.
You then pull on the coins and let them snap back so they spin and bounce on the band. When they stop spinning only the penny is on the rubber band and the dime is found in your hand. It was seemingly plucked off the rubber band in a magical and impossible manner. Everything is examinable at the end.
