Coin Scan (Be a metal detector)
Someone selects a coin and holds it in their closed hand. You use your iPhone as a metal detector and scan their hand. Your iPhone correctly guesses the coin!
Works with USA coins and Euro coins. Written and video instruction.
A very cool coin magic trick!
"After reading the instructions, I enjoyed toying with my wife. She is still trying to figure out how it works. …for an occasional party trick it's a good choice."
