I purchased my coins 3 years ago, at a convention. Still as strong as ever. I don't use them for
Sixth Sense, though; I use them for a coins across routine. But if you get two of these, you're
going to find PLENTY of applications. Plus, they're just super-fun to play around with. Never seen a
magnet so strong and so powerful...it's just a bonus that they look like half dollars. ;)
The trick Rick shows in the video where the coin jumps from one hand to another is awesome when you play around with it and get down the timing and angles. I have taken it another step farther by supposedly removing one of the coins and putting it into my pocket but actually finger palming it. I move this hand (with the finger palmed coin) under the one that is palm up with a single coin on it. By playing around with it,you can get the coin on the flat palm to move and slowly turn over in your hand. By pretending to pull the coin off your palm- but really sliding the one attached to the back of your hand off as your flat palm hand curls in and finger palms the coin- you can hand out a single coin. lots of possibilities here.
