This has to be one of the coolest coin vanishes i have ever seen. It was invented by my friend Seth, who has just started getting into coin magic. He taught me this and i am in no way trying to blow this off as my own. I did the performance, but the invention goes to my friend. This can be done with any coin and is really easy! It looks really visual, even though it is quite easy to figure out. No wires thread and it didn't go on the floor. Can be done compleatly surrounded.
