This is a wonderful effect, both clever and mind-boggling for a spectator. It's advertized as
requiring no sleight of hand, which isn't true. There is a sleight and it takes practice to get it
to be reliable as well as quick. I am still working on it. You also have to be able to do a simple
calculation, also quickly. Neither obstacle is a deal-breaker. This effect will go into my
repertoire very soon!
