Magic Tricks

I couldn't believe this effect could be impromptu. But it is! No need for any thumb tip or gimmick. The effect is marvelous, as it appears in the trailer. There are several versions showed, even with bare hands, which could be ok as a quick effect. The single ring version is far the best. No need for an extra ring or gimmick. It is very well taught and as Nicholas said, it requires practice, but in my opinion, it really worth it. It is angle sensitive but can be shown to several people at a time anyway.
This effect is wonderful. I love it.
