I think the guys above are right, it's an incredibly visual and magical looking effect, but it's not the kinda thing you can carry to do walkabout or off the cuff.
You know what though? I wouldn't want to.
There are certain effects that I save for certain situations, a. when it's possible to achieve the effect to it's fullest and b. when there's the opportunity to get a lot out of the performance.
This is the kind of effect I would save for those occasions that you REALLY need to make an impression, it's the kind of effect that will allow the MYTH to build around you as people.will.talk.
It's very easy to burst a REALLY powerful story by performing the same effect with less impact, it immediately crushes the thoughts of amazement and wonder that has been created from hearing a story about you.
So learn the effect, practice and save it for that special occasion that you know you can get the most out of it and when the situation is correct.
