Its a great gimmick and fun! The only reason that I give it 3 stars is for the limitations on which
you can use it. Its great for a personal 1 on 1 trick, but if your gathering a crowd, the risk of
getting caught is very high! Mature audience members watch everything! And the loading of the smoke
can be easily detected by a large group with a mature nature. Still fun though, and kids love it!
I have been performing this in Starbucks stores all across the area. Mostly adults and usually several people at one time. No one has caught me, or if they have they have managed to act astounded. Maybe, the coffee group just enjoys it for the entertainment value.
