I have been doing a trick for a year now where I do a coin trick while pickpocketing a spectators phone so that a moment later I can make it look like the coin transformed into the phone. I love this trick and it always gets awesome reactions. I want to incorporate it into my stage show however I would like to know how ethical it would be. For close up its fine however for the stage show the phone would end up hanging from the ceiling. This is obviously different from taking it for 10 seconds. It would be away from them for about 3 minutes. Is this ethically right or should I look for alternatives for stage.
