Given the above summary, write a detailed text in English for it.
Allow them a moment of disbelief. Make it sound convincing, letting them know that you've been practicing the lost art of telekinesis for a while now. The more they doubt you, the more fun it becomes. Magic tricks are all about confidence and distraction. The more you make it "entertaining," the less they'll scrutinize your hands and the tricks you're actually employing. They'll be too busy having fun to be suspicious if you turn it into more of a show. They will, hopefully, choose the original hand, since it never opened up to deposit the coin in the other hand. If they choose the new hand, demand they explain to you how you could've possibly had the coin change hands if it weren't for your amazing telekinetic powers.
