英语翻译（变魔术时说的）现在我将告诉你如何变这个魔术,关键的地方就在于,当你两只手同时翻过来的时候,要把硬币从一个手扔到

I will now tell you how to do the trick.the key point is,when you show both of your hands,you have to throw the coin from one hand to the other.It will seem more real when the distance between the two hands is farther and you throw the coin faster.
