Hie guys, would love to hear your feedbacks on this particular routine.

1)Performer shows 4 opaque black envolopes.
2)He invites 4 random audience members to the stage
3)Each audience members shuffles the envolopes.
4)Each audience member *freely chooses one.(Volunteer 1,chooses 1 envolope from 4,volunteer 2,chooses 1 envolope from 3 and so forth)
5)When envolopes are opened,all four predictions make a complete sentence that is in line.

I am quite confident in doing the 2nd and 3rd force for audience no.2 and no.3 ,..what I would like to know is , are they any GREAT methods in seemingly giving a free choice of four envolopes for the 1st audience member?

Thank you!
