i give you a shirtcut:first, you tell your foreign friends:"Come on, guys, now we play a game.First of all, let's be two teams.And each team would have 4 mumbers.We will use tha palm or the back of hand to decide which team you will in.Guys who show the palm would in a team,and who show the back of the hand would in the other team."Then you will get two teams,if they have equal number, that's good, but if it is not,you need to tell the "bigger" group:"Now your team have ( ) more numbers than his, so let's play the palm and the back of the hand again to select someone to that team."hope you good luck
