International Exchange Booth

So, I have a game-plan, volunteers, and I managed to secure the closest thing to free reign over an International Booth that I have to help with in November.  Every year they just skype with our sister city for 2 hours and then the last 4 hours is them standing around with their thumbs up their あsses maybe occasionally running a video that they took of the same skype conference.

This year, my plan is to get 3 more groups to Skype with us from around the globe, and then at the same time bring in foreign volunteers (primarily ALTs and CIRs) to be at the booth and talk to people that come up.  Here is where the holes in my plans come in.  Since it is a Matsuri, most people won't stay there the whole time, so I think that asking the same questions to each group on skype won't pose any problem, but I still want to give it some variety just to give people a reason to want to come back for a second or third time.  I also need to figure out exactly what I am going to have the volunteers do.  I was thinking have them play games and hand candy out, but what games besides rock, paper, scissors, and I feel like I could have them do more than just that.

Any input you have is greatly appreciated!
