Is it sport?

pretty much every school kid round the country ( and probably the world) is doing a project on the Olympics. I take a year 9 Social Studies class here in NZ and i too decided to do a topic on the Olympics. As you can see from the rings though mine has a slightly different focus!
And yep that is real barbed wire! Hopefully it's still on the wall Monday morning, or else my friend and I will be very upset ( we spend half of sunday putting the display up, and she a lot more time making the rings)
Thanks Max :-)
