Hi all, I was really excited when I read about the beer can regattta in Darwin. I was excited because I am a stage tech for my school's theatre and we happen do be doing a play called "Beer Can Raft." Generally, we would just build a platform and put beer cans around it, but the director wants to see if we can really make a raft that'll float. Now we know that we have to plug the cans so that they don't fill up with water but any other help would be greatly appreciated. Jacinta
