Zombie Roller Coaster

In order to save mankind in North America everyone must be transported to a safe zone in Hawaii.  Your task, if you choose to accept it (which you will), is to make the fastest roller coaster ever that includes up and down hills and possibly a loop.  You will have to track your progress in a team  journal and present all your information in a powerpoint when you are finished.  You must also present all of your ideas for coasters and a real life scale model of the one you decided to make.

You will only have two weeks to accomplish these goals.  You must work together as a team to save humanity.  Good luck!
