Roller Coaster

So me and my friend are doing this thing for the Science Olympics at our school. We have to build a roller coaster entirely out of paper and tape. We have to get a lot done and I don't thing we will finish. We haven't even assembled it yet and it is due Friday!! I don't know what we are going to do!! We still have to make the rest of the pieces and make designs on it. Then we have to build it!! There is no way we are going to finish but I am still hoping.
