Doing the roller coaster project had difficult parts and easy parts to it. The biggest ball bearing was tough to get through all the tubing. All the other balls were a breeze when I got the track to work right. The tubing did not kink for me so that was a plus. After I finished the project, I had a party at my house and little would blow into the tubing when I wasn't looking, so i had to take the whole coaster apart and attach a piece of a paper towel to wire and get all the water out. It was gross but the ball would not run through the track unless i dried it. I got to use some power tools so that was pretty fun. The rollercoaster was easier than i thought. The downward spiral was a difficulty because i drilled the holes into the wood in the wrong places. That was the most difficult problem I had. I think the project was very stressful along with all our other school work. I think that NSA should have supplied the tubing instead of making the parents go out and buy it. Overall, it was a very creative and fun project. I enjoyed it.
