This roller coaster project was a lot easier and more fun than I expected. While building my coaster the first problem I had was the tubing already had a lot of kinks in it when I got it. To fix that I stretched the tubing out across the floor and taped both ends, this got most of the kinks out. In my first design, I had a loop in it. Once I started to work on it I realized that the ball might not have enough force to make it through with a loop. Instead of the flip I did cork screws down the hill and that worked well. The ball bearings worked well, and I tested it a lot of times to make sure I ran smoothly. It actually suprised me how quick the ball went through. Over all I thought this project was pretty easy and fun.
