The roller coaster project was a lot easier then I thought. In the process of working on it i had a little trouble with kinks in the tubing. Although the kinks were one of the major problems I was able to get the ball bearing through the entire roller coaster more then once. I had more problems in the kinks with the largest ball bearing. It stopped a couple of times in the middle of the project but I was able to blow out the ball. This project a lot of work but a lot more fun then I had expected.
