While doing my roller coaster project I did not run into too many problems at home, but the problem I did run into was when I had too many loops. This cause the ball to stop in the middle of the coaster. Another problem i ran into was all those kinks. Because of these kinks I had to cut a lot of my tubing, but luckily I had bought 20ft. so cutting of a few kinks did not affect the length so that it would be too short to even use. My roller coaster worked perfectly at home, but I think the bus ride did greatly affect the outcome because of all the bumps and taking it on and off the bus. Doing this project did teach me a lot of how much trouble real engineers have with making a real roller coaster. Overall, I liked it because it was fun and taught me many things about physics.
