Building the roller coaster for science was a lot easier than I thought it would be. I hit a couple of bumps in the road when my coaster would not make it all the way through. I figured out that the kinks in the tubing were slowing the ball bearing down, making it difficult for it to get all the way through it. I did not even think to use a blow-drier so I just held the tube until the kink was gone. The kink and the failed attempt were the only problems I faced in the construction of my roller coaster.
