Teams are tasked with building a roller coaster out of wooden canes, pipes and zip ties in order to displace a ball from point A to point B. A minimum length and design brief need to be followed, along which each team builds a section of the track. Later these sections are put together to form a gigantic roller coaster which will act as a circuit to test using the rollers. The ball must use only gravity with no human intervention. Bonus points are awarded for loops, drops and spirals.
