Design Process:
The coaster underwent multiple stages until reaching its final version. Initially, the coaster featured a drop that was too steep and wire that was too thin, causing the marble to struggle to stay on the track and preventing forming a loop. Subsequently, two different types of wire were experimented with before settling on the final choice of green wire. Additionally, explored various methods of maintaining a consistent distance between the tracks was explored. Initially, thin pieces of metal were soldered to each wire to keep them together, but issues arose with the solder not adhering well after switching wires. Consequently, using popsicle sticks and hot glue were transitioned into use to ensure the track retained its shape.

A Few Calculations
Throughout the course of building the Swift Coaster, a number of difficulties were encountered during the design and build process. The initial starting height proved too steep, resulting in the marble being unable to stay on the track. Once this issue was addressed, it became evident that the initial metal wire used was too thin and incapable of retaining its shape. Moreover, the sharp ends of the wire created a hazardous work environment. Consequently, it was determined that different wire would need to be utilized, which proved significantly more effective and capable of retaining its shape. Subsequently, a few minor problems arose. Upon creating the loop, it was discovered that the only reliable way to make it function was to maintain it at a certain angle. The group then spent half an hour determining this angle and adding the necessary supports, a process that had to be repeated on the turn. Overall, throughout the process of designing the coaster, their problem-solving skills were tested but ultimately not surpassed.
The initial screws used were too long and resulted in cracked wood.
