The Dark Ride
By: Jessie, Jordan, and Jonathan

2. Introduction
Our project’s goal was to design a roller coaster that transports an object in a specified time.
Materials :
Rubber Tubing ($7)
Tie Wire ($2)
Ball Bearing ($.19)
Cardboard Cylinder ($7)

3. The Engineers
Jonathan Jessie Jordan

4. Overview
The ball bearing is put inside the tube at the top of the cylinder. It travels through 8 circles, a loop, and 4 more circles until reaching the end of the coaster.
The ball goes from gravitational potential energy at the top to kinetic energy throughout the ride.

5. Conclusions Major issues with construction:
Finding proper materials.
Consistency with length of ride.
The coaster took about 5 hours to build. With the reports and presentation the total time spent on the project was about 10 hours.
