3. The Puppy Express The device is designed from a plastic tube, a BB, duct tape, and a frisbee. The BB goes through the plastic tube down a ramp, into two loops, around a turn, and spirals down to the bottom. Then it ramps out onto the frisbee where it circles around to the center.

4. Stored Energy BB- Gravitational Potential Energy to Kinetic Energy at the Bottom of the tube The BB has both Gravitational PE and KE throughout most of the ride and ends up losing all of the energy on the frisbee as it comes to a complete stop.

5. The Design The construction of the coaster took two days full of work to decide how we wanted to do it while keeping the cost down to a minimum. Duct Tape=$3, Tube=$7, BB=$4, Box=$3, Frisbee=$3 We also wanted to create the design to actually have certain aspects of real roller coasters.

6. Conclusion A few setbacks occurred during the construction including the fact that we did not have any wood or supplies on the final workday before thanksgiving. So we had to result to duct tape and the box itself for the support. All in all, it’s a roller coaster
