How was the roller coaster made?

- Wooden planks or plywood

- Nails or screws

- 2 cylindrical pipes

- Wheels

- Dowel rods or metal pipes

Steps:

1. Design:

- Start by sketching a basic design of your roller coaster. Consider the size, shape, and layout.

2. Frame:

- Construct the main frame of the coaster using wooden planks or plywood.

3. Track:

- Cut wooden planks or plywood into strips for the track. These should be wide enough to fit the model train cars.

- Attach the track to the frame securely.

4. Supports:

- Install vertical support beams or columns at critical points to ensure the coaster's stability.

5. Inclines and Curves:

- To create inclines and curves, gradually raise the track at desired intervals.

- Use dowel rods or metal pipes as support structures for these sections.

6. Rails:

- Attach cylindrical pipes to the sides of the track to serve as rails. This guides the train cars.

7. Wheels:

- Attach wheels to the model train cars. Make sure the wheels can move freely on the rails.

8. Launch Mechanism:

- Design a launch mechanism to propel the train cars onto the track. This can be a simple spring or a manual lever.

9. Braking System:

- At the end of the coaster, create a braking system to stop the train cars safely. This can be achieved using foam blocks, rubber bands, or a simple friction mechanism.

10. Testing and Adjustments:

- Test the coaster with model train cars to identify any issues with the track or supports. Make adjustments as needed.

11. Decoration:

- Add decorations to the coaster to enhance its appearance. You can use paints, stickers, or other materials.
