i need to build a roller coaster, we can't use tubing to carry the ball so any ideas on what to use for the track? i was thinking no. 6 copper wire? i need to have 2 hills and a loop. how does this sound? 28" drop into a teardrop loop 12" high and back up hill #2 which will be 14" high any ideas good start?

Building a roller coaster without using tubing to carry the ball sounds like a creative challenge! Using No. 6 copper wire for the track is an interesting idea, but it may not provide the necessary structural support for a roller coaster track. Copper wire tends to be too thin and flexible, potentially causing the track to collapse or bend under the weight and force of the ball.

For a roller coaster track, you need to ensure that the material is sturdy, durable, and capable of handling the forces involved. Here are a few alternatives you can consider:

1. PVC pipe: You can use PVC pipes, typically found at hardware stores, to build your roller coaster track. They are lightweight, affordable, and easy to work with. You can create curves and loops by bending the pipe with the help of a heat gun.

2. Wooden dowels: Another option is to use wooden dowels or rods (such as bamboo) to construct your roller coaster track. These materials offer more structural stability compared to copper wire, making it easier to create hills and loops.

3. Plastic rods or tracks: You can also explore the possibility of using plastic rods or tracks specifically designed for building roller coasters. These may be available in hobby or educational stores and often come with connectors to create different track configurations.

To ensure safety and proper functioning of your roller coaster, consider consulting instructional resources, books, or online tutorials that specifically guide you in building homemade roller coasters. These resources will provide you with step-by-step instructions, safety guidelines, and tips on suitable materials to use, allowing you to create a more reliable and enjoyable roller coaster experience.

Remember, safety should always be a top priority when building any kind of amusement ride. Make sure to thoroughly inspect and test your design, and consider seeking advice from professionals or experts in the field if you have any doubts.
