Viewing Guide
- Define the practical problem or constraint behind So You Want to Build a Tunnel... before judging the finished build.
- Identify the mechanism, material choice, or geometry that does most of the work.
- Watch for iteration: failed attempts and design changes often explain more than the final reveal.
- Judge the result by testing, repeatability, and tradeoffs rather than appearance alone.
Safety and Limits
- Engineering demonstrations may omit calculations, load limits, guarding, electrical protection, or long-term testing.
- Verify designs against reliable technical guidance before building or operating a similar device.
