From Pixels to Physical

You've designed virtually—now it's time to build for real.

The Challenge:

Span: 30cm between two supports
Goal: Hold 100 coins (or equivalent weight)
Materials: ~50 matchsticks + wood glue
Time: 1-2 hours (plus drying time)

What you'll learn:

Theory vs. reality (simulation predicts, reality teaches)
Craftsmanship matters (precision assembly is a skill)
Failure analysis (understand why things break)
Iteration mindset (version 2 is always better)

This is where engineering becomes tangible.

Document Your Physical Build and Analysis

Complete the following task.

Document Your Physical Build and Analysis

This is where theory meets reality. Your documentation of failures and learnings is as valuable as success.

Be honest and specific: What worked? What didn't? What surprised you? What would you do differently?

Document your build: What design did you choose? How many matchsticks did you use? How many coins did it hold? What was the main challenge you encountered during construction?*

Analyze your bridge's failure: Did a joint break, beam buckle, or beam snap? What does this specific failure mode tell you about the forces and design? What would you change in version 2?*

Compare your physical results to simulation predictions. If there was a significant difference, what real-world factors did the simulation not account for? What would you tell someone else planning their build?
