Build a Bridge That Holds 100 Coins
Triangles are magic, tension is invisible, and compression is crushing. Master these forces and build a bridge that defies expectations.
Forces on Bridges: Compression vs Tension
Learn how invisible forces squeeze and pull at every part of a bridge—and why understanding them is the key to building structures that don't collapse
Why Triangles Don't Collapse
Discover the geometric secret that makes triangles the strongest shape in nature—and why every great structure uses them
Bridge Types and Trade-offs
From Roman arches to Golden Gate suspension cables—learn why different bridges solve different problems and what engineers sacrifice for each design
Load Distribution: Where Will It Break?
See invisible stress as heat maps reveal where your bridge will fail first—and how smart design spreads forces to prevent catastrophic collapse
Virtual Bridge Builder: Test Before You Build
Design, test, and iterate in simulation before touching a single matchstick—just like real engineers prototype before construction
Physical Challenge: Matchsticks and Glue
Take your virtual design into the real world—build with actual matchsticks and discover what simulation can't teach you about craftsmanship
