Iron vs Glass Friction Test 🔥 The Science Behind Extreme Surface Pressure追加:
Think friction is just about smooth versus rough? Think again.
When metal crushes into metal, >> [music] >> microscopic bumps flatten and literally micro weld together under pressure, >> [music] >> creating insane heat and grip. But glass? It's too brittle to bond.
Instead of welding, it just shatters and scores.
