The glass doesn’t wait for the bullet — it reacts instantly. 💥 In high-speed footage, you’ll see glass shatter before the bullet fully passes through. It looks impossible, but it’s pure physics. When the bullet hits, stress waves race through the brittle structure at incredible speeds — often faster than the bullet itself. What you’re really witnessing isn’t matter moving faster, but information traveling through the material, triggering failure in advance. ⚡ This phenomenon is why understanding stress wave propagation is crucial in material science, impact engineering, and safety design — because structures can fail in milliseconds, long before we can even see it happen. #science
