The audience isn’t just watching art being made — they’re watching art being performed. It blurs the line between artist and tool. Who

SCIENCE | HISTORY | FACTS | EXPERIMENT on Instagram: "Industrial chains aren’t just metal links — they’re precision-engineered components designed to carry thousands of tons without failure. This video reveals how extreme strength is forged step by step: 1️⃣ Material Selection: High-grade alloy steel is chosen for its ability to handle massive loads, fatigue, and sudden shocks. Even tiny impurities can weaken the final chain. 2️⃣ Heating & Forging: Steel rods are heated to glowing temperatures a
