Red Hot Steel vs Spark Plug Ceramic - Video

This glowing red metal is being destroyed by a spark plug. Yeah, the white ceramic part. The steel is spinning so fast that friction makes it glow red hot, but instead of melting or cracking, the spark plug ceramic keeps grinding deeper into the metal. That tiny piece inside a spark plug is engineered to survive extreme heat, massive pressure, and thousands of explosions every minute inside an engine. So even against red hot steel it still refuses to break. That’s not normal ceramic. That’s engineering on another level.
