Did you know a spider’s web is a masterpiece of tension? Each strand is pre-tensioned. If it were slack, the spider would miss its lunch. Spiders are nature’s physicists—they “tune” their webs like guitar strings.
Speaking of guitars: tuning a string is all about changing tension. Tighten it, the pitch goes up. Loosen it, the note goes down. Rock stars are just tension wranglers.
And here’s a weird one: The cables on the Golden Gate Bridge have a tension of 63,000 tons. That’s the weight of 12,000 elephants. If they snapped, you’d hear a sound like the sky tearing. They don’t snap. Good thing.
