Can you actually swing from spider silk?

Veritasium

Resumen

This video investigates the real-world science behind spider silk, comparing its physical properties to steel and Kevlar. The host explores why spider silk is so tough, how it is produced by spiders, and the challenges researchers face in trying to replicate it at an industrial scale using transgenic organisms like silkworms. Finally, the host puts the material to a practical test to see if it can withstand the forces experienced during a human swing, similar to Spider-Man.

- This is the largest amount of spider silk that's ever been put together for a test like this. So I'm gonna put it to the ultimate test, and try to be the first person ever to swing from spider silk. I don't know if it's going to hold my weight, so let's see. In three, two, one. (Derek yelling) - In "Spider-Man Two," Peter Parker is on a runaway train full of passengers. And to stop it from derailing, he stands in front of the train, fires webs at the buildings around him, and holds on. The webs stretch, some of them snap, but they do just enough to slow down the train and save everyone on board. It sounds like something straight out of a comic book. But real spider silk, the fiber that makes up a spider's web, well, it truly might be this incredible. It's reportedly stronger than steel. It's pretty strong. That's crazy! And 10 times tougher than Kevlar. To find out if that's really tru…
