You might be scared of spiders. But did you know that spiders are like little engineers? Their webs are quite strong. How strong? Some studies show when you have enough spiderwebs, they could be five times stronger than metal. And think of how small they are. If a spider were our size, its web could stop an airplane.
Some people are trying to make spiderwebs even stronger. Students at the University of Trento are working with spiders' silk. They want to change the spider so it will make stronger silk. This means their webs would be stronger, too. The work could have uses in the real world. Think of clothes made from spiders' silk. They would feel so comfortable and they would be quite strong. Maybe very soon, they will make special clothes for police. Not even bullets can shoot through these clothes. It would make the police as strong as Superman!
