Is spider silk bulletproof? It is currently on display at the American Museum of Natural History in New York City. The properties of spider silk also create the possibility for bulletproof body armor. A bullet can penetrate up to 29 layers of Kevlar. But research shows spider silk to be comparatively tougher than Kevlar and stronger than steel.

Answer 2: Spiders make their own silk. How many webs can a spider make in a day? They will build their web at night and tear it down during the day and will rebuild a torn web- so at this point about 27 webs. Males wander to find the and seldom make a web. Hope this helps!
