While everyone knows about Spider-Man’s ability to stick to walls, shoot webs and lift several times his own weight, what few people realize is that the radioactive spider-bite that gave Peter Parker his powers also gave him the proportional sewing abilities of a spider, too. What? Spiders make webs. Why wouldn’t he suddenly gain preternatural sewing ability? It’s even more impressive in the new movie, when you remember Pete made his costume entirely out of deflated basketballs.You ever tried to sew a basketball first? Well, unless you’ve got any radioactive spiders hanging around you, I wouldn’t even bother.
