When I get excited about a movie, my only way of calming down is to do a little physics. That explains why I found myself pondering Hooke's law and Young's modulus while watching a trailer for Spider-Man: Homecoming. Oh, wait. Before going further, I should provide a spoiler alert, just in case you're the type who doesn't even watch trailers. I consider trailers fair game. You have been warned. I'm not sure just what's happening in this scene, but it looks exciting.
