The safe passengers are looking down at the river far below In this heart-pounding scene from Spider-Man 2 Spider-Man saves the day stopping the train with his high-strength spiderwebs Viewers may think this is just science fiction Some physics students decided to do some tests to see if this scene could be real The students calculated the force needed to stop the train Next they studied the strength of a web created by a Darwin’s bark spider The students found that the superhero’s silk could indeed have stopped the runaway train Part Fact Part Fiction Whether through reading a comic book or watching a movie people are drawn to superhero stories Often these stories are partly realistic and partly fantasy Many show otherwise normal people doing extraordinary things For example in the Superman comic books when he isn’t wearing his superhero outfit Superman looks like a normal person But 6
