Some students have examined the physics behind Batman’s cape (the one from Batman Begins, which goes rigid when a current is passed through it).  They were hoping to discover whether he could actually fly using it.

The conclusion?

He could fly almost twice as far as he does in the film – around 350m if he jumped from a building 150m tall.  Alas, when he landed he would be moving too fast and would become “a little bit splattered”.  He would be better off with larger wings.

Do physics problems like this annoy you when you discover them in novels and films, or do you just happily suspend your disbelief?
