Everyone has done it at least once in his or her life - taking a towel or bed sheet to create a makeshift cape to play superhero. There is no denying that superheroes are the stuff of dreams and imagination. We all in one way or another fantasize about being able to cling to walls, defy gravity with flight, turn invisible during embarrassing moments or gain superhuman strength during dire situations.
