Although the science fiction idea of an invisibility cloak is a Harry Potter - style device that makes objects invisible to the eye, physicists have branched out. In addition to hiding objects from light waves under certain conditions, researchers have made cloaking devices that can mask objects' effects on other types of waves, including sound waves and water waves (SN: 5/18/13, p. 8).
