OK Harry Potter fans: does the phrase “I solemnly swear I’m up to no good” ring any bells. If so, then you’re already pretty familiar with the invisibility cloak, and I’m sure you’ll be happy to know of the real-life-existence of the cloak. With the utilization of carbon nanotubes (rather than magic), university researchers have found a way to make objects seem to “magically” vanish by using similar principles on the existence of mirages.
Scientists at the University of Texas at Dallas have used some carbon nanotubes and generous heating to figured out how to make objects disappear underwater. The carbon nanotubes used are only a single-molecule-thick sheets that are looped into tubes to form a sheet that has the density of air, but with a steel-like strength. Similar to how the optical illusions of mirages occur, the invisibility illusion takes place when heat changes the air’s temperature and density, forcing light to “bend,” making us see a variety of different things. And to think, there’s no need to memorize those pesky spells!
Remember, this only works underwater (for now, anyway). Maybe one day in the future we’ll be able to get our Harry Potter-on, but until then, at least this will make underwater black op missions or playing tag with a group of sharks extremely easier.
