You may have seen some of the innovations in the world of optical cloaking that have allowed scientists to create a “cloak of invisibilty” by altering the speed of a beam of light. With this in mind, a University of Rochester physics professor and his son decided to show how household items can create their own types of highly-effective cloaking devices.

The result is a highly-entertaining short video showing how allowing water to bend light in its normal fashion can make a great cloaking device.

The paper they wrote together points out that, by rethinking simple optics, real-world cloaking technology could be applied to things like satellites and other things that only require unidirectional cloaking.
