Philadelphia Experiment

The Philadelphia Experiment (or known as Project Rainbow) an alleged military experiment (or some say it is a weapon).

it is said that this experiment has been carried out by the United States Navy at the Philadelphia Naval Shipyard in Philadelphia, Pennsylvania some time around October 28, 1943. The U.S. Navy destroyer escort USS Eldridge (DE-173) was claimed to have been rendered invisible (or "cloaked") to enemy devices.

The story is widely believed to be a hoax. The U.S. Navy maintains that no such experiment was ever conducted, that the details of the story contradict well-established facts about the USS Eldridge, and that the alleged claims do not conform to known physical laws.
