Tin foil hat validity, as the effect of strong radio waves has been documented for quite some time. A well-constructed aluminum foil enclosure would approximate a Faraday cage for parts of the body enclosed by metal, reducing the amount of radio frequency electromagnetic radiation passing through to the parts of the body covered by the foil. Unlike a foil hat, a Faraday cage is a complete enclosure. A foil hat does not protect the face, and other uncovered areas of the body are not protected. A common high school physics demonstration involves placing an AM radio on aluminum foil, and then covering the
Foil (fencing) torso, where the vital organs are. In 1896, foil (and saber) were included as events in the first Olympic Games in Athens. Women's foil was first competed at the Olympics in 1924 in Paris, and was the only Olympic fencing event in which women competed until women's epeé was introduced at the 1996 Olympics. Nowadays, women's fencing is just as popular as men's, and consists of all weapons (foil, epee, and sabre). Ratings exist in order to separate different level fencers from each other in order to create an even-playing field. A higher ranking is earned by performing well at
