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
Tin toy thousand dollars. Tin toy A tin toy, or tin lithograph toy, is a mechanical toy made out of tinplate and colorfully painted by chromolithography to resemble primarily a character or vehicle. Tinplate was used in the manufacture of toys beginning in the mid-19th century. The invention of sheet metal stamping machines in 1815 allowed for the mass production of inexpensive toys. Tin toys were made from thin sheets of steel plated with tin, hence the name tinplate. Tin toys were a cheap and durable substitute for wooden toys.
