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 stamping There are two primary types of foil stamping machines. The first type is manual and the second is pneumatic (air powered), which typically used in a commercial print shop. Manual foil stampers are ideal for low jobs and the pneumatic is ideal for medium to high-volume jobs. Commercial Foil Stamping is usually produced on a Kluge foil stamp press or a Heidelberg Windmill retro fitted for foil stamping. Foils come in a wide selection of colors and finishes, from the most commonly used metallic gold and silver to foils with pearlescent and holographic effects. Foil stamping Foil stamping, (also known
