Tin foil hat radio with a metal bucket. The AM radio is completely inside a metal enclosure. This leads to a noticeable reduction in signal strength received by the AM radio. The efficiency of a metal enclosure in blocking electromagnetic radiation depends on the thickness of the foil, as dictated by the "skin depth" of the conductor for a particular wave frequency range of the radiation. For half-millimetre-thick aluminum foil, radiation above about 20 kHz (i.e., including both AM and FM bands) would be partially blocked, although aluminum foil is not sold in this thickness, so numerous layers of foil would be required
Rin Tin Tin of the movies. Rin Tin Tin and Nanette produced at least 48 puppies; Duncan kept two of them, selling the rest or giving them as gifts. Greta Garbo, W.K. Kellogg, and Jean Harlow each owned one of Rin Tin Tin's descendants. On August 10, 1932, Rin Tin Tin died at Duncan's home on Club View Drive in Los Angeles. Duncan wrote about the death in his unpublished memoir: He heard Rin Tin Tin bark in a peculiar fashion so he went to see what was wrong. He found the dog lying on the ground, moments away from death. Newspapers across
