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 not win. After Duncan died in 1960, the screen property of Rin Tin Tin passed to TV producer Herbert B. "Bert" Leonard, who worked on further adaptations such as the 1988–1993 Canadian-made TV show "Katts and Dog" which was called "Rin Tin Tin: K-9 Cop" in the US and "Rintintin Junior" in France. After Leonard died in 2006, Leonard's lawyer James Tierney made the 2007 children's film "Finding Rin Tin Tin", an American–Bulgarian production based on Duncan's discovery of the dog in France. Meanwhile, a Rin Tin Tin memorabilia collection was being amassed by Texas resident Jannettia Propps Brodsgaard, who
