@ttvtipsfortaps: aug 1945: soviets gift the US ambassador in moscow a carved great seal. hangs in his study. inside: a bug nicknamed the thing. designed by leon theremin (yes, the music instrument guy). no battery. no active electronics. they beamed radio at it from outside — passive resonator. hard to detect. found ~1952. listened about 7 years. later shown at the UN (1960) as public evidence of mutual espionage. educational cold war history. not a how-to. #HistoryTok #ColdWar #SpyTok #WeirdHistory #FunFacts
