Do you know about the 5000 yen aluminum foil hat? The origin of the aluminum foil hat comes from the 1927 science fiction novel "The Tissue-Culture King." In the story, the main scientist uses a tin foil hat to protect himself from mind control.
After the 1920s, concerns about the appearance of 5G towers increased, leading to more hat products claiming to protect against electromagnetic waves. These hats became popular among conspiracy theorists as a way to prevent "government mind control."
However, a study by the Massachusetts Institute of Technology spent 34 million yen and found that aluminum foil hats do not block electromagnetic waves. Instead, they can actually amplify signals at certain frequencies. Creating a complete electromagnetic shield is difficult, even in the latest research facilities, and a hat that only covers the head is not effective. Ironically, this protective gear, born from anxiety, has been shown to have the opposite effect scientifically.
