I was scrolling through tiktok and saw a video claiming that if you wrap your phone in aluminum foil, it won't receive any calls or signals. I wasn't sure if it was real or not, but apparently, it actually works.
It happens because aluminum foil blocks the radio waves that allow the phone to communicate with cell towers. It works like a Faraday cage, which is a conductive barrier that prevents electromagnetic signals from entering or leaving. When a phone is fully wrapped in foil, the signal can't reach it, so it won’t receive calls or notifications.
This is the same principle behind why phones sometimes lose signal in elevators or underground spaces radio waves get blocked by surrounding conductive materials.
So, nothing mind blowing, but it made me wonder: where did the idea of the "guy in a tin foil hat" originate? Did it start in movies? A TV show? Or was there actually a real person who became famous for believing he could block mind control waves with aluminum foil?
I always assumed it was based on someone real because the image of the "crazy tin foil hat guy" is everywhere in movies, TV shows, cartoons, memes. Everyone knows this trope. So where did it actually come from? Who was the first person associated with it? Why did they do it? This had to start somewhere.
Not sure if this is the right subreddit, but I think it fits with the kind of mysteries and weirdness discussed here.
