Albert Einstein famously said “Only two things are infinite, the Universe and Human Stupidity. And I’m not so sure about the Universe.” When we come across things like the Shield: Signal Proof Headwear, and we realize that they’ve got over 200 backers as of this writing, we are reminded of how right he was. This particular product is a hat you wear to help protect your brain from all that electromagnetic radiation that surrounds you, from “cell phones, wi-fi, satellites, tv and radio, microwaves, electric devices, lights or heavy doses of cosmic rays during the flight”. It’s made from a “special signal proof fabric (100% silver coated shielding fabric)” that allegedly blocks most of these signals. Never mind that there’s no scientific proof that electromagnetic radiation is dangerous to humans, better be safe than sorry, right? A £16 (around $23) pledge will get you a beanie or a cap.
