Here’s a jaw-dropper: NASA uses aluminum foil in spacesuits. Not for insulation, but for protection against infrared radiation. Astronauts aren’t wrapped in foil to keep warm—they’re wrapped in it to not fry from the sun’s direct heat. So, foil is less a cozy blanket and more a silver condom for the planet.
Another shocker: real tin foil was made from tin, not aluminum, and it tasted weird. Food wrapped in tin foil would get a metallic aftertaste, like licking a battery. That’s why we switched to aluminum—and because tin was too expensive for making hats for conspiracy theorists.
