Why Doesn T Aluminum Foil Get Hot
Aluminum foil is made up of tiny aluminum particles that are arranged in a special way to create a super-thin layer of metal. This layer is so thin that it can't actually absorb much heat, even when it's exposed to the intense radiation of the microwave. It's like trying to get a ghost to show up on a thermal imaging camera - it just isn't going to happen!
But wait, you might be thinking, what about all the times I've wrapped a potato in aluminum foil and baked it in the oven? Doesn't the foil get hot then? Well, yes and no - the foil itself doesn't actually get hot, but the air around it does. It's like when you're at a music festival and everyone around you is dancing and having a great time, but you're just standing there, looking cool and unbothered - that's basically what the aluminum foil is doing.
