Microwaves and metal have a complicated relationship. While it's true that putting forks in the microwave is a big no-no, not all metal is off-limits. Metal reflects microwave waves, which is why microwaves have metal walls. This allows the waves to bounce around inside and heat up your food. But when you have lots of metal pieces or sharp edges, sparks can fly due to something called arcing.Arcing happens when negative electrons in metal try to find positive electrons, causing mini fireworks to show in your microwave. To prevent this, we've designed rounded magnets that keep the electrons in check and prevent arcing.So, remember, not all metal is a microwave hazard. And with our specially designed magnets, you can enjoy your microwave adventures without any sparks stealing the show. Happy microwaving!
