The video explores the unique workings of microwaves, starting with the magnetron's role in generating electromagnetic waves. These waves interact with food molecules, particularly water, to generate heat. Unlike traditional cooking, microwaves heat food unevenly, leading to hot and cold spots. They cannot melt ice directly, requiring defrosting through indirect heating. Microwaves also affect food texture, making it both soggy and dry. Despite these quirks, microwaves excel at dehydrating food, offering a unique cooking method distinct from other appliances.
