How do microwaves work? Many people who rely on this household staple to whip up quick meals wonder. While we might take this kitchen wonder for granted, the science behind how microwaves heat food is quite remarkable. If you’ve ever been curious about the mechanics involved in microwave cooking, you’re not alone.
How does it work?
In our latest blog post, we delve into the intricacies of microwave technology with insights from Aaron Slepkov‘s engaging YouTube video, “Why can’t you put metal in a microwave?” available on the TED-Ed channel. The journey begins with Percy Spencer, an innovative engineer who stumbled upon the heating properties of microwaves during World War II. This accidental discovery led to the development of the first microwave oven, turning a melting candy bar into a revolutionary kitchen appliance.
It’s all about water molecules
Microwaves use electromagnetic waves to agitate water molecules in food, creating the heat that cooks your meal. This process involves low-frequency waves interacting with the molecules, generating friction and, subsequently, heat. This scientific marvel simplifies meal preparation and makes it easier to enjoy hot food at the press of a button.

However, while microwave ovens are safe, thanks to their design and use of non-ionizing radiation, the interaction with certain materials, particularly metals, can be hazardous. Slepkov explains the science behind why metals can spark in microwaves. Conductive metals reflect these waves, causing potential sparks that could damage the oven or cause a small fire. It’s a cautionary tale that underscores the importance of using microwaves correctly.
For a deeper understanding and to visualize these concepts, we encourage you to watch Aaron Slepkov’s video below. Whether you’re a science enthusiast or just curious about everyday technology, this video is informative and entertaining. Press play and unravel the mysteries of your microwave oven.
