Ever wondered how a rice cooker knows exactly when to stop cooking, regardless of how much rice or water you put in? The secret lies in a clever bit of science and engineering.

Rice cookers are surprisingly simple yet ingenious appliances. They use a small piece of metal that changes its magnetic properties when heated to the boiling point of water. As the cooker heats the water, it stays at that boiling temperature until all the water is absorbed by the rice. Once there’s no water left, the temperature rises, causing the metal to lose its magnetic charge, and the cooker automatically shuts off. This ensures your rice is cooked perfectly, without burning.

It’s fascinating to think that something as basic as water’s boiling point, combined with a little bit of magnetism, makes the rice cooker one of the most reliable kitchen gadgets. Whether you're cooking for one or for a whole family, the rice cooker is your trusty sidekick, delivering perfect rice every time, without you having to worry about overcooking or undercooking.

​​So, next time you hit that start button, just remember—there’s a little bit of science magic happening under that lid!
