But believe me, reading the manual can make all the difference, especially when it comes to heating liquids for long periods. Ignoring these guidelines can result in serious domestic accidents, ranging from burns to unexpected explosions.
So, thinking about safety and everyday practicality, there is a technique for heating liquids in the microwave without putting your health at risk. Understand.
First of all, the microwave, whose origins date back to the 1940s, is the result of technological advances in the area of microwave communications during the Second World War.
That's because Percy Spencer, an American engineer at Raytheon, accidentally discovered the microwave heating effect when a bar of chocolate in his pocket melted near a piece of radar equipment. This discovery led to the development of the first commercial microwave oven in 1947.
Since then, it has become a must-have in modern kitchens due to its incredible efficiency and convenience. Thus, its main use lies in quickly and uniformly cooking food, heating pre-cooked meals and defrosting.
When heating liquids such as water, the coffee or some broth in the microwave, there is a possibility that they will reach temperatures above the boiling point without showing visible signs, such as the formation of bubbles. This occurs mainly in smooth, uniform containers, such as plastic ones with narrow edges.
The danger arises when you remove the container from the microwave, and simply shaking it can trigger sudden, vigorous boiling, resulting in potential serious burns. To prevent these problems, a simple solution is within your reach: place a spoon in the container.
The spoon acts as a nucleation point for air bubbles, preventing late and dangerous boiling when touching the glass, cup or bowl. However, it is crucial to mention that the choice of spoon material is vital. Avoid metal spoons as this can also result in explosion hazards.
So, the next time you use your microwave to heat liquids, remember this simple but effective tip found in the instruction manuals. After all, your safety and well-being are worth the small effort of following the guidelines provided by the manufacturer.
