What should you never microwave? What's the science behind it?

While microwaves are convenient for reheating and cooking many types of food, there are certain items you should avoid microwaving due to safety concerns or the potential for damaging the microwave itself. Here are some things you should never microwave:

1. Metals: Metal objects should never be microwaved as they can cause sparks, arcing, or fire hazards. Metals reflect microwaves, which can lead to the generation of high electric currents that can damage the microwave or cause a fire. This includes aluminum foil, metal containers, utensils with metal parts, and even metal-trimmed dishes.

2. Aluminum Foil: Aluminum foil can cause sparks and fire when microwaved. The foil can create an electric current that can damage the microwave or cause a fire. It can also cause uneven heating, leading to potential hot spots that could burn you when you remove the foil.

3. Plastic Containers: Not all plastic containers are microwave-safe. Some plastics can melt, warp, or release harmful chemicals into your food when exposed to high temperatures. Look for microwave-safe labels on plastic containers or use microwave-safe glass or ceramic containers instead.

4. Styrofoam: Styrofoam or polystyrene foam is not safe for microwaving. It can melt or release harmful chemicals when heated. Transfer food to microwave-safe dishes or containers before reheating.

5. Eggs in Their Shell: Microwaving eggs in their shells can be dangerous. The heat builds up inside the shell, and the pressure can cause the egg to explode. It's best to cook eggs without the shell or use specific microwave-safe egg cookers.

6. Grapes: Microwaving grapes can cause a potentially hazardous phenomenon known as "plasma balls" or "microwaving grapes effect." When grapes are cut in half or placed close together in the microwave, they can create plasma arcs and sparks, posing a fire hazard.

7. Hot Peppers: Microwaving hot peppers can release capsaicin, the compound responsible for their spiciness, into the air. This can irritate your eyes, nose, and throat, leading to discomfort or respiratory problems. It's better to use alternative cooking methods for hot peppers.

The science behind why these items should not be microwaved varies. In the case of metals, they reflect microwaves and can cause electrical currents that damage the microwave or cause fires. Plastics, styrofoam, and certain materials can melt or release harmful chemicals when exposed to high temperatures. Eggs in their shells can build up pressure and explode due to the steam trapped inside. Grapes can create plasma arcs due to their shape and composition.

To ensure safe microwave use, always follow the manufacturer's guidelines and use microwave-safe containers and utensils.
