Microwaving Milk Tea for 30 Seconds Nearly Set My House on Fire: These 3 Foods Should Never Be Put in a Microwave

A young woman recently shared a harrowing experience: she placed a cup of cold milk tea into the microwave, set it for one minute, and stepped away to rinse her straw. After just 30 seconds, she heard crackling sounds and saw sparks inside the microwave. Alarmed, she immediately stopped the microwave and opened the door, only for flames to burst out. She had to use a kitchen spatula to push the burning cup out, extinguishing the fire.

Photos revealed the top of the cup completely charred and the interior of the microwave blackened with smoke.

Why Did the Milk Tea Catch Fire?

According to Mr. Lý Vũ Giang, Deputy Head of the Propaganda Department of the Fire Prevention Office in Xicheng District, Beijing, the fire was primarily due to the cup's material. Many milk tea cups are made of paper or plastic, and to prevent leakage, some paper cups are lined with a thin layer of metal.

Microwaves heat food by emitting electromagnetic waves that cause water molecules to vibrate, generating heat. However, metals reflect these waves, leading to the formation of electric currents and localized high voltages, which can produce sparks. These sparks can reach temperatures of thousands of degrees Celsius, easily igniting the paper or plastic materials of the cup.

Three Foods That Should Never Be Microwaved

1. Eggs in Shells: Heating whole eggs in the microwave can cause pressure to build up inside, leading to the shell cracking or even exploding.

2. Deep-Fried Foods: The high temperatures can cause the oil to splatter and ignite, posing a fire hazard.

3. Low-Moisture Foods: Items like nuts and dried meats can easily catch fire due to their low water content.

Items to Avoid Placing in the Microwave

• Metal Objects: Items like knives, forks, and aluminum foil can cause sparks, damaging the microwave or starting a fire.

• Sealed Containers: Glass or plastic bottles with lids can build up pressure and explode.

• Regular Plastics: Non-microwave-safe plastics can deform and release toxic substances. Always use microwave-safe plastics.

• Ordinary Glassware: Regular glass may not withstand the heat and can crack or shatter. Use heat-resistant glassware.

Safety Tips for Using a Microwave

• Not all items are microwave-safe. Always check before use.

• Monitor the microwave while it's in operation.

• If you notice smoke, sparks, or unusual noises, immediately unplug the microwave.

• If the situation is uncontrollable, evacuate the area and seek assistance.

A small oversight can lead to significant consequences. Always exercise caution when using a microwave.
