Some vegetables contain iron, selenium, magnesium, and other minerals that conduct electricity. Microwaves have electric and magnetic fields, and minerals within the vegetables act as antennae for the electric fields.
When there’s a difference between the electrical properties between two bits of material—say, the surface of one piece of kale and the surface of another nearby piece—it creates an arc of electricity, which we see as a spark. The electrical charge moves from the material with high electrical potential to a surface with a lower electrical potential. Metal utensils and compact discs spark up for the same reason, although with those materials, the phenomena is much more destructive (since there’s a larger amount of conductive metal).
Let’s get back to the electrified veggies. Are they safe to eat?
Yes, but you shouldn’t cook food this way. If the food in question is dry enough, it can catch on fire. This rarely happens with vegetables; in most cases, the food will simply crisp up, and the microwave might shut off automatically to protect its magnetron tube.
Vegetables are more likely to catch on fire if they’re not smooth—crinkly kale, for instance—and salt might help to cause the reaction, as it changes the electric potential of the materials. As NPR notes, kale, green beans, bell peppers, and carrots have especially high mineral content and are more likely to spark. However, sauces and soups that contain these elements probably won’t—the liquid basically puts out the spark before it has a chance to, uh, spark.
Microwaves rarely burn down from vegetable fires, but while this is a fun effect to explore, be aware that it can eventually damage your oven. Turn off your microwave as soon as you see sparks (and consider sautéeing your spinach next time).
If a battery is placed in a microwave, it can potentially explode due to the release of gases inside the battery when heated. This can cause damage to the microwave and pose a safety risk. It is not safe to put a battery in a microwave.
A microwave dinner or a heated blanket would remain hot even when it's cold outside.
It is generally not recommended to use aluminium in a microwave because it can cause sparks, fires, and damage to the oven. If you must use it, make sure it is approved as microwave-safe and follow the manufacturer's instructions.
The turntable in a wirowave oven is there to rotate the food so that it is heated evenly, if the turntable was not there, food would be heated more on one side than the other.
Microwaving marbles is not recommended as they can crack or shatter due to uneven heating. The high heat of the microwave can also pose a safety risk. It's best to avoid microwaving marbles and find other ways to heat or mold them.
A potato wrapped in paper will cook in a microwave oven, because paper does not block microwaves. A potato wrapped in aluminum foil would not cook in a microwave because aluminum foil does block microwaves.
the lettuce and tomato would be washed
well it depends on how it will melt faster.. in the hot sun rather in the microwave.. well of course in the microwave. bbut in the microwave rather than melting it above the fire... then it would melt faster in the microwave also... so basically. it will melt fastest in the microwave.
I would estimate about 140 average lettuce.
a microwave.
Hamsters do explode when placed on a microwave. They explode because the microwaves will make the hamsters heart go faster until they explode. I also heard it was because of radiation but im not realy sure. Correct me if im wrong.
no it is not safe because aluminum is an insulator which means that when u take it out the heat will melt it and cause a serious injury if touched. it is also not safe because any metal heated in a microwave can cause a fire
