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).
because they are not suppose to be microwave
Cause they have metal in them
Dirt and minerals
No, that would not be a good idea, Aluminum foil will spark in a microwave.
first off where would you find a microwave big enough to hold another microwave and second it would not explod it would probably just spark and melt due to plastic and meat frameing
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.
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.
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.
the lettuce and tomato would be washed
I would like toregister my Emerson microwave. How can I register my Emerson microwave?
a microwave.
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
I would estimate about 140 average lettuce.
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.
Don't put the can in the microwave. Indeed not! As they allegedly used to say, Don't try this at home, folks! The beans won't be, even if green. The metal can and could - indeed would. It absorbs the microwave (ultra-short radio) energy and converts it into electrical eddy currents within the metal. And several hundred W into a small amount of thin sheet-metal of low resistance...
