If enough moisture is evaporated from the food then it will eventually combust. I'd say a slice of pizza for 15 minutes should do it.

That's completely untrue! There is a microwave at almost anybody's house in Japan. It's very commonly used to heat food.\nThere are people who are concerned about the electromagnetic wave that a microwave releases while it's in use. I think it's same as a microwave in the states. (my mom tells me to stay away from the microwave while heating food! She's too conscious!!) This electromagnetic wave are in doubt that it could cause some damage in our brain. But it's not proved yet. And most people don't really care. \nSo everyone uses microwave for heating food in Japan! I'm sure of this.

No, there's no evidence that microwaving food alters its composition or has any detrimental effects on living beings when microwaved items are eaten.\n\nMICROWAVES used in microwave ovens oscillate at 2450 million cycles per second (MHz). On the frequency spectrum , that region is located at the lower end of the radar band, slightly above the frequencies used for UHF (ultra-high frequencies) TV channels, and safely within the NON-ionizing region. However, it is important to note: Although microwaves do not carry enough energy to be ionizing, they can be dangerous. \n\n If microwaves can cook a piece of beef, these waves will also have the same effect on human tissue if it is exposed to high enough intensities for a long enough period of time. Certain body organs are particularly sensitive to this thermal effect. "Thermal" means heat. Thus, it is the heat produced by a hot stove that causes the careless cook to utter a sudden unsavory expletive. Likewise, it is the heat generated by the microwaves that creates the hazard in this case. \n\nInasmuch as the significance for humans of repeated exposure to low levels of microwave radiation is still unclear, there is enough evidence to warrant certain commonsense precautions: \n\nStay at least an arm's length away from an operating microwave oven \nDo not operate an oven when it is empty \nDo not operate an oven if the door will not close properly or is in any way damaged \nNever tamper with the safety interlock switches or the fuse \n\nhttp://en.wikipedia.org/wiki/Microwave\nhttp://www.gallawa.com/microtech/mwdanger.html\nhttp://www.encyclopedia.com/html/m/microven.asp

Microwaves are shielded so that the energy doesn't get out. So, if the roach was on the outside it was as safe as you. \n\nThe energy is focused in the center of the microwave and absorbed quickly by anything there. A cockroach inside the microwave would get steamed a bit, but not too hot to survive.\n\nWhen the US government was testing nukes in the desert, they found cockroaches that survived the shockwave.

Checking Ovens For Leakage\n\nThere is little cause for concern about excess microwaves leaking from ovens unless the door hinges, latch, or seals are damaged, or if the oven was made before 1971. In FDA's experience, most ovens tested show little or no detectable microwave leakage. If there is some problem and you believe your oven might be leaking excessive microwaves, contact the oven manufacturer, a microwave oven service organization, your state health department, or the nearest FDA office. Some oven manufacturers will arrange for your oven to be checked. Many states have programs for inspecting ovens or they may be able to refer you to microwave oven servicing organizations that are equipped to test ovens for excessive emission. A limited number of ovens are also tested in homes by FDA as part of its overall program to make sure that ovens meet the safety standard.\n\nA word of caution about the microwave testing devices being sold to consumers: FDA has tested a number of these devices and found them generally inaccurate and unreliable. If used, they should be relied on only for a very approximate reading. The sophisticated testing devices used by public health authorities to measure oven leakage are far more accurate and are periodically tested.\n\nTips on Safe Microwave Oven Operation\n\nFollow the manufacturer's instruction manual for recommended operating procedures and safety precautions for your oven model. \nDon't operate an oven if the door does not close firmly or is bent, warped, or otherwise damaged. \nNever operate an oven if you have reason to believe it will continue to operate with the door open. \nTo add to the margin of safety already built into the oven, don't stand directly against an oven (and don't allow children to do this) for long periods of time while it is operating. \nUsers should not heat water or liquids in the microwave oven for excessive amounts of time.

Health problems usually associated with electromagnetic radiation (such as cancer) are caused by waves of much higher frequency.  In fact, the light from an ordinary 100-watt light bulb or the heats from a campfire (the heat only not including the smoke) have greater potential to cause cancer.  The only health problem that a microwave could cause is burns, but unless you really do break the glass on your microwave, you should be fine, just be careful about burning yourself on hot dishes and plates.

If there is no oxygen present and it is in a vacuum then in fact it will melt at a certain degree. The wood wont burn without oxygen so you wont get ash, you get liquid wood.

yes. ive seen it on google video. and people go to the hospital for things lie that. its becuase of the mehtane produced, which s very flammable. that is why sometimes garbage dumps start on fire.

Maybe a regular piece of paper, as long as you are right there to watch it and if it starts to burn hurry up and take it out.  It depends on the microwave and how old it is.  I have done it with mine and it was ok.  Be careful.

TruthOrFiction.com has not been able to find any research that supports the fear that food can become contaminated with dioxins either from plastic wrap or plastic in microwave ovens.\n\nThis website does exhaustive research to learn the truth. You can read about what and how they they came to that conclusion here:  http://www.truthorfiction.com/rumors/d/dioxins.htm

Yes, a blowtorch WOULD ignite it. I don't know the temperature it burns at, but I've ignited it with a blowtorch before....

No.\nPotash is potassium ash.i.e. what happens when you burn potassium.\nSoda ash is sodium ash - burnt sodium.\n(both are very reactive)\nThey were known long before the metals even existed (freely)\nThey were used to make glass along with lime (CaCo3)\nAround 1800-1810 Sir Humphrey Davy melted all these mineral ashes and ran an electric current through them with a brand new invention-the battery. In the process he discovered many \nnew elements like K and Na.

If you spend your life  being afraid of everything, then you'll have no life at all. I have a microwave, but I don't actually "cook" with it. I just reheat leftovers and pop popcorn, not because I'm afraid of it, I just like  traditional cooking.

Okay maybe I shouldn't be answering this question. For one I've never even heard or read about that. However I do know from first hand experience...that a cell phone will cause a microwave to arc. I was cooking something, and a cell phone was about six inches from the microwave. As soon as I started the microwave it arced. Moved the cell phone, and the microwave worked just fine. Cell phones are a strange thing.

Because microwaves do not directly heat food.  Instead microwaves excited the water molecules in the food.  The excited water molecules transfer heat to the food, causing it to become hotter.\nGiven the chance, microwaves will boil your blood and cook your muscles.

A microwave excites water thermally and unevenly at that.  A modern microwave in good repair poses no risk to you regarding microwave radiation.  The Faraday's cage (a metal net surrounding the microwave) protects you completely from radiation.\n\nIt is true, though, that water can be heated to an unusual gas-liquid stage if only a small amount of water is heated for half-an-hour or more, which is very unstable when released to an open atmosphere.  Hot water can explode when sufficient supercritical water (much above the temperature for evaporating) meets a quick change in water vapor pressure (lots of steam leaves the surface of the supercitical water).\n\nIn conclusion, under normal circumstances there is no risk to your health whatsoever.  If you microwave materials to really, really, really high temperatures, it is reasonable to expect trouble.  If you open the microwave door and notice an incredible amount of steam escaping, close the door most of the way and leave the area completely.\n\nThe mostly closed door with facilitate or slower and thus more stable transition to room conditions.  Always exercise caution with scalding hot materials, but the microwave has a way of heating things past the temperature that you are planning or expecting.  As the heat dissipates, so does the hazard, no different than with any other machine.

Could G-d microwave a burrito so hot that he himself could not eat it?
