can water explode if kept in the microwave to much?

Yes. It will superheat and have a violent reaction when something touches it.

i think what celine is trying to explain about super saturation is the phenomenon where if you heat a salt solution so that more salt can be dissolved in water, and then cool it to where the saturation point is less than what it was when you dissolved the salt, it won't crystalize. then its a super-saturated solution. the saturation point was changed, and then brought back again, but nothing precipitated out of solution. to bring the solution back to just being saturated you have to shake the container, or there must be a scratch on the inner surface so a crystal can form. this is really cool to watch because suddenly you get tons of crystals forming all over the place. although you need to use a container that has a flawless inside surface without corners. remember, crystals need a place to form. \n\nthe same concept is for superheating water. if you heat (distilled so there are NO impurities) water quickly enough, it will not boil, and you can heat it past its boiling point. only when you create a surface for water bubbles to form will the water boil. but then its explosive boiling and is very dangerous. still very cool to watch though. this somtimes happens in micrwaves, which is why you have to be very careful about heating bottled (or any pure) water in a microwave.

The website TruthorFiction decided this is not true.\n\n"Don't Use Plastic for Heating Foods in a Microwave Oven Because of Exposure to Dioxins-Unproven! & Fiction!"\n\nThis site does an exhaustive investigation regarding "rumors" put out there.  You can read how they came to this conclusion at the following site:\n\nhttp://www.truthorfiction.com/rumors/d/dioxins.htm

adding water to potassium already causes it to explode.  you are correct - the reaction releases hydrogen and forms an oxide of potassium, and the considerably exothermic nature of the reaction generates enough heat to ignite the hydrogen gas.  so, mixing water and potassium solid typically causes a big-time explosion - just like mixing water and sodium.\n\nas for the powdered magnesium in there - i suspect that the explosion would scatter it, and it might ignite - the ignition temperature for magnesium metal is 450 C - so you'd probably end up with white-hot burning magnesium shrapnel flying everywhere!\n\nso, if you're ever thinking about making a nasty bomb, sounds like a good way to do it.

I have heard that, but I doubt it if its only a few times. Just don't put it in the dishwasher, the heat releases chemicals.

heating distilled water for about 10 minutes and then dropping a skittles or something about that size in it...it is \n!!!VERY DANGEROUS!!!DONT TAKE IT OUT OF THE MICROWAVE UNTIL ITS COOLED OFF!!!

ok here is what My Mom does... \n1Take a microwave safe water dish fill it with water,\n2add some baking soda\n3place container in microwave \n4set microwave on HIGH for 5 minutes\n5when finished, dip clean rag in water/baking soda solution and wipe microwave out\n6Most Important. DO NOT USE Household CLEANERS, as they would contaminate the food you are trying to cook. Baking Soda works as a deoderizer and as an abrasive, which help get any and all crud caked onto the sides and roof of your microwave

Of course it will, the microwaves dont just excite water molecules.\nMoirae you are wrong.  How does something burn if it didn't heat up?\nWhy dont you both try rolling up a whole roll of aluminum foil into a ball and putting it in the microwave on high for an hour.

Possibly.  Old microwaves may have leaky or damaged RF seals, or the door is no longer trued to the chassis.\n\nBut, the oven could also be dumping a lot of AC noise into the power lines.

Yes, you can boil water in the microwave.  If you boil water in the microwave you won't see it bubble. So, it may be at boiling temperature but will not produce the bubbles associated with boiling on a stove.  This can actually cause the water to become superheated (above 212 F) because it is not bubbling.  If superheated water is removed from a microwave, it can spontaneously begin to boil out of the container, which can result in severe burns to the hands and face. The addition of a wooden stick (or similar object) helps to keep enough bubbles forming to prevent the water from becoming superheated.\n\nPart of the Contents courtesy of eHow, http://www.ehow.com/how_2297_boil-water-microwave.html

Hmm, I'm sitting here thinking about how microwaves work (yes, I do know how). If the pills have moisture in them (which I'm sure they do), then the electons in the pills can get energized by the microwaves and change the substance of the pills completely. The heat from the outside of the microwave itself though can alter the chemicals in the pills. It might be unlikely that anything happened to yours, but I'd just be on the safe side about it.

It gets cooked. If it's still in the shell, it will explode.

We could... \n\nIF you took a maser  (a laser but insteat of  light it is microwaves) or some other microwave generator and focused the beam on a bucket of water It would heat up the water, and act as a radiator.  \n\nMany radiators work on the priciple of heating up and cirulating water... IT is just that most use a electric heat source to heat the water.  \n\nBut there are some problems.  \n\nFirst ... What if someone or something were to get in the way of this microwave ray... They could get seriosly burned... as well it might be able to cause cancer.  \n\nSecond... IF mircowaves are shown on to a peice of metal instead of heating up the metal it causes a charge to be formed. If the microwave ray hit any metal It would shock who ever was wearing it, or destroy any electronics. (thus you would have to have a plastic radiator as well)  \n\nLast...\n\nThough it is a good idea, and I think it could work... It will be very expencive.  A mircowave used for heating is less that 20% efficent... A maser is less that 5% efficent.  This method will cossume ALOT of electricity.  \n\nBut it is a good idea... IF electricity was cheaper It might be very fesible.

You can certainly revive an otherwise boring day when it explodes, breaks the glass on the front of the microwave, and spills out through your kitchen.\n\nThey make "warmers" to heat in the microwave that you put the ball in AFTER they're heated.  \n\nThe 3 extra yards you get off the tee aren't quite worth the mess you have to clean up by nuking the ball though.

The average cellphone puts out around 1 to 3 watts of UHF frequencies near the microwave band. Yes, it cooks your brain cells if the antenna is next to your head. It just does it very slowly. Figure it out, if you want. A microwave oven will destroy an egg in a couple of minutes using around 800 watts. Figure your cellphone puts out a quarter of a percent of that power and you might destroy enough cells in your brain the size of an egg in about 24 hours. Most folks have plenty of extra brain cells and don't notice this. Those who use their cellphone a lot will find out in time that this is not a myth.

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.

If you heated a tank of compressed helium, the pressure might be enough to cause the tank to burst. The tank would become a missile (Newton's 3 law) and slam into whatever was opposite the breach.
