no problem brother.


and one more thing.....just a little advice to everyone here......don't stand so close to the microwave when its on.....it might not harm your food but i think it can harm you
 
lol my mum all of a sudden got so worried about something that happened to a friend of her's. she was saying she wants to get rid of the microwave. :rollseyes: People have been using microwaves all their lives I don't see them with cancer :confused:...

But I guess that's true about not standing close to the microwave.

yeah as long as you don't put metal or a sponge in there or stand too close, i don't think there are any potential dangers of using a microwave.....my mother says the same from time to time about the microwave.....i guess its because of the widespread rumor that eating microwaved food will give you cancer......and that hasn't yet been proven.

yee i heard some dudes liver got cooked or something because he cooked something with microwave open when microwave first came out, i heard dis in chemistry class!

I believe when Amana first came out with the first microwave (Amana Radar Range) nobody was aware that the energy level could be so high that the food would still be cooking for several minutes after coming out. If I recall a few people did get severe internal burns as a result of swallowing food that was still cooking.

If used improperly and if food is not allowed to set for a few minutes after cooking sever burns can happen. Also another phenomena that is potentialy dangerous is water can be heated mush higher then the boiling point and not boil, but if jared or stired it turns to instant steam and sprays super hot water all over.

IV.3. CHEMICAL REACTIONS

The microwave superheating phenomena can be exploited to accelerate homogeneous chemical reactions under atmospheric reflux conditions. To allow for kinetic comparisons with conventional heating, we carried out different common industrial reactions (esterification, oxidation...) with careful temperature monitoring by means of infrared thermometry. Temperature probe immersion in the liquid was found to seriously alter the microwave superheating behaviour. Reaction times were reduced from days under classical heating to minutes under microwave heating. The kinetics were analysed as function of the elevated temperature.

This microwave heating mode allows to conduct reactions at atmospheric pressure with the same yields and reaction times compared to those conducted in expensive closed reactors (under high pressure) in classical heating.

My daughter once left something in the microwave overnight and the next morning it was full of ants, I turned on the microwave thinking it would kill the the ant but they didn't seem to care they just went on about their busyness like nothing was happening.

Has absolutly no effect on most insects. In fact it won't heat most stuff that has a low water content. (Except for metal stuff)

A ruff explanation as to how it workd is it makes water molecules vibrate like mad and that vibration is the heat.

I was trying to find some fun stuff to do with a microwave and all the good sites have this as a header.

Disclaimer: Any kind of experimentation with microwave ovens doing something they are not designed to do can cause the quick destruction of the oven and/or the objects being microwaved. Never attempt to disassemble and operate a microwave oven; you may expose yourself to very hazardous levels of microwave energy.

Well here is something to think about.

This was two years ago mind you. And well this girl in my grade 11 class did an experiment.

Basically, what she did was she planted 2 seeds in a pot and left them until they grew to about 4-5 inches. She kept both pots near a window that was well ventilated and recieved the same amount of sunlight.

Over a period of 6 weeks, whenever she had to water the plants, she'd take two bowls of water and use the same amount. For one bowl, she'd heat it up in the microwave and the other, she'd heat it up on the stove. Then she let it cool to room temperature.

When the water finally cooled down, she poured them into the pot.

She followed this routine for 6 weeks and her result was that the plant receiving the water from the microwave died. Whereas the plant receiving the water from the stove survived.

My teacher repeated the same experiment at his own house to confirm if god didnt have a hand in it. :) Well. The results were approixmately the same.

Anyways what my point is that, surely you dont see humans dying because they heat up their food in the microwave. However, if we were to neglect all the disease and other factors that affect the life expectency, surely we would see a decrease even if it is the most minimalistic.

You just gave me an idea for my grand daughters science fair project.
 
Thank you to explain me about radiations :). First i thought at uraniu radiations which are dangerous for the health.

Radiation is a very broad term. Basicaly it is any form of energy that can be transmitted without a media.

Light
Heat (Technicaly not radiation itself, but the result of it)
Radio and TV signals
Radar


Lots of others some harmless some dangerous
 
OKay I have some confession to make:

I put an egg inside the microwave oven and quick heated for a minute. The egg exploded with a loud bang but the oven is fine. It created quite a mess.
