The reason that we can’t put metal in the microwave is similar to why its a bad idea to run a microwave with nothing in it. If there is fat or water molocules to absorb and transform the microwave energy to heat energy then there’s no problems. However, if there is no absorbtion then the amount of radiation energy builds up in the microwave until it reaches a point where sparks can occur. This of course is a bad thing.

During my searches for this info I also found Unwise Microwave experiments ๐ most of the things on there are just silly, but one piece of information was not only startling but also something I think that everyone should know (assuming its true).
If you heat water for a few minutes in the microwave, it is capable of actually reaching temeratures above 100 degrees C.
‘How?’ you ask?
Well its a bit difficult to explain but I’ll give it a go (much better explination on that site).
Water can only change to steam at a liquid/gas surface, in normal boiling (with an element or on a hob) the temperature is so extreme near these heat sources that seed-bubbles are created and they rise up through the water. In a microwave however, the water is in effect heating itself (by absorbing the microwave radiation) and so there is no localised hotspot for these seed-bubbles to be created. True there will be some micro-bubbles due to the un-even surfaces of the container that holds the water, but this will not be enough to cool the water (as with normal boiling).
Now, you have your superheated water and you take it out of the microwave, you add your sugar and…. KA-POW (not in a good way) with the introduction of all those micro-bubbles (and generation sites) the water will immediately equalise and rapidly cool by changing to steam. This is a pretty explosive reaction and will send boiling water all over the place, burning anyone nearby.
Not good !
So the advice is be damn careful and if you must re-heat coffee or boil water in the microwave, do it for less than a minute.
the reason ppl dont put metal thingys in the microwave is because they start to spark and fizz and generally have a fit…..same reason why we dont put knives into the toaster….granted, i have done both! BUT it was simply to see what happens…and trust me…not a good idea to do either!
/me gets the rubber gloves and goggles.
Superheated water baby, yeah!
…and to think, the worst i’ve ever put in a microwave is a wasp.
Believe me, they get VERY upset!
For the first ten seconds or so, there’s no reaction, then BANG! Something twigs in their mind thinking "F—ING OUCH! I’M OUTTA HERE" and they attempt to fly out of the (thankfully) closed door. Now let me tell you, when a wasp collides with a microwave door trying to escape with it’s life, the impact sound is louder than you’d think! Soon enough, it weakened, and twitched its last after further cooking.
Now, i know i may seem cruel to have done that to the wasp in the first place, but to be fair, he had it coming! When a wasp gets in my face when i’m trying to cook noodles, it’s war! And it was more than happy to feed from the nice warm sugar water i’d baited for him!
And the slamming of the microwave door acted as an example to other wasps.
No wasp has EVER flown in my "noodle-cooking" face since that day.
P.S. – Wasps don’t explode
my god!! i am loving your friend Pete, Rob….he has ideas like me….inventive but generally impractical…
Nice one Pete ๐ these smalled winged beasts need to know their place!

There is no such thing as society….There are individual men and women, and there are families. And no government can do anything except through people, and people must look to themselves first. by
