Also, another big riddle is - where could I actually get answers to questions like this? I mean, apart from having physics/anatomy/whatever professor as a friend? Internet might have everything, but sometimes seems to lack very basic knowledge of scientific progress. Wikipedia/howstuffworks/etc well-known sites are brief and other sites are either well hidden or non-existing.
Kind of sad that the flagship of information age can satisfy any crazy request for porn, but not knowledge... 
Well if you live in the UK there is a place you can txt with any question and leave them to search the internet for an answer. There is a huge team of them. (Plus it is likely that some one has already asked your question and they have an answer.) It costs £1 tho, so make sure its a good question.
I have used them a number of times, if i have needed an answer and have been away from an internet connection. or if I can't find the answer online. They usualy txt back within 30 mins. (Max i have waited was about 2 hours)
The company is called AQA (Any Question Answered) and the number to txt is : 63336
Hope this helps anyone...
@Stupot: I live just north of Manchester and pretty much all of the people i know call them Cans
eg: "Hi, would you like a Can of <insert generic drink> ?"
But at the same time we do not refer to the generic drink as anything other than its brand name or 'Can'
eg: "Could you pass us a can out of the fridge"
Hope this helps...
