It's A Kind Of Magic...

I have a Kindle...something that I scorned when they first began to appear until we simply didn't have room for any more books or space to put extra shelves up...I bought one very grudgingly from PC World...it was on offer.

But it's magic...I choose a book from Amazon...click to buy it and lo and behold, seconds later I can sit down and read it. How does it work...that's what I'd like to know...how do the words all fit...where are they actually kept...I mean, I know there aren't any handy cardboard boxes behind the screen but how are they kept separate...why don't the words, from the ninety books I have so far...why don't they get all jumbled up and in a muddle...how does it work so quickly...?

And how does oxygen get into the cylinders...and who was the clever sort of a person who said one day...I know...we'll squash oxygen into little tanks and then people can swim underwater...if they'd like to. I mean...you can't actually see oxygen sort of floating about...so how do they know they've caught it when no-one can see it...

Then there are rockets and spaceships zooming off to remote areas of space...rushing round and round the world without getting dizzy and taking photographs...how do those men on the ground know that rocket is going to land on Mars when everything keeps moving about all the time...and how do they know some sparkly star is a billion light years away...and how do they know when a star is as dead as a doornail and we are just seeing the light from it...I wonder if they make it all up.

I think it's brilliant that my printer prints stuff straight from my laptop...although having said that, the printer does have a mind of it's own and either spits sheets of paper out in a temper or sits there grumbling under it's breath and muttering before it suddenly leaps into action and gives me a fright...

These are only a couple of 'however does it work' puzzles...there must be so many more.
