I have always imagined what it would be like to fix a camera on one water molecule or be that molecule, and take a journey with it.
Lets say you start in the sea, the fish, and life of the sea.
Then on a hot day you are vaporized and rise high up into the clouds.
You then travel over the ocean until you meet the land and over the beach and towns. You will continue and things around you may get exciting as static builds up in your cloud.
You look below and there is flashes of lightening shooting out of your cloud until it bumps up into a mountain range and all of your fellow molecules start dropping until it is your turn.
Free fall from the clouds, the forest quickly approaching you land with a big splat on a leaf at the top of a tree.
You run down to the tip of that leaf hold on for a second and then drip and fall onto another, then another, and another.
You eventually reach the forest floor and collect with more of your friends and run into a steam.
A passing animal comes and laps you up, you slide down the tongue and take a trip to the stomach, then the intestines, then absorbed and distributed all through the body, until you are no longer needed and taken to the kidneys and then to the bladder and peed out next to the same stream.
You make it back into the stream and run through the forest and the hills and eventually reaching a dam. Here you are sucked up, cleaned and purified and added to with some chemicals.
You snake through pipes until you come gushing out of a shower and run down these lips, breasts, drip off nipples, slide down the stomach, down the pelvis and the legs, over the feet and down the drain.
Back into the slip and slide of the pipes until you reach the gutter. This is by far the nastiest place you have been and you have already been inside the stomach of a forest animal.
Eventually you empty out into a lagoon and the the sea once again.
What a ride. Where in this journey would you want to spend more time, maybe in this picture?
