silversolitaireOkay, so I was watching this CSI: NY episode a couple of days ago. I totally forgot what it was called. As a matter of fact, I even forgot what the damn case was. But one thing struck me as odd. The episode opened up with some guy holding his toothbrush into the stream from the faucet. He's not looking and doesn't notice how the water that's coming out of the faucet is blood red. Scene cuts to a guy in the shower being covered with red. Cut to body floating in the water tank on the roof.
Now that struck me as odd. I doubted that a body would manage to tint the entire amount of water blood red like that. Pink tinge maybe, yeah, but not red like normal blood. So I did some mathing. Or rather, I let Tom do the math LOL. Anyway, judged by the size of the tank in relation to the actors, the water level etc. we estimated the amount of water in the tank to be around 25,000 liters (cutting short on the math here). If we assume the average body has 7 liters of blood (even though it'd be odd to think that the body would bleed out completely, let's just think it did) it would break down to about 1 ml of blood on 3.5 liters of water. Why I broke it down to that much?
So I could do this!
The tools.
Dad taking 1 ml of my blood.
Voilá!
Adding it to the water...
Just because it looks kinda cool...
Mixing...
Results!
As you can see, the water is just barely tinted pink. Maybe the amount of water would actually be less, but so would be the amount of blood most likely. Also, as you can see, the blood curdles in the water pretty quickly, so chances are the suspended matter would sink to the ground and no longer tint the water at all.
So I think I've proven CSI wrong. Okay I know, not a huge surprise there, but it was fun anyhow! XD
Yes I know, I'm insane. Move along.

Date: 2006-11-30 01:13 pm (UTC)I used to be chicken about needles. Well, still kinda am to be honest, but I can just accept it. I've gotten pricked so much in the past two years I can't throw a fit over it every time. I'm just not looking when the needle goes in and all is fine.
And yeah it's kinda cool. I'm used to it LOL. It used to suck when I was a kid because I never got to stay home as much as the other kids... hehehe.
