last i checked food coloring typically is the cause of pump failure for most that use the stuff in their setup but i can't find any dye that would make for a good choice to achieve a blood like red color with my system. i've got a Koolance Exos AI and blocks from Innovatek using Water/Water Wetter. any recommendations would be appreciated.
 
Why would food color contribute to pump failure? Unless it contains corrosive agents, I see no reason (besides staining the inner walls of the tubing) why it would harm a WC system.
 
I dont know why but food colorant is known to cause pump failures. It just is.

P.S. Im using red UV dye and your right. It will not give you a blood red colour. It will start to turn purple instead of becoming a bright red.

hmm.... how much do you think I would need to fill a system? I'll have to check out my local Red Cross.
 
I read somewhere that that BMW/Audi antifreeze version G12 achieves a red color and isn't corrosive....I have a Exos as well atm, and was planning to try it....has the added benefit of being UV reactive somewhat as well. Downside: reeaally pricey for what its being used for.
 
How about breaking open a marker or using rit? I'm not sure if any of them are corrosive. I would imagine visiting an art store would be helpful.

check the supermarket, pork blood is not hard to find. the problem with blood tho i think is it clogs up when it gets too hot.

that would make for an evil system though, powered by blood.
 
You just need to add some anticoagulant to the blood in your cooling loop to prevent clog formation, like heparin or EDTA. They will keep the blood flowing without those pesky clumps!
 
The Red coolant that BMW uses is pretty much the same thing as the GM DexCool coolant. (BTW, Catapillar trucks have been using this stuff for 7 or 8 years now) The stuff is more orange in color than Red, but it would be a good place to start. For that blood look, I would suggest using a combination of UV dyes. UV red and Blue at the right ratio would look really cool together I bet.

what about squeezing the saliva out of about 10,000 mosquitos? that'll keep it from clotting. dunno what the thermal characteristics of blood are though
 
wouldnt real blood turn blue after a while because it would lose the oxygen after a while
 
Real blood would not work too well in your loop. The increased heat in the loop would catalyze the cleavage of the porphyrin ring system inherint to the cytochrome class molecules in blood (eg. hemoglobin). The resultant intermediates (biliverdin and bilirubin) are NOT red, they are black/blue and yellow/orange respectively (this is why a bruise is blue, and goes yellow over time, the release of enzymes that cleave the hemoglobin). Normallly this cleavage does not occur in the abscence of hepatic enzymes but the increased temperature of the loop will catalyze this. My point? your blood filled system will not remain red.

As for deoxygenated blood being blue? wtf? where the he** did you hear that stupidity? Blood is red because the porphyrin stabalized central iron ion absorbs in the red part of the EM spectrum. The only different to the iron ion in oxygenated blood is that it is resonance stabalized and can (theoretically) adopt higher ionization states, its spin state is still equivalent. This means that the absorbed colour is NEARLY identical (deoxygenated blood is actually considered a darker red then oxygenated blood, probably because of resonance stabalization). You're veins are blue because you are looking at them through your skin, light is refracted off the blood, through the vein, and through your skin ... the blood inside the veins is not blue lol.

At any rate, that'd be sick if you could pull it off, im not sure I can think of any way this can be done, EVEN if you keep the temp below body temp (cuz at body temp your body is in a highly regulated steady state devoted to keeping blood healthy through many organs, straight blood @ 40C would degrade rather quickly, this is why red cross keeps their blood stores in a cold room).
 
I can see it now...

"Man's computer dies due to heart attack caused by blood clot!"

I'm sure the blood would get stinky after a while.

"Blood is thicker than water." That phrase alone should make you reconsider using real blood.

thought about that, however, the stuff curdles to easily..:D have to admit it's been funny reading everyone theorizing about the notion of using blood from various sources (human or other) and the possible outcomes of doing so. anyhow it looks like if anything that Rit or Sharpe ink will be the way this goes if i can't find anything else that won't stain both the plastic of the tubes and the interior of the blocks while acheiving the color desired.
 
You might be better off using maroon and lighten it a little. It would be nice if you could get it to be the same color as this smiley -> :mad:
