I had a severe nose bleed the other night and ran water into the sink until half full. When the bleeding stopped I drained the sink and all the red blood went out. However there was a bunch of green looking mater on the sides of the bowl which I washed down. What was the gunk that was on the side of the bowl?
I cleaned the bowl and then filled in up with clean water and found that what ever it was, it wasn’t in the water.
Would appreciate comment as to the greenish matter.
Without running lab tests, I would need to guess. Plasma most likely. Or, as it was a nose bleed, then snot.
ETA: I have never heard of bleeding into a half-full sink. I usually pack a bad nosebleed until it stops.
I’d agree it was either snot and/or miscellaneous preexisting residue that you had not before noticed (eg soap scum, toothpaste leftbehinds, exfoliated skin, etc) that was then stained by the heme that came out of your red blood cells, which were lysed by virtue of being dropped into hypotonic tap water. In other words, bloodstained gunk. The missmash of different things evidently combined to make it appear greenish. Just a guess.
Or maybe our OP is half-Vulcan.
Don’t be silly, suggesting fictional aliens and the like. This can be explained via things we know exist. Obviously, the OP is actually a horseshoe crab.
I’ve noticed that sometimes when I’m cleaning up meat juices and stuff in the kitchen, some cleaners can make the juices turn a greenish color.
I guess it’s possible that the blood reacted with some residual soap or something and changed color.
I recently learned that blood (blue in the veins, red in atmospheric gas) is green underwater in seawater. I don’t know how or why, but I saw it coming out of my own hand, and it was definitely green. Maybe if you tend to dump saline in your sink for contacts, it could cause a similar reaction?
Total shot in the dark, but I was pretty surprised to see green blood coming out of my body 60 feet underwater.
I has to do with water adsorbing wavelengths of light. The color red disappears at a depth of about 15 to 20 feet. Green at 70 feet.
Gah! Absorbing
But horseshoe crab blood is blue (according to Wikipedia). Most likely Vulcan, or perhaps a Vulcan/Crab-person hybrid.
Interesting. I thought it was due to the salinity and lack of oxygen. Thanks for the correction.
