My semen doesn't glow under a black light, does that mean that i could be sterile?
I think it has to be dried to glow under ultraviolet light. Now I'm gonna have to try this to see.
How long will semen show up under a blacklight?
well wait how old are you...because if your older your semen glows more, so beware young grasshopper. i have much knowledge. message me if you have any other questions because i am quite experienced in blacklight technology.
Does blacklight really work on blood and semen?
You forgot to spray it with Luminol first! Luminol reacts with the proteins in blood and semen to make it fluoresce under a blacklight.
Phosphorescence: Does dry semen really glow under black light like they show on CSI? If so, how does it work?
Yes. So does dried saliva, urine, blood, and a lot of other biological fluids.It works by a process called Fluorescence, or absorption of light of higher frequencies (shorter wavelengths) which triggers spontaneous emission of light of lower frequencies (longer wavelengths). It's the same process by which a fluorescent lamp works, with the mercury vapor inside emitting UV and the phosphor coating absorbing it and fluorescing.A surprising number of organic molecules have energy states that can exhibit this property. And if you can pick out individual wavelengths, it works well to use fluorescence to identify chemicals (see Fluorescence spectroscopy).To the layman, it works like this: Shine UV light (blacklight) on sample, and if it contains one or more of many different chemicals, it will glow. The color that it glows depends on what chemical are in it.
What substances show up under a black light?
black light is just a small part of the spectrum of visible light, if it is used any material you put under it looks different. normally you see 'color' as the result of reflection and absorption of light on a surface. using black light means, everything is absorbed except whitish or flourescend colors. So on a black shirt you not only see dust, or spots of reflecting substances you also see areas where there is a difference in absorption of light at all, as spots. however most outstanding things to see are whitish or flourescend colours. i think the term photoluminescent just emergesin my head, but i'm not sure wether this IS photoluminescence
What does dried up sperm look like?
Chances are it was semen (which does contain sperm). There's really no need to find out if it was or not, just don't worry about it. You said you found it "once", I'm guessing that wasn't today. All that you need to do if it happens again is wash your hands. Once semen has dried the sperm have died. Washing your hands will get rid of any excess residue that's left on you, but it's not like the sperm are going to hurt you...they're dead now.
What does semen taste like?
If I had read some of the answers here before I let a guy ejaculate in my mouth for the first time, I would never have allowed it.I have only tasted the semen of four different guys in my life. The first guy it was hundreds of times; the second guy was twice; the third guy it was 4 or 5 times, and the most recent guy, it must be close to 100 times.I must be very lucky because with the first three guys, their semen had virtually no tasted at at. With the fourth guy, his semen ALWAYS has a distinctively sweet taste. I’m not sure if it is related or not, but I have also noticed his semen is typical completely white, and usually accompanied by quite a lot of clear/opaque fluid. He also ejaculates about twice as much as the first three guys. The texture of his semen is also nothing like some describe it. If anything, I would describe his as be a similar texture/viscosity to heavy cream. Lastly, his semen has almost know smell at all apart from a very faint odor which I actually like. It is just enough to remind you what you are dealing with lol.I’ve have certainly experimented with his semen, tasting it smelling it and etc. With the first three guys I performed oral on, taking a mouthful was easily acceptable, whereas with this most recent guy, I can honestly say that it is not only acceptable, but actually desirable. I absolutely love it.
Does semen stain on clothes?
Yes because it's full of protein. It's a similar stain as the juice from a steak, egg yolk or even peanut butter makes. It can bleach out colours as well if mixed with detergent.
Can invisible blood stains show up under a black light?
My brothers and I are watching the movie 1408 (not my first time lol) and in the movie, the author goes in the room with a black light and supposedly he sees the blood stains (they appear white) on the bed, walls, carpet etc. Then he sees the people who died their (in flashes) that he read in the book he received which showed them bloody/dead in the images in that spot.
Will semen remain detectable with black light on materials that have been washed?
Yes!
