To the Vampire experts...

how do they part their hair so perfectly? or apply their make-up? lol

 

The faucets and dryers are done via infrared. Has nothing to do with reflection, just detection of an object in motion. If they have hands, which can be washed under water without water passing through the hands, then it can be detected and be dryed out.

To conclude, you can shake hands with a vampire and hope they washed their hands after shaking their wee-wee in the loo.

I'm afraid that answer is a little too simple.

We see everything through reflected photons (a light source emits photons, they impinge on an object, the object reflects photons selectively, then we see reflected photons from the object). If vampires are visible but also don't have a reflection, that either means that 1) the photons that are reflected from the vampire must take on a special property of self-cancellation if they hit another reflective surface (something contrary to everyday physics of light), or 2) vampires absorb all photons, such that no photons are reflected and the only reason we think we see vampires is because of their psychic effect on us, in other words their image is created directly in our minds (since vampires are also known to have mental powers over humans, that is a satisfactory explanation).

Explanation #2 is most consistent with what we know about the physics of light and vampire powers. That explanation also provides us with an understanding of why vampires can't stand sunlight. Since they absorb all photons, that energy has to go somewhere and it must quickly turn into self-destructive heat energy and the vampire vaporizes (a good scientific theory provides explanations for phenomena not encompassed by the original data, so this is very encouraging).

So getting back to the bathroom dispensers and valves - as Schatten correctly explains, they operate by emitting IR radiation and looking for a reflection back to sense the presence of an object or movement of an object in front of them. Since vampires absorb all photons, the emitted IR radiation is not returned to the sensor, and does not operate.

Q.E.D.

 

So in so many words, they are a "black hole" for photons, from radio waves all the way up to gamma rays, they absorb it all. Technically, the sun projects a spectrum of energy we cannot see and passes right through the earth. And if vampires absorb all photons, then technically, they are toast in this universe.

 

i miss the good old days when they just bit into the neck of beautiful women. lol

 

wow Yin

 

Yes, I hate it when I go into those cutting-edge bathrooms, why can't they just keep them like they were in the 1400s? I didn't have any problems back then. Oh and to whoever asked how our hair is parted so perfectly... it parts itself. We can't look in a mirror to do it.
