You know, I'm more squicked by this than I normally would be because I heard Ashton Kutcher and Demi Moore were at the same party and reading that just made me realize that Ashton and Demi together never squicked me and still doesn't. (Well, not that much.)

EDIT: Help me out here. The hottest fires are what color?

i think the hottest fires are white or blue. But that's just a guess.

Probably because when you do the math, his kids aren't much younger than his "date". I was rather squicked hearing about it as well.

Lindsay Lohan is two years older than Bruce's oldest daughter.

EEEEEEEEEEEEEEEEEEEEEEEEEEEEEW.

Also, i/r/t fire:

Color tells us about the temperature of a candle flame. The outer core of the candle flame is light blue -- 1670 K (1400 °C). That is the hottest part of the flame. The color inside the flame becomes yellow, orange and finally red. The further you reach to the center of the flame, the lower the temperature will be. The red portion is around 1070 K (800 °C). The reason there is this variation in a candle's flame color is because air convection pulls the warmer gasses upwards.



Candle flames behave differently in outer space (microgravity) than they do on Earth. The primary reason for this difference is that microgravity provides an environment that lacks buoyant convection, which normally plays an important role in maintaining and shaping a flame on Earth. In Earth's gravity, buoyant convection develops when hot, less dense combustion products rise. The flow that results draws cooler surrounding air to the base of the flame, supplying it with the oxidizer (in this case, oxygen) that the flame requires to maintain itself. Combustion products (carbon dioxide, water vapor, and soot) are carried away from the flame by the same convective flow, which is the dominant transport mechanism in the flame.



In microgravity, however, the process is not the same; there is no buoyant convection, and the transport of combustion products and oxygen occurs by the much slower process of molecular diffusion. This diffusion occurs when there is a high concentration of combustion products and a low concentration of oxygen close to the flame and a high concentration of oxygen farther away from the flame. The combustion products migrate away from the flame and the oxygen migrates toward the flame. The diffusive transport rates in microgravity are much lower than the transport rates due to natural convection in Earth's gravity. As a result, the flame will often appear to burn less vigorously than a flame on Earth, and it will assume a spherical shape that diffuses equally in all directions, rather than the more elongated shape that is characteristic of flames in Earth's gravity.

Okay, not white!
I never knew that!

[astaria51.livejournal.com]

EEEeek.
BRUCE. YOU HAVE A 14 YEAR OLD (ithink). NO.

and, white.

[ceejayoz.livejournal.com]

Actually, I think he's got a 17 year old... only a few months younger.

[robyn-ma.livejournal.com]

He has a sixteen-year-old. *flails in horror*

re: fire colors...

more than you ever wanted to know

There's a color graph. Apparently, an infinitely hot fire would be blueish-white.

[rayaluna.livejournal.com]

Heh. I wonder if that's what he was referring to on the Daily Show the other day??

From personal experience(no, don't ask), the hottest fires are an eye-numbing blueish-white, and looking directly at them makes your corneas try to hide behind your cerebellum, which is not a pleasant sensation to say the least.

[silmaril.livejournal.com]

From physics, too. Blue/white/bluish-white. It's a little misleading, too , since the color of the flame depends on what's chemically oxidizing---burning---as well, but...

[callie-chan.livejournal.com]

*nod* For instance, magnesium burning is always bright white--regardless of actual temperature, I think.

And I remember my chemistry teacher burning something once that glowed bright green as it burned, and made a foot-tall pile of ashes on his desk. Damned if I remember what it was, though.

Hee, we accidentally gave our bunser burner a permanent green stripe. It was pretty. (Sodium, maybe?)

[acetal.livejournal.com]

I doubt it. As I recall, sodium burns orange.

Copper, however, burns green.

[budclare.livejournal.com]

Really? For some reason, I thought that sodium was either green or red. But that was a very long time ago, so I'm certainly not reliable.

Don't think it was copper, since I don't think that we were incompetent enough to drop copper in. But anything is possible. (Well, no, because I remember white powder, I think.)

[budclare.livejournal.com]

Ah, copper chloride. Yeah, that was it.

[ladyortyger.livejournal.com]

I heard that on the radio yesterday.

YUCK.

though he is kinda hot.

GAHHHHHHHHH lol, I'm barely 3 years older than Lohan.

Ew. :)

Someone already told you but the blue part is the hottest.

[greatsword.livejournal.com]

The hottest fires are white. I'm trying to remember the name of that chart (Hersprung-Russel?) Not sure. Anyway, there's a curve of emissions by temperature; once things get hot enough, they're perceived as white.

The pure colored fires (blue, green, etc.) the color comes from a preponderance of electron state transfers -the color comes from the type of material that's burning, not from it's temperature.

[pescivendolo.livejournal.com]

Haha. See, I've always kinda liked Lohan because she's not ashamed of being a little trashy. If Bruce Willis didn't have kids it would all be peachy. But since he does, ew ew ew. Ew. She should be dating his son. Not him. Ew.

[theliel.livejournal.com]

1) meh. it's good to be the king.

2) depends on what is burning. in general it goes roygbiv from red coldest to the blue end hottest, however, wood generally burns red, orange and blue, with impurities changing the colour irrigardless of the heat generated by the reactoin

I loved Gawker's headline for that story: "Bruce Willis Officially A Dirty Old Man."

[stevie-jane.livejournal.com]

Age gaps don't bother me, she's legal, he's looking good, it's their business and I'm not about judging. It's all good.

[ladyortyger.livejournal.com]

The hottest fires are the ones with trollprincesses in them, baby.

Mrow!

Hahhaa, that would have been so much funnier HOURS ago. but I am le slow.
