Finding the Viscosity of Pitch

ColdChrist writes "The University of Queensland has a page about a 72-year-old experiment on the fluidity of pitch. There's a webcam where you can try to become the first person ever to see a drop of the pitch fall; eight drops have fallen since 1930 and the ninth is now forming. The experiment 'demonstrates the fluidity and high viscosity of pitch, a derivative of tar once used for waterproofing boats. At room temperature pitch feels solid - even brittle - and can easily be shattered with a blow from a hammer', but it does flow, as the pictures demonstrate." I know this is going to bring up glass comparisons, so we'll head those off: glass is not a fluid.

    instead of colonizing Mars or discovering a cure for cancer, let's see how viscous pitch is! Yeah, great idea. Geez.

    If you ever watch the MTV Video awards or any show on MTV for that matter, it really is like watching "Tarzan". However, Tarzan was raised by apes so gradually he started to mimic the apes as far as behavior. These white kids obviously weren't raised by apes but you would swear they were whenever you see them acting (or better yet pretending) as if they were a bunch of nigger's with their ridiculous speech patterns and hand gestures.

    It really is laughable. It is as if the evolution of the human race is going back to apes instead of the other way around. Another thing why do nigger's always thank god in their acceptance speeches. If god is so good why the hell did he make these nigger's so damn ugly and stupid?

    The lie was that forced equality would elevate the black race and not damage the White Race. The obvious truth is it did not elevate the black race but dragged the white race down to nigger level.

    If watching pitch is what it takes to keep you from gettingbored in University, then you must be a fucking tool! I mean, go lick some pussy, drink some beer, have some fun. You must be a fucking depraved fat sex deprived closet fag or some shit to be watching some glass like sap forming droplets over the course of years. And then to notice that the AC fucking slowed down drop fromation. Now I remember some material science, and I don't recall viscosity being that fascinating to anyone. Apparently glass is a liquid too. Why dont you take up watching fucking Coke bottles, and the added benefit is you can stick your dick in the bottle while you're waiting around.

    This isn't the US? How about screw you, you rotten, jealous baby. I gladly shared my University with foreigners and indigenous types. I am happy to see people come for the opportunity. And that's what it is. The US is what you make of it, and a stinking snarky troglodyte like you wouldn't probably get too far here because you are one of those biker weirdoes whose mother didn't get it across to you your supposed to keep your toys in your yard and not ride them in the middle of the road. You people act all adult, bikers, dressed up and serious, and you're riding a frigging toy [in the road built for cars]. I'll bet you are an inferior father, especially since you listed them last in your sig.

    Who made it to the moon, made the 777, the 707 (first commercial jet, some in service to date), made up all the designs for the computer you are typing that filth on, who has the best Universities in the world? Whose universities have the biggest endowments? What country's Universities create more patents than any other - per capita or not? USA.

    My snarky little toad friend, you would not want to live a world without a great nation where those who are entrepreneurs and innovators can pursue their passions with great rigor and unleash on the world both the wonderful and fearful innovations. We are not good. We are not evil. We just are, as are you. We just exist in a more advanced capacity, and your inferior mind does the most natural thing, lashes out defensively and attempts to deprecate that which you cannot have. This being most of the things I enjoy, and you don't, and a more enlightened existence, as I am aware of your sad positioning and posturing, what causes and the cure for it: come over and stay a while, learn something and make an honest living - something your socialist ass isn't used to.

    OMFG, you look like such a babyfucking nerd on your site. The best viscosity test would be to mix that fluid that normally gets on your hand after slapping the salami with a candle in your ass, and mix that in a womans pussy hole, a "vagina." Yes, women have them, where your pee pee is, there is a hole. Your supposed to drip your fluids in there - not eat it, for christ's sake. I personally think its much more fun to actually fuck women, not take nerd digcam pics with them while talking of pitch experiments. Get laid poindexter. And when you get done fucking the baby, do you have the courtesy to put the diapers back on, Tobie?

    Glass does flow, albeit much slower than pitch. I recall an experiment measuring the thickness (at various heights) of old stained glass windows in some churches. The glass at the bottom of the pane was thicker than that at the top, proving that the glass was flowing.

    Metals exhibit a similar feature. The old lead water pipes used to sag between their supports as a result of self-weight and the load of water. I am sure that most people would agree that at RT, lead is a solid. Materials scientists get around the problem by calling the deformation creep, and attrributing it to the movement of dislocations within the crytals of the metal.

    Your feeble attempts at patronizing the above argument are a hackneyed, decrepit and insubstantial attempt at doing so. I suggest that instead of side skirting the issue and playing the placating buffoon you take a more aggressive approach and try to derail this person's argument. Your lack of ability and insight to refute the former rebuttal is a sad testament to the point to which you took the bait and replied.

    Yeah, you must have tried that on a girl you were trying to fuck, then were shocked to see lame geek humor doesn't get you laid.

    Actually, if you are a fag, a likelyhood to which there is a high degree of probablility, it wouldn't work either as a method of attracting mansex.

    You still watch Nickelodeon and masturbate to anime too?
