This reminds me of something that my high school Chemistry teacher told us one day. He told us about how gasses require a certain percentage of oxygen to ignite, so, that if you were to fill up an airtight room with 100% hydrogen, such that no oxygen was present, you could open a door to that room and light a match at the threshold without fear of an explosion. Theoretically the gas in the room would only burn at the door-shaped barrier between the hydrogen and the oxygen on the other side. I remain dubious and I want to see Adam Savage risk his life to bust that myth.

Also, actually related to this video: the guy doing the demonstration,Theodore Gray, has an awesome website if you're into chemistry.

Nah, the possums here are cute enough...huge gray rats with skull makeup on their faces (think KISS rats).

This guy's a bit cuter, but being an Aussie critter, we know he's armed with either deadly poison or six inch claws and wants to eat your face when you're not looking.

Comment hidden because you are ignoring dag. (show it anyway)

I'll take those odds - that's definitely he of the graying temples next to Kissinger.

Enjoyed seeing this video as many years ago I used to work on the P-51 in the Air Force Reserve. this brought back a lot of memories. I recall seeing Twilight Tear 463864 out at the Gathering of the Mustangs in Sept 2007 and was attracted to it as at that time it appeared as it been really used. Most of the others appeared fresh off the production line - pretty, but actually too pretty and that isn't the way it is supposed to look - in my view. The owner at that time was Stephen Gray. Is he still the owner?? In this video the aircraft also appears to have undergone some additional restoration - is that so?? If so, is there any other write-ups on the restoration?? Are there any other videos of Twilight Tear available?? Where is Twilight Tear now based?? Thanks for any additional info.

I think I'd have to see it in actual printed form to judge the readability accurately.

BUT, in terms of readability on a display, like the 40" 1920x1080 LCD I'm watching on ... it is quite poor in my opinion. I have a feeling that it would work much better in ink on paper.

33% ink savings sounds pretty good, assuming that the readability on paper is better than a display. That being said, encouraging printer manufacturers to have a more sane approach to refillable ink/toner reservoirs would have a better/bigger impact.

Here in Thailand, where respect for patents / IP is low, (SE Asia is notorious for fake manufactured goods, pirated "soft" media, and hardware hacks / bypasses) I'd guess that around 90% of inkjet printers sold have a tank system glued onto the side with ink lines running into the cartridges from big CYMK reservoirs. I never buy new cartridges unless the print head gets damaged/worn out -- instead, I just buy cheap LARGE bottles of the different ink colors and refill the reservoirs. (Image link of such a setup HERE)

That kind of mod would be a gray or black-market item in the West, but here the laissez-faire attitude about such things has some positive effects. At least, for a consumer (like me), or someone concerned about the environmental impact of all the waste packaging for ink carts (like the dude in this video).

What you posted does nothing to refute the crapiness of the design. Why the recurrent laryngeal nerve give off branches to the cardiac plexus is very simple: The RL nerve is a branch of the Vagus nerve, which is THE source of parasympathetic innervation to the heart. The fact that some fibers may branch off of the Vagus early with the RL nerve and then rejoin the cardiac plexus further along is hardly uprising. That does NOT explain why the nerve fibers that innervates the larynx have to make an unnecessary loop downwards around the aorta.

If there WAS an intelligent designer, he could have easily made those nerve fibers innervating the the larynx split off the Vagus higher up, where the Vagus nerve PASSES BY RIGHT NEXT TO THE LARYNX.

Trying to refute this video by quoting Gray's Anatomy is either a sad misunderstanding of basic scientific concepts or just willful ignorance. Almost as bad as Kirk Cameron and the banana.

They apparently didn't know that that nerve innervates the heart and other chest organs. From Gray's Anatomy:

"As the RL nerve curves around the subclavian artery or the arch of aorta, it gives several cardiac filaments to the deep part of the cardiac plexus. As it ascends in the neck it gives off branches, more numerous on the left than on the right side, to the mucous membrane and muscular coat of the oesophagus; branches to the mucous membrane and muscular fibers of the trachea and some filaments to the inferior constrictor."

And as the lady is separating the nerve from the chest area, she is actually cutting those nerve innervations. Oh, and one more thing. The long nerve does NOTHING to weaken the neck, or the animal itself, as is seen in the following video.

Legally, it's probably a fairly gray area with differing rules in different jurisdictions. I imagine most laws would say something about a reasonable threat, although I don't know how "Stand your ground" laws would affect that.

Morally, if someone is "in your personal space" on public property, in theory you would ask them to back off and then call the cops. Violence should be a last resort, and if they persisted, I'd probably just walk away.

I've heard reports from several men who had sex before and after and said there was zero difference in sensation.

I circumcised my boys but not at all because of aesthetics, nor to "look like me", and especially not for any kind of religious reason.

We weren't dead-set against leaving them un-cut. In fact, we initially figured we'd just let them be natural.

One reason we decided to go ahead with it is we heard about lots of uncircumcised men have issues that require them to have it done later in life (e.g., phimosis, etc.), but the bigger reason was recent (at that time) studies showed strong evidence that circumcised men are at substantially lower risk for serious life-threatening diseases such as HIV and penile cancer (that results from HPV).

>> Yep, it's fucking barbaric. It is genital mutilation of children, period.

Talk about misinformation from a bunch of barbarians.

It's more barbaric to be completely close-minded, backward-thinking, and ignorant as to why there might possibly exist valid reasons to provide your children an almost 100% chance to avoid a plethora of penis-related problems and life-threatening diseases for their entire life in exchange for what's really a very minor procedure when done soon after birth.

The reasons against it? "It's fucking barbaric." Because... why again? "It just is," I'm sure is the best possible response.

The reasons in favor of it? Don't be so glib. Read the research.

Science Daily from Jan 2010:

Other epidemiological studies have shown that male circumcision is associated with significant reductions in HIV acquisition in men.

The strongest evidence for a cause-and-effect relationship between circumcision and HIV risk reduction came from three randomized-control trials in sub-Saharan Africa, where the circumcision rate is relatively low and the HIV infection rate is relatively high. All three demonstrated a more than 40 percent reduction in HIV acquisition among circumcised men.

The largest of these three studies -- in Rakai, Uganda -- was led by Dr. Ronald H. Gray, an epidemiologist at Johns Hopkins and the scientific paper's senior author. Dr. Gray's group collected penile swabs from all of the circumcision trial study participants, which provided the data for the new TGen-Johns Hopkins study.

The new study found that circumcision -- the removal of the foreskin, or prepuce, from the penis -- eliminates an area of mucous membrane and dramatically changes the penile bacterial ecosystem. Significantly, TGen's analysis of more than 40 types of bacteria, using a 16S rRNA gene-based pyrosequencing approach, suggests that the introduction of more oxygen following circumcision decreases the presence of anaerobic (non-oxygen) bacteria and increases the amount of aerobic (oxygen-required) bacteria.

HPV can also cause cancer of the penis in men. HPV infection is found in about half of all penile cancers. It’s more common in men with HIV and those who have sex with other men.

There is no approved screening test to find early signs of penile cancer. Because almost all penile cancers start under the foreskin of the penis, they may be noticed early in the course of the disease.

...

The 2 main risk factors for genital HPV infection in men are having many sex partners and not being circumcised.

The risk of being infected with HPV is strongly linked to having many sex partners.

Men who are circumcised (have had the foreskin of the penis removed) have a lower chance of getting and staying infected with HPV. Men who have not been circumcised are more likely to be infected with HPV and pass it on to their partners.

I understand exactly what he's doing. I'm pointing out that it's possible to cross lines, even with racial satire, and that those lines are gray and fuzzy and worthy of our thought, attention, and dialog. You seem to think that when it comes to racial satire, there shouldn't be any lines, whatsoever. That there's always some 100% correct answer to this kind of question, and that answer is "Colbert is righteous".
You're right, my example wouldn't air. Let's say it did though, and there was an uproar from a portion of the black community. Would you still be saying those folks essentially have their panties in a bunch and need to lighten up?

Man, you Americans with your black and white thinking. Even in these comments its clear that you guys cant even grasp your own simplification of colors and gray shades...
And neither do I for that matter...

See @dag? The gray sarcasm shadow is not enough! We need a big red banner shouting at us

so, we can just call them temporary very-dark-gray-holes.

As someone who researches the effects of video games on education (primarily on learners of English as another language) I can tell you the empirical research into the topic is not nearly so cut and dried.

There was a lot of hype about the "brain age"-type games when they first came out, some of which this video references, but what we know now is that those types of games only make you "smarter" in the sense that they make you better at solving similar puzzle-types. In other words, the gains you see are really just the effects of practice. The supposed "smartness" does not transfer over to other skill areas. See this link for more info: http://pamkato.com/2013/04/17/do-brain-training-games-work-yes-no-and-maybe/

So basically everything referenced in this video can be explained by "practice" rather than by some special characteristic of the video games themselves (certainly video games make the practice part fun, though). Furthermore, there is pronounced lack of research into whether the benefits such as those reported in this video actually mean anything significant (i.e. whether being able to more concretely differentiate different levels of gray when you are younger actually leads to better vision when you are older compared with non-gamers, whether you retain the ability to read small text as you age better than non-gamers, etc.).

I do believe there are cognitive benefits to ALL kinds of gaming (board games, pen-and-paper RPGs, card games like poker, crossword puzzles, tic-tac-toe, etc.) but based on the empirical evidence so far I'm not convinced there is anything particularly special about video games that leads players to become "smarter" in the sort of general sense that is being suggested here.

That's very interesting that NBC _licensed_ the footage. That's damn smart of the skydivers -- they deserve to get money for this. But it does seem like an ethical gray area for the news agencies. Was there a bidding war? Is that common?
