CrazyRussianHacker shows a simple way to make clear ice

oritteropo says...

Water normally has some dissolved air in it, which is expelled and trapped when it's frozen leading to the white spots in the ice. To make clear ice you need to avoid the dissolved air being trapped in the ice.

One way to do this is to boil the water before freezing, which reduces the amount of dissolved gases.

What I think is happening here is that freezing only part of the water, and relatively slowly, lets the dissolved gases remain in the liquid part of the water.

Interesting, but anybody got any 'Why'?

I have some intuition: as the water turns to ice it's clear, but once the ice is formed, any additional cooling causes expansion, which causes internal cracks due to the space constraints from the container or the surrounding ice? Obviously frost on the surface isn't going the uniform, so his second example isn't great.

Cash For Gold Scam- Busted

SFOGuy says...

hmmm. from a googled website...

SO HOW CAN WE TELL IF IT'S REALLY GOLD?
These steps can help you determine if your gold is real, and possibly what the true purity is. There are many suggested ways to test gold, and these are some of the most common:
Step 1:
Rub the piece of jewelry across a piece of unglazed porcelain tile. It should not make a black streak. If it does then it is pyrite.If the streak is golden yellow then it is gold. Unglazed porcelain tile can be found at a hardware store.

Step 2:
Use the Moh's scale to determine the hardness of the metal. Gold has a hardness of about 2.5 to 3 on the Moh's scale. Glass on the other hand has a hardness of 5.5 on the same scale. Try scratching glass with the piece of gold. If it scratches the glass, it is definitely not gold, or is mixed with other metals and the purity is very low.

Step 3:
Hold a magnet near the piece of gold. If the magnet attracts the gold piece, then there are other metals mixed in the gold. This is not pure gold.

Step 4:
Purchase hydrochloric acid or sulfuric acid, rubber gloves, and protective eyewear from a hardware store. Use something like a small piece of glass to drop a very small amount of acid onto the gold. If the gold begins to dissolve, then there is some other type of metal mixed with the gold and it is not pure.

Cop Harassing The Wrong BMX Bikers Gets Shut Down

newtboy says...

That's bad enough, isn't it?
Does he really have to be Trump level awful to be properly called a dickhead? I don't think so.
I'm not saying he's a fascist, or the worst officer out there by far. Not being the worst is no excuse for being terrible, and it's a terrible officer who lies to kids, effectively dissolving any trust the children may have had for officers.
Lazy from law enforcement, especially lazy in their knowledge of the law they enforce, is terrible, and absolutely not worth the over $200000 per year he's paid.

Don't get me wrong, the kid could have been more restrained...but the kid is a kid, and so a childish celebration of his 'victory' is not unexpected or so out of line....it's childish. I expect adults in authority to be above that. I expect adults in authority to ignore childish taunts from children (which, to his credit, he mostly did). Mostly, I expect adults in authority to not be childish themselves, even to children. Apparently that's WAY too much to ask, even for >$200000 per year.

Sen. Elizabeth Warren to Republicans: Do Your Job

kceaton1 says...

Warning, this is long. It's a general reply to bob, but really it's a rant about the reality of this country, origins, issue, and where we are headed... Like they say in Horace and Pete, at this point we just might deserve a president like Trump (especially because we are stupid enough to vote for HIM, and for so many Senators AND Congressmen like him or even far worse)...

Reply to bob at the top...


I hate to tell you, but "SHALL", according to the times in which the founding fathers wrote this IS indeed the utmost highest form of that period meaning that you "HAVE TO" do something.

Go ahead and let your own party change what grammar and vocabulary meant from that period--or simply not have enough brains to know what it really means (though most of us know by now their assistants have let them know what it means, they just refuse to believe reality and instead insert their own collective psychotic delusion).

Typically when it says SHALL (BTW, NOT doing that job should be getting them in HUGE amounts of trouble as well), they should be doing everything they can TO nominate a new judge into the open position in their next open session (not a session one year away, so Trump or Hillary has to do it).

If they want to complain about the nominee they CAN, just while they are under scrutiny to go up for the vote. But, they simply are NOT supposed to do nothing and furthermore say they WON'T do anything...

I'll have to look up what the penalty is for not doing this, but it could be a full "boot" from their job. Simply what has been referred to by Republicans in the past as Impeachment. But, then the Senate has to start that (I'm not sure if anyone else can; hence, this is why I said I'd try to see if there is anything else that can be done)

I believe they can also do it at the state level... BUT ALL of this requires for our government officials to do their fucking jobs! PLUS, the citizens that voted them in to give a shit!
----------


We REALLY, REALLY, do not deserve a country like this...it is BARELY alive and well. We are just a few presidential terms away (plus senators and congressmen) before we grind to a complete halt.

Then we can finally watch everything implode on CNN and FOX while REAL extremists take over and then the real fun starts. True extremists taking control with minimal bloodshed and shouting matches, civil war with outcomes that grant us either the NEO-United States (the U.S.A. V:2.0, which might be good), to the Neo-Confederacy (since that is what it all amounts to on the FAR right's spectrum). OR we simply just dissolve and become something entirely new.

Hey, bob did you know that your party used to be JUST like the Democrats of Lincoln's age. The Republican's were more like the Democrat's of our age. Weird right. THAT conservative party died out with Teddy Roosevelt's Bull Moose party; then all of the citizens decided that they simply liked the name "Republican" more (since they'd always voted for that name, right...it'd be weird to change it). That is where the Republican's became a FAR different party than they had been (though they still had a few more GREAT leaders before their schism drove them all, sadly, into madness ). The "Democrat's", they thought slavery was just peachy at first, and now they vote for gay-rights. NEITHER party remembers it's roots and the citizens of the United States have had their idiotic teachers and parents tell them all sorts of stories about how great either party WAS, but never telling them what they are like NOW. We all need to vote for our president, nowadays, without even LOOKING at their part's affiliation. It doesn't do any of us any good. Because none of them have ANY real lineage or links to the old presidents of these United States--they're full of shit.

Just remember, Republicans and their party were formed basically to try and abolish slavery--now they are more likely to put it back into action; a complete reversal of their direction, progressive and liberal!

Democrats tried to keep things the same as it was and to even expand slavery--now they want to allow marijuana to be legal, allow gays to have rights, and essentially pick up many progressive and liberal causes... They too have utterly reversed the direction they were at and taking during Abraham Lincoln's time. Conservative on many topics and wanting to expand the states' rights and abilities. Now they are the ones that would abolish slavery and even have Lincoln on their ticket if he ran...

Our parties in these United States are abysmal, a joke, a farce, and shouldn't even be used... The Founding Fathers would be dismayed over so many issues it wouldn't be even funny. They would more than likely throw OUT the Constitution and start a new draft, simply due to the amount of changes we've made in the WRONG direction and the fact that they weren't able to see the future far enough ahead to imagine gigantic empires made only of Business (with a mere handful of people, not hundreds, thousands, and many more like it was in their times) and how News would become so powerful it is essentially as powerful as the president of the United States--and if watched by enough people it is even FAR more powerful than him/her (like in Russia; The Internet being the ONE thing the Founding Fathers would pat our country on the back over and it's what can restore balance to the people who watch or only can gain information from these entities; a new type of "University" where anything can be shared; truth and facts obtained at every man's fingertips nearly instantly at any point on this planet; it IS the world's greatest WONDER ever made).

Lastly, they would absolutely abhor our parties and how they are used--internally and externally (how our politicians...how all the issues interconnect together; all politicians that receive outside money, they would likely want to have them all impeached, same with those that USE the media; they would HATE parties--but they know they'll always exist, you just have to get rid of the things that LET parties abuse we the people and also the government, and those things are: money and media...).

Republicans are doing their job.
The President needs to submit a nominee to the senate decide whether or not to allow the nominee to become a Supreme Court Justice.

There no rule saying they HAVE TO appoint an OBAMA pick. They don't have to do jack.

Republicans are not bowing to extremest they are stopping extremest from derailing the country.

why is the media ignoring the sanders campaign?

VoodooV says...

the problem is the primaries. Primaries are just simply a shitty system. End of story. The primaries are run by the RNC and the DNC and they don't give a fuck about your vote. The RNC wants anyone but Trump. Trump will not get the nod unless they make some behind the scenes deal that we never hear about. The DNC wants Hillary and it doesn't matter how popular Bernie is.

The RNC/DNC are private organizations and there is no law whatsoever that they are beholden to us.

As the founders warned...parties are bad. I'm not going to tell you that they're equally bad, because that's stupid...but they are both bad.

Reince Priebus and Debbie Wasserman Schultz are the problem and both organizations need to be dissolved, but the Constitution does protect the right to assemble. The person is supposed to matter..not party..not money. Maybe an amendment could be created banning political parties somehow, but insanely difficult to enforce. A lot of shit would go away if we got rid of money in elections though and made them 100 percent publicly funded. It's so much bullshit that we spend so much money on elections in the Internet age.

Just give each candidate their own website...no fancy ads or graphics..just a fucking open source free wiki site where each candidate can put whatever they want on it so people can visit and judge for themselves. Elections are not fucking reality TV shows. This should be a no-brainer.

Climate Change; Latest science update

newtboy says...

New, just released ocean temperature data has shown a dramatic increase in temperatures in the Northern Pacific, and a dramatic decrease in surface temperatures in the Northern Atlantic. As I understand it, those readings are not consistent with normal 'El Nino' patterns. Could this be the beginning of the end of thermohaline circulation? If that happens we'll be facing unavoidable, unpredictable, worldwide, disastrous climate change in short order.
Without the current created by the thermohaline circulations, the oceans die. Equatorial waters become much hotter...fast...and arctic and Antarctic waters become much colder...fast. Ocean organisms can't live through that kind of change, not in any sizeable way anyway. Without the oceans, the entire food web dissolves and we die.
On top of that, without the currents bringing oxygen to the lower oceans, they become anoxic. The bacteria that live in those deep waters will feed on the dead sea life and create toxic gases (hydrogen sulfide) which have, in the past, completed the extinction events by wiping out nearly all life. Once that starts, it's unstoppable and is the end. Let's hope these readings are just an over active El Nino.

What we do today has little to no effect for 50-100 years. That makes us at least 50 years too late to solve this problem, and we are still exacerbating it rather than solving it to this day.
We're hosed.
If you plan on having children in this climate, you are a child abuser IMO, and are adding to the problem with that one action more than almost any other action normal people perform. Your children will most likely not survive to old age, and absolutely won't experience the same quality of life you have.

The Drinkable Book

So in other words the well documented anti bacterial properties of silver which people don't use because medical doses may turn your skin blue for the rest of your life are now being applied to sewage water filled with dissolved nasty solids which won't be removed by the silver therefore making the water drinkable...

Argument: Exercising the rights that my (and other's) forefathers fought and died to procure for every citizen at the risk of his own freedom and/or safety makes the guy filming a hero, and the cops harassing him for no reason the tools.
It's quite sad you can't seem to understand that because a citizens legal rights might be inconvenient to law enforcement does not dissolve those rights, nor does exercising them make the citizen a tool.
I must guess you are not from the USA, so don't understand our system.

Don't Stay In School

Sniper007 says...

Drop out of school so you can learn more important things faster.

One of the very best days of my life was the day I dropped out of college. I was living a dream for MONTHS after that. It was totally unreal. I felt truly free.

Autodidacticism: Look it up.

But he's not saying people should drop out of school. Rather, his message seems aimed at changing what schools teach to children. On this point, I'd have to disagree. The institution itself should dissolve - or rather, it already effectively has. It was never a sustainable idea. It's all upon the parents, and parents should recognize this and start acting like it. In as much as they do so, their progeny will be rewarded for their parents' diligence.

Bystanders Help Save a Beached Great White Shark

Jinx says...

It may be that they can get more oxygen from the air than we can from water, or at least if you keep the gills wet then some oxygen will dissolve into the water on the gills. I'm guessing if the gills dry out they would probably die pretty quickly. But ye, I'm just guessing.

I'm surprised how long they can survive out of water. Certainly longer than a human can survive without air? What kind of damage does it do to an aquatic brain?

Awesome job all around.

Magician Shin Lim Fools Penn and Teller

kceaton1 says...

There were a lot of different tricks in there. A part of me really wonders if the mat on the table is a "printer/scanner" and that "marker" is extremely important. There may be a time-released chemical that helps all of this go down (meanwhile he may actually have a small printer on his body somewhere). When the smoke appears that is when the "card" is doing it's chemical thing (as you could smother one card with this chemical making it fully black, but then the printer could change the chemical pattern again as it is scanned and therefore reset the card with the other signature...).

The truth is, I have no idea how it was done, but I think what he is wearing (and possibly what is underneath--not to mention the pockets that are very hard to determine their location or size), possible chemical reactions used in a few different ways, a slim printer, and a slim scanner. Plus all of the sleight of hand tricks you did or did not catch...

If true, he used some fairly complicated technological prowess, besides his agility to get this done. But, for ages untold the creations made and used by magicians are just as important sometimes as the act.

This would also be THE perfect trick to give Penn & Teller the slip, as they may have never ran across anything like this (I've run into tech that could easily do lots of this--scanner through things, etc; it just depends on what is in that pen exactly...think of it kind of like invisible ink, but it need not stay that way and it more than likely can be made to "dissolve" as some sort of inert gas).

Everything was done here flawlessly, even the music feed into the act making it harder to catch.

Phew, that is long enough and I may only have 50% or so right on this one.

“Psychedelics are illegal not because a loving government is concerned that you may jump out of a third story window. Psychedelics are illegal because they dissolve opinion structures and culturally laid down models of behaviour and information processing.

US surveillance powers expire as Senate deal fails -BBC News

newtboy says...

Did not the supreme court recently declare this program was unconstitutional anyway? I can't understand how they could possibly extend a program that's unconstitutional. That doesn't make sense.

Of course, they try to not admit that this program has been useless. They have ignored that it's not stopped any of the terrorist acts on our soil or elsewhere, not even contributing in a meaningful way towards stopping any. NOT ONCE. It's astonishing that all but one senator is claiming the opposite, when their own independent investigations proved it repeatedly. It's also astonishing that they have completely ignored the findings of the supreme court that declared it unconstitutional. I guess the whole 'swear to uphold the constitution' part of their oath comes with an unspoken caveat 'unless I don't want to, it's inconvenient, or I get paid not to'.

I'm not normally a fan of Paul, but I think he got this one right. I hope the spin machine (now on overdrive from both parties. Impressive, he actually brought the two parties together!) doesn't convince people that he's the one that's got it wrong (him, along with the supreme court) and all the other senators are really working to try to keep us safe and free, all evidence to the contrary not withstanding.

EDIT: Also, the USA Freedom act, the proposed replacement, still has all the data kept, just kept by the private companies involved. Personally, I don't trust private companies to keep my information private. Not only is there the likelihood they'll be hacked, there's also the likelihood they'll SELL that information eventually, no matter what their 'privacy policy' or 'terms of service' say. Often, when companies are dissolved, that customer information is sold as an asset, even when the company is contractually bound to keep it private and NOT sell it. Once the company is dissolved, there's no one to sue over them not keeping their obligation. This happens all the time now. I certainly don't want my calls, to who and when I made them, all purchases, and my location to be sold to the highest bidder(s), I don't know about you.
