By on June 20th, 2016 in science kits

10:15 – Barbara is off to the gym and running errands. This afternoon and the rest of this week we’ll be filling and labeling bottles and making up science kit subassemblies.

One of the problematic chemicals has always been starch indicator, which is a suspension of “soluble” starch in water. We use a 10% m/v solution of thymol in IPA as a preservative. That generally works pretty well, but we sometimes get mold or fungal growth in some of the bottles. We just threw out a bunch of them the other day that had assumed a dark brownish gray cast. They’d still serve their intended purpose, detecting very small amounts of iodine, but their ugliness offended me. So yesterday we tried something different. I made up a small batch of the starch indicator, enough to fill 60 bottles. After they were filled and capped, we put them in a pot of boiling water and let them boil for ten minutes or so. That’s enough to kill any microorganisms present, although not spores.

The bottles are polyethylene, which softens but does not melt at the temperature of boiling water. I was a bit concerned that boiling would deform the bottles severely, so we ran a test recently with just one bottle in a pan of boiling water. It swelled a bit, but did not melt or deform.

Killing spores would require heating the bottles to 121C (250F) in a pressure cooker or autoclave. Unfortunately, it would also melt the bottles. So if just boiling them doesn’t keep them from growing mold/fungus, we’ll have to use a 19th century technology which is still occasionally used today for special purposes. It’s called Tyndallization, and was widely used for preserving food before pressure cookers became widely available.

    Those are words of hate against the LGBTXYZ community. And, truer words were never written. Vegas has to be on the ISIS fukstiks list. There are so many fag/dyke clubs they call the 215 Loop around Vegas the “Fruitloop.” Stay away, far away.

  8. MrAtoz says:

    Here is a summary of ObolaLynch’s “edited” 911 call in Orlando. What a libturd fukstik. As many commenters pointed out: “This isn’t editing, it’s CENSORSHIP by the Federal Government.”

    As Attorney General Loretta Lynch promised yesterday, the Obama administration released partial transcripts of Omar Mateen’s phone calls during his rampage in Orlando. Lynch said that certain references would be redacted, and here’s how one such transcript looks:

  9. OFD says:

    “Stay away, far away.”

    Is 2,500 miles fah enuff? Then again, we’re upriver (or downriver, as the case may be) from NYC and Boston.) And within 70 miles of Moh-ree-all.

    Awful hot here today, too, even with the breeze; thinking about how lovely Greenland and Labrador must be about now; I cleaned up the kitchen, bagged trash, made a dump run, set up a bunch of tools in the cleaning buckets that had gotten greasy and/or slightly rusty, planted the lilac tree and a rose bush, and I’m done in for the day, kaput. And it’s only 3PM. If I get a second wind I might mow the lawn, since there’s been no sign of the neighborhood kid.

    “…Lynch said that certain references would be redacted…”

    What’s actually surprising here is that she even bothered to tell us that they’re redacting/censoring those transcripts. I would have simply assumed it, and that they always doctor that chit in their favor anyway. Or based on how they wanna spin it.

    Hahahaha! More Fed gunnies now than jarhead gunnies!

    “Heat Index” at 90 here right now, with “air quality” and “ozone” warnings. If it wasn’t for the strong breeze all afternoon, this would be like unto a steam oven. I got used to the high temps in SEA back in the day but I’ve been back here in Nova Anglia since then and 55-65 is my ideal temp range. I suppose it’s good for the tomatoes and zucchini, though. Wife doesn’t even wanna try peppers, but I might give them another shot next year, starting the seeds indoor under grow lights. I also plan to try out carrots, beets and turnips for fall harvesting this season.

    I thought others might appreciate the joke. I started Fortran programming at the tender age of 14 by keypunching fortran card decks for Dr. Sun Fu Yang. He wrote the subroutines on the back of 132 column printout sheets. Even though the paper was ruled every five rows, he just kind of randomly wrote all over the place and would draw lines to where his code should go.

  16. OFD says:

    “They will be spared the axe in the first round.”

    Some of them need to be debriefed for any possible intel they may have (slim hope, I know) and then they can put in a few months of warm-weather road-building and bridge repair projects around the country.

    “I thought others might appreciate the joke.”

    Oh, I did, I did; I’ve seen plenty of DCL, bash, vim and PowerShell scripts that were like unto any of the descriptions rendered by Ponytail. Without even getting into Fortran, COBOL, C##, etc., etc.

    The heat index is 73 F here in my office. Oh, the outside heat index is 97 F (actual of 93 F).

    We hit our first 100 F actual day last Friday (unofficial). The heat index was probably 112 F. The wife and I were out looking at a couple of houses to see if they would meet our desires and needs. But all we got was a good sweat as neither had the two master suites that we want in a one story for the long term.

    This heat should break up here tonight with a t-storm or two and we’ll be back to the 70s again for the rest of the week, so I hope to get a lot more outside chit done. If I had to live in 90s+ heat all summuh every summuh I’d seriously consider moving to an igloo in Helluland.

    Miles_Teg is probably asleep, so allow me to fill in for him: Oh, I’ll just bet you’d like to debrief Cankles.

  20. OFD says:

    She ain’t worth debriefing; her brain is a mess, like the rest of her; it’s quite amazing, really, that she can still walk and talk. Larry’s likewise; and both of them from decades of drugging, all kinds of chit, but their original fave was high-quality coke. She is very likely, as is Larry, to self-destruct in the next few months or years, tops.

    I wanna personally debrief Huma.

    Somebody got to Lynch:
    http://www.foxnews.com/us/2016/06/20/fbi-doj-release-new-full-transcript-orlando-shooters-911-call.html

    She should be impeached and tried for treason anyway, along with Obuttstick and a bunch of other people. Trump can build the wall where they will meet the firing squad.

  22. OFD says:

    “…the wall where they will meet the firing squad.”

    Firing squad too good for them, but quick, so there is that. And Nathan Hale was hanged, as was Major Andre, so I don’t wanna put our contemporary treasonous scum on anywhere near the same level as those brave men. The English used to do a real job on traitors, and that would probably pull in chit-tons of pay-per-view.

    In any case, we all know full well, no matter what the gummint tells us, or what the prog and SJW asswipes try to sell, that this piece of shit was a typical wack murdering musloid terrorist. Whether he had direction or assistance should be investigated, and those results released without redacting them. Meanwhile, let us recall the typical mag capacity of an AR-type rifle; 20-30 rounds, unless he got hold of one of them funky aftermarket 100-round drums or something, and no one’s come out with that intel so far. So, even allowing for the fish-in-a-barrel scenario at that club, for him to kill 50 and wound scores more, and allowing for at least SOME misses, he’d have to swap out his mags at least three or four times. And we know from the eyewitness testimony of Jessie Hughes at the Paris atrocity that most derps seem to simply freeze like deer in the headlights and wait to get blasted.

    Some of us wonder if there was at least one or two other gunmen there, and who knows, really, ’cause the huckleberries took three hours to stage their counter-assault and enter the friggin’ building, while who knows again how many folks bled out inside during that obscene period of time.

    Those two scumbags are doing everything they can to help IS, so they should be executed by IS methods: put in iron cages and lit on fire.

    I like the way you think! But the usual beheading thing while dressed in orange jumpsuits works for me, too; dull and rusty kitchen knives, pay-per-view.

    And here’s some funny chit that went down while the nay-shun lost its mind over the Orlando atrocity (incidentally, there have been at least two other musloid terror attacks here since that one; seeing it on your 6PM evening nooz yet???).

    WRT Orlando:
    As each day goes by I am more convinced that this another FBI/CIA “groomed” terrorist sting that got out of control.

    WRT Lynch:
    It looks like Obuttwad was the one that threw Lynch under the bus, as he will do to anyone in his criminal administration. Those that serve him (and it really goes for all current politicians) are serving “at his pleasure”. You would think that the minions would wise up, but they all have the misguided attitude that “he wouldn’t do that to me”. Yes he would, in half a heartbeat.

  28. OFD says:

    “…another FBI/CIA “groomed” terrorist sting that got out of control.”

    I’m not ruling that out; both of those organizations have trouble making a soup sandwich and generally shit themselves regularly and have for decades.

    “… but they all have the misguided attitude that “he wouldn’t do that to me”. Yes he would, in half a heartbeat.”

    Absolutely. As did Larry Klinton and his lovely wife Bruno back in the day…and currently. It is far more dangerous to be a friend or associate with these people than it is for us bumpkins out here in the cabbage patch. It ain’t just ’cause these assholes are evil criminal scum, though; the English were MASTERS of it back during the various Tudor administrations. But we know they don’t read history, so either Obola learned it from the Klintons, or, more likely, all these State actors are indeed, a band of thieves writ large and total fucking psychopaths.

    Want historical parallels in English? Read up on Henry VIII and his two daughters, just for starters; then take a good hard look at Cecil and Walsyngham, and then Cecil’s hunchback kid. Just a hundred years of English history, and for the truly curious, the Wars of the Roses.

    Avoid cities and crowds; can’t get much simpler than that. They’re not gonna hit Saint Albans Bay or Sparta.

  30. Robert Bruce Thompson says:

    Oh, we have terrorists in Sparta. Bonnie, our 90-year-old neighbor, called a few minutes ago to warn Barbara that terrorist black bears had been spotted in the neighborhood. She was worried about Colin. Bears don’t carry black rifles, but they are smarter than fucking muslims.

  31. OFD says:

    “…but they are smarter than fucking muslims.”

    And they’ll eat pork (and anything at all, actually) and drink fermented honey! Mos def, though, keep an eye on Colin and any proximity to visiting bears. Bears and dawgs are cousins but the bears almost always have the upper paw, so to speak.

    And tell Bonnie she’s just a kid; our last two active nuns up the road at one of the RC parishes are retiring; one is 93 and the other is 91 and they’ve been continuously teaching since they were kids themselves.

  32. SteveF says:

    And bears have less mustache than Muslim women, and fewer fleas.

    (OK, honesty compels me to admit that not all Muslim women have mustaches. Only the Middle Eastern and Northern African women over the age of 20 have mustaches.)

  33. Robert Bruce Thompson says:

    With his prick ears and stalking behavior, Colin appears to other animals to be a wolf. I doubt Colin would bark at or charge a bear. He’d go into crouched stalking posture, which tells the bear he’s facing a wolf. And where there’s one wolf, there’s a pack. I suspect the bear would run for it, especially facing a human. Bears are very smart, basically superdogs.

  34. OFD says:

    “Only the Middle Eastern and Northern African women over the age of 20 have mustaches.)”

    I gotta say, their mustaches, as those of the southern European Med tier of women, are more visible, but I’ve also seen the blonde and red and brunette mustaches on women of northern Euro ethnicity, including the ENGLISH. And who knows how many musloid women are actually drop-dead gorgeous but there’s no way to tell. (or how many supposed musloid women are actually men or trannies, for that matter).

    “Bears are very smart, basically superdogs.”

    Also unpredictable. I wouldn’t care to place money on Mr. Bear taking a hike. Normally black bears top out around 200-250 pounds for the big males, but we’re seeing more reports from north-country NY and up here of bears twice that weight. That’s got me beat, plus my stupid dawg. Out in the woods I pack serious bear heat and make every effort to give them and the moose complete right-of-way at all times. Moose, by the way, won’t fucking move. Even if you’re sitting up in your big-ass Ford F-350 crew cab.

  35. SteveF says:

    but we’re seeing more reports from north-country NY and up here of bears twice that weight

    Are you sure these “bears” aren’t the honey from next door? The weight matches, the smell matches, and between the ever-present phone and the ever-present butt* there’s no way to tell if she has a mustache.

    * Cigarette butt, that is, not the probable rear cleavage easing its way out of the size 46 short-shorts.**

    ** Enjoy the little taste of vomit in the back of your throats!

  36. OFD says:

    The reported large black bear sightings indicate that they’re probably twice the weight of either myself or the two next-door-dollymops. In other words, the dollymops each obviously weigh as much as I do, but minus a good foot in height. Just saw the one today, again with the iPad on one arm, the iPhone in the ear and smoking a ciggie; wife and I have figured out that stepdad and mom are paying for all that stuff, plus her free rent and utilities and plus them mowing the lawn there, too. The other wallyhog actually lives in their house WITH them and always has a butt in her mouth.

    Yes, I’ve had the gross misfortune to see both the front and rear cleavages and it’s one of those things you devoutly wish you could un-see.

    Dunno if they have mustaches…; the picture does, but the rainbow has a beard.

    Re code: Back in my undergraduate days, my C professor actually took away points because my variable names were too long. 🙁 I always thought ‘readloop’ made things easier to understand; silly me. But TurboC was perfectly happy to deal with it. The poor souls who didn’t have their own computers and compilers had to deal with QuickC. And somehow I was the resident Fortran / Cobol / Dbase wonk, helping a lot of my fellow students along the way.

    In grad school, I got extra points for my coding projects because I used MilSpec standards in writing them. about 50% of the source lines were comments, I used good variable names, indentions, etc. Of course, I had been coding professionally for 10 years, the last 4 in a MilSpec environment.

    “I much prefer my summertime temperatures reach at least 95* with 90% humidity.”

    Yikes. I think I’ll just stand in the shower to get that. For about three minutes.

    As for coding: I was at a Chinese restaurant the other day and the damn fortune cookies were in some kind of pictograph code. But luckily for me, I was able to get them translated there immediately by Dr. Wun Hung Lo and Dr. Sum Yung Boi.

    Continuing in hostile jocular fashion, we have some commentators on the fun scene down in Orlando, where ordinary Murkan derps prove to be as stupid as ever. Some days you think…there is no hope at all.

  44. OFD says:

    “The Americans hanged Loyalist “traitors” too, didn’t they?”

    Sometimes. But mainly they harassed them and forced them out of their houses, confiscated their properties and made life so miserable that they left and headed for O Kanada. Some of them actually floated their houses on the ocean and towed them up to New Brunswick and Nova Scotia. I also note that the British were responsible for the deaths of nearly 20,000 American prisoners in their horrific ship hulks in New York harbor, a precursor to modern concentration camps.

    “… a good piece on why the AR-15 is so popular, why it’s essentially unbannable, and why most gun control rhetoric is nonsense.”

    That’s a very good article; it’s probably preaching mostly to the choir but maybe some wavering peeps will wake up and smell the coffee. I’d guess, also, that AR ownership is probably double the 5 million in the NSSF stats, one reason being that more and more folks roll their own, with no serial numbers or registrations. (three methods right off the bat: old-fashioned power drill or drill press w/router; polymer fabrication; and the Ghost Gunner). And here in VT I know a guy a couple of towns over with his own CNC machine who cranks out custom ARs for people, test-fires them and makes a nice little piece of change every month.

    One of my parents friends at their church is 104. My Dad took away her car keys when she turned 100 at the request of the mayor. The mayor did not dare do it since he has known her for 50+ years and she would probably beat him. Their podunk town, Port Lavaca, has the red light cameras on Hwy 35 and she was rolling all her right turns. She had over 100 tickets and refused to pay a single one.
