Summary
Mark and BK discussed oxygen absorbers for food storage, explaining that while they can be effective for low-moisture items like wheat and rice, they are counterproductive for higher-moisture foods like lentils where they create dangerous anaerobic conditions for botulism. They explained the simple chemistry (iron filings and salt) and recommended making homemade absorbers cheaply rather than buying overpriced retail versions that are often already expended by the time of purchase. The show also covered Harbor Freight sales, including $3 plastic ammo cans, $10 wireless infrared motion detectors, and silica gel desiccant recharging techniques.

He took off his three-cornered hat and speaking low to me, said, We fought a revolution to secure our liberty. We wrote the Constitution as a shield from tyranny. For future generations, this legacy we gave. In this, the land of the free and home of the brave. The freedoms we secured for you, we hoped you'd always keep. But tyrants labored endlessly while your parents were asleep. Your freedom's gone, your courage lost, you're no more than a slave. In this, the land of the free, the brave. You buy permits to travel and permits to own a gun. Permits to start a business or to build a place for one. On land that you believe you own, you pay a yearly rent. Although you have no voice in saying how the money's spent. Your children must attend a school that doesn't educate. And your Christian values can't be taught. According to the state, you read about the current news in a regulated press, and you pay a tax you do not owe to please the IRS. Your money is no longer made of silver nor of gold. You trade your wealth for paper so your life can be controlled. You pay for crimes that make our nation turn from God and shame. You've traded in your name. You've given government control to those who do you harm so they could burn down churches and seize family farms. and keep our country deep in debt. Put men of God in jail. Harash your fellow countrymen while corrupted courts prevail. Your public servants don't uphold the solemn oaths they've sworn. And your daughters visit doctors so their children won't leave. Your leaders send artillery and guns to foreign shores and send your sons to slaughter fighting other people's wars. Can you regain the freedoms for which we fought and died? Or don't you have the courage or the faith to stand with pride? And are there no more values for which you'll fight to save? Or do you wish your children to live in fear and be a slave? O sons of the Republic, arise, take a stand, defend the Constitution, the Supreme Law of the land, preserve our great Republic and each God-given right, and pray to God to torture freedom burning bright. As I awoke he'd vanished in the mist from whence he came. His words were true, not free, but we have ourselves to blame. For even now as tyrants trample each God-given right, we only watch and tremble, too afraid to stand and fight. If he stood by your bedside in a dream while you were asleep and wondered what remains of the freedoms he'd fought to keep, what would be your answer if he called out from the grave, dill the land of the free? number 2018. We have noticed that there is less chemtrailing activity, especially out in the west. Most weather in North America flows from the west to the east, so anything they do over way west of here flows our direction in due course. So that may be an effect. It may also be the impending ice age. It may be Yeah, they're letting up on the chemtrails and therefore nature is kind of bouncing back in with gyrations into the groove that it wanted to be in before they started. spraying all this stuff. There's no telling what's going on. What I do know is that it's weird. We got snow while two-thirds of the leaves are still up in the trees. Not, you know, continuous blizzard all the way through until March, but you know, we got we did get snow, which is very, very weird. In this area, traditionally, it's always a big question whether you get a white Christmas or not, because if you do, it's the first snowfall that gotcha. But we had snow in early November that's just absolutely nutty. Crazy. And this whole month has been bizarre. It's been bizarre in other fronts as well, but certainly the weather is among those. Have you heard any interesting and particularly salacious theories about what the heck is going on right now with the climate? I'm assuming that's a no. Okay. Nope. Go ahead. Right. So we'll just leave that one an open issue and maybe somebody will figure it out at some point. Meanwhile, other things have been going on that are very, very interesting. Remind me to mention the cryptos because they have been going absolutely berserk the last week But there are a few more traditional topics. I'd like to get back to this time around Mark are we out on? broadcast this evening throw we are in five yeah, okay, this is somebody refreshing the drainage ditch or something what's going on there? Oh, they're no working with cable and fiber optic apparently and they that there were lines running perpendicular to his path. Future, are you going to see to it that there are little flags there that say, you know, buried cable here? Are you going to hope that they figure it out and don't do it again? Well, apparently... Changes and things like that. So if we're going out over the air, there is FCC jurisdictions involved. I will caution everybody to keep your language clean to broadcast standards. I don't think that we have any sort of multi-second delay, so Ed's going to have to be on his toes. If somebody breaks that rule, just mute them instantly on the first offense, and for the rest of the hour, no appeal, nothing here. Trigger on this stuff. We have to stay clean. Okay, so you know nothing I like better than getting other people to do work and and have to do it myself and hover over a red button or something along these lines So, you know, there you go. I'm giving Ed work to do. All right Go ahead If you want to talk to a squirrel just tell the squirrel to keep it clean, okay. All right. Okay I have absolutely no idea I've never encountered this stuff, not tried it. I would be suspicious of it personally. You know, they come up with variations on these classic items and very rarely is the variation a useful thing. Once in a while, but very rarely. So something along those lines, I would buy one can and try the darn stuff if I ever encountered it. I have no idea where it might be available and I've never seen it personally. I'm not sure if it's a salad here normally, it's only in Hawaii and the West Coast, but teriyaki flavored, spam. I gotta pull it down, I didn't look at the... Yeah, go ahead. There's a barbecue flavored one, I didn't hear the word. I would treat it exactly the same way. If I saw that, I'd buy one of them and go try it. I'm not sure that it would be to everybody's taste. If you're putting in stores that may be drawn on by multiple persons, you also need to go kind of center of the road. It doesn't hurt to have a little variety here and there, you know, but I would definitely try that sort of thing before I bought, you know, a dozen or a hundred or whatever of anything along those lines. But, you know, and they were distributing it in World War I, so it was somewhere in that window. It was certainly a big deal in World War II and in Korea. That's one of the reasons it's so popular in Asia is because our involvement in Korea, vast amounts of the sort of stuff found their way into civilian hands. That's why you find it in the Asian food stores. Asian food store and spam in a can will be on the shelf in every Asian store you go to as wedding gifts. probably probably an artificial expense then it's one of these nationalistic things we don't want that the round ice product you know poisoning our populations who are gonna tax the the pants off of it it's uh but yeah it's like you want to see Hawaii riot Well that certainly works if you've got the eggs and the can sits there and waits for you. I personally would not be doing that simply because, you know, one can of Spam is way too much for a single omelette and then it commits me into having three or four omelettes in a row until the can is used up. But, you know, I sympathize with the sentiment. I do remember taking that by preference as one of my emergency supplies whenever I was on a scout, you know, trip. You know overnight hikes all that kind of good stuff because there's not much your so-called buddy could do to ruin your can of spam until it's opened and Just frying it and snuffing it down was enough for a teenager you get some calories and some fats in there and you could worry about the the balanced diet later on when you get back home to You know clean sheets and rough and all that kind of wonderful stuff. Hey break break break. Can we let be careful? Yes, it does. We never get to everything as the way it goes. I wanted to this evening, since we have hopefully a new audience, to revisit some of the ancient and traditional topics that we have discussed in the past, but have not discussed very much recently. So one of those topics is oxygen absorbers. If you get into the, I won't say business, I will say practice of putting up food against future hardship or emergency, one of the things you will encounter in the catalogs are, you will encounter lots of miscellaneous things like aluminized mylar bags and stuff, those are great. You will also encounter oxygen absorbers in the, add copy will say well you gotta use these things to get all the oxygen out so that your stored stuff will be good and so on and so forth and there's some truth to that however BK is going to get up here and say something heretical what is that don't buy oxygen absorbers Well, wait a minute. Oh, BK, why would you say a thing like that? Well, be very, very careful and listen to the words like, you know, a lawyer. Don't buy oxygen absorbers. There are a couple of reasons. First off, sometimes you don't want to use the oxygen absorbers. There are circumstances in which they are actually worse. It is worse to use them than to not use them. These are basically situations in which what you're storing has a high moisture content If what you are storing has a low moisture content like wheat and rice and a lot of things like that And oxygen absorber is a great thing It strips the oxygen out of your container. It prevents oxygen-consuming bacteria, mold, yeast, etc. from growing in your food. It does help preserve things. On the other hand, if the moisture level of what you're storing is higher, for example in lentils, the moisture level is something like 13-14% typically. I think that's about 10%. If what you're storing is higher moisture content than things like rice and wheat and so on, then stripping out the oxygen creates an environment that botulism and some other bad things like it creates an anaerobic environment that's moist. And that's when you will get some really nasty fungi, you'll get botulism, you get things that can kill you if you eat that food. So, you know, what is a wonderful technology under some circumstances can mess you up badly under other circumstances. And since we're being grown-ups here, we have to know the difference. If you want to store things with oxygen absorbers, make very, very sure that it's a low moisture material that you're storing. You can also use these things with non-food items like if you want to use those to help store metallic tools, ferrous tools, and you don't want them to rust. Well, the first line of defense is of course to oil them. But you can also throw in an oxygen absorber, and that's perfectly okay. But if you're saving food, look it up, get out on the web, look up the particular food item and see what the percentage of moisture is there. If it's over about 10%, don't use an oxygen absorber, because you might be actually doing things worse than not having one. The other reason to not buy oxygen absorbers is not the oxygen absorbers. It's the buy part of it. Not only are these things ridiculously overpriced, but when you manufacture them, they go to work immediately. I'll discuss the chemistry in just a minute, but They go to work immediately grabbing every molecule of oxygen that they can grab their hands on and in the factory of course they produce these things and they immediately put them into sealed containers so that they don't degrade. However, when you purchase them at retail you're not buying them from a factory, you're buying them from a distributor. So they're opening up those containers, repackaging them in the plastic envelopes or what have you and shipping them to you. The end result of that is that by the time you purchase an oxygen absorber, very, very often the poorer packaging the distributor used and the poorer handling the distributor used is such that it's expended by the time it gets into your hands. So it's not only a waste of money, it also falsely causes you to believe that you have somehow protected yourself. The other thing is that if you look at the ratings on these things, they say, you know, rated for X many liters or whatnot. That sort of exaggerates the hack out of what's going on. Let's explain the chemistry of oxygen absorbers because, you know, there are people out here saying, gee, I'm not a chemist. I don't want to do any fancy stuff. What's going on? I'll just buy the things. Well, the chemistry is actually very, very simple. They consist of two ingredients iron filings and table salt. That's all they are The table salt causes the iron filings to rust much much faster than they would normally And the iron, when it rusts, binds oxygen and you use iron filings so that as much as possible of it reacts. And that's all there is to it. And you would be astonished how effective they are. Well, you can make your own iron filings if you've got a machine tool or a teenager that you can set to work with a hand file for an hour. Or you can simply purchase iron filings, eBay has them. They're not a restricted item. Add some table salt. Proportions do not matter because all you're trying to do is contaminate the iron filings to the point that they rest quickly. But if you do make them yourself, go ahead and package them up in a little cloth bag or a paper envelope or anything that's porous and immediately get those in those sealed packages because they're going to start working immediately. Back on the old forums back 2006 7 8 something like that. Do we go back that far? Yes, we do I've posted some photographs of Soda pop bottles plastic two liter bottles filled with red beans and I dropped a homemade oxygen absorber in there cranked them down and waited a few days and took a picture and sure enough that bottle is all crumpled up and shrunken and collapsed and It looks very unappetizing and unappealing, but the fact of the matter is that that's what happens when you gobble up 20% of the atmosphere in a bottle like that. oxygen is 20% and the whole thing kind of collapses. Now pop bottles eventually, you know, very slowly diffuse oxygen right through the plastic. So, you know, eventually those things are going to relax and let oxygen back in again. But a homemade oxygen absorber is obviously effective when it can collapse a bottle to that effect. And somebody that finds our old forum over on Yahoo! someplace can probably dig up those photographs. But they are quite striking. So it shows that things do actually work. What do I find it? I was not able to dig up my old calculations and I thought of it a little bit too late to recreate them from scratch. But what I will say is that back in the day when I was packaging up a lot of these things, I would use a quarter pound of iron filings and make those into a dozen oxygen absorbers that I deemed suitable for a 2 liter pop bottle. So there's a rule of thumb, there's a starting point. What I figured is that that would consume the oxygen in a 2 liter pop bottle several times over, therefore compensating for some number of months or years for the diffusion effect through the plastic. And, you know, once the absorber is expended, then you're just back to where you were before anyway. So, you know, you're nowhere soft. You bought yourself a few years of extended storage time. So, you can make one of these oxygen absorbers very, very cheaply. You get some iron filings or you fabricate themselves. You mix that with table salt and you immediately package it into anything porous. If you were doing a great big container like sealing up a 55 gallon drum, I could say maybe using a quarter pound or a half pound of iron filings, you go ahead and throw in the salt, you throw all of that in a glass peanut butter jar, shake it up a little bit, cover it with a scrap of rag and wrap it with some tape so that stuff doesn't fall out and throw that into the barrel along with whatever it is you are preserving. If you're doing it in smaller containers like pop bottles, maybe roll a piece of paper around a pen, hot glue it, crimp the ends, throw in the powder, crimp the other end, throw it into the bottle. Whatever you want to do, use your creativity. You can use cloth, you can use paper. You can use anything as long as oxygen can sift through it. Go ahead. Just curious, this is Hal in South Dakota. Aren't the same thing? Say again, I did not hear. And in foot warmers? Oh, and in foot warmers. They are... They are similar. Okay, well somebody mentioned it once. I'm just curious. You might know. Right, there are some. Some of the MRE heating packs are similar things too. They're based on the oxidation of magnesium metal and so forth and other ingredients. Of course, that's intended to produce heat. These things probably do produce heat, but you're talking about ergs of the heat over a very long period of time, so you're never going to detect a temperature change. but they do a heck of a job on the oxygen. So, this is why old BK says never ever ever buy oxygen absorbers. They are, sometimes they are the wrong thing to use. You don't want to use them if there's moisture in the food or whatever that you're preserving. It's perfectly okay with tools and stuff. But in any event, They are ridiculously overpriced especially once you know what's in them because it's nothing mysterious and high-tech or whatnot and More often than not when you buy them at retail by the time you get them They're expended anyway, just through leakage and shelf life and all that kind of stuff. So just don't make them. They are cheap. They're easy You can you can use your your ingenuity in deciding what sort of final packaging envelope you want to use. I personally think the really, really cheap paper towels from public restrooms are perfect because the paper towels that you buy in the grocery store are way too fluffy and soft and very, very well suitable for paper towel use and not so suitable for this. But the hard brown ones are plenty porous and you walk in there and you pull off six feet of it, you roll it up and put it in your pocket. That's an awful lot of absorbers and they're harder. and more solid so it's easier to glue them or staple them or crimp them or whatever it is you want to do and that's all you need. You don't want to roll things up 20 layers thick. You're not trying to make a firecracker case. You're just trying to keep the iron filing and the salt out of the other stuff to be tidy and provide a barrier for tidiness that allows the oxygen to seep. through so you don't want to do anything super fancy or complex. You just want to keep it tidy. And in practical terms, if you get a little bit of iron filings or a little bit of salt in your food, it's not going to kill anybody. But we do like to be tidy and avoid this kind of stuff. uh... that's that's my my little speech on oxygen absorbers sorry to any uh... retailers of such things that may be listening but on this is one product that people should not be buying savior pennies for other things that those vendors provide uh... market anybody want to add anything up and talking a lot and uh... my pattern is that i run my voice out uh... if i talk for twenty minutes straight so you know you take a look at a lot of A lot of your products, you don't have to be super high tech, but most important is again be consistent for packaging and also uniformity of material that you use. So, want to figure out what your standard is. It's not really difficult. The system off the desiccant packs are, were after water and the oxygen absorbers were after O2. Both of those are enemies of our storage. And you can have the oxygen thing. Yeah, you can salvage silica gel from all the little itty bitty packets that come in pill bottles and things Or you can just buy the stuff by the pound at Wally world and once again put it into your own little op-books You know postal envelope will work. You know anything will work. You know so you know use your ingenuity Heat does reactivate silica gel. I think you need a little bit more than that to be effective. I think around 250 Fahrenheit or something is the goal for recharging those things. But you have the right idea. You can definitely, you can just heat them up in an oven and drive the moisture off and reuse them. Bear in mind that the little ones that you find in vitamin jars and things like this are little. Because they're dealing with a little bitty jar So you know you want to save every single one of those you can get use them by the handful if you're using if you're putting them in a larger container Okay, so don't be don't be stingy with them. Just you know use them like look at them like gravel You know you grab a handful and you throw it in and you're good, but yeah heating them up in the oven is certainly the technique to recharge those guys and Some of the fancier ones have a little bit of cobalt chloride added. This will turn back and forth between pink and blue depending on whether it's above or below a particular moisture threshold. That's kind of cool. Or you can just throw a little indicator strip on paper. They sell those in with the storage that you're using these things with. That'll give you an indicator of whether you're successful or not, whether you've got a leak. You know that kind of stuff, but yes yes save those things because it costs nothing to save them to throw them into a shoebox or a jar and You can recharge them with nothing more than a household oven Definitely, please get something on the shelf, but method it's going to elongate your storage You know the time and duration it you know dramatically It's so significant that it should be a priority for everybody that's listening number one is yes Nice clean organic wheat and stuff that aren't stuff hatches Hey, I think you got a much open mic. I do I just opened up the microphone because we are We got about 20 minutes left in the program a little or a little less with where we got to close with WBCC I'll say hi to the people who are listening over there We do have our end of the month drawing that we've got to do and today is the end of the month And this is the last hour. So when you guys are ready, I'm here to tell you we are ready to go Okay, you go ahead do that and we'll see how much time we have left over afterwards go ahead and now all right So the end of the month the drawings the tumbler even as we got the first one out already dead Jonathan Tyler the next one is going to be Richard Husky or Hugh Skye Think I'm saying that right. So number two is Richard Husky Hugh Skye Skye not ski. Sorry. Yeah, that was Number one is H-E-W-S-K-Y, dad. Number three? Number three is Harold Hugue. Yeah, Harold. So number three. That you can use with the 14,000 other in the tub. Mark Martinez. Martinez. Number five is the same as number one, Jonathan Tyler. Brennett Burchman. Butchman? Wait, am I saying that right? Brennan? Burchman, yeah, I think I'm saying that right. B-A-U-C-A-M-A-N. Bachman. Bachman, Bachman. There we go, Shelley corrected me. Oh, Bachman. Yeah, Brent Bachman. Brent Bachman is number six, sorry. Once again, the women are better at the sort of verbal stuff than we are. Well, she's a second. Michael Walker. Michael Walker. And that's seven. So we've got Jonathan Tyler, Richard Husky, Brennett Bachman. I missed Mark Martinez and Harold Hugue. I'm sorry, I'm trying to go down these on the list. I got them on the paper, not by the numbers. Jonathan Tyler, Richard Husky, Harold Hugue, Mark Martinez, Brent Hogue. Okay. Harold's Hogue Brent Bachman and Michael Walker And Tyler is up there twice as package number one in package number five Shelly appreciates the vote of confidence BC. She read my phone as soon as you got the ding Well, no BC BC just texted us agreeing with you BK little intro you know the last hour of the day in the week cycle for shortwave other things i want to remind people of well as he right now harbor freights running a sale they run sales all the time they have the usual flyers they send out coupons by email all this kind of good stuff they're having another one they've extended through the second of december this is one of these extended black friday sales blah blah blah This contributes to my suspicion that the retail sector is kind of soft because I don't know how many outfits I've seen extending their Black Friday sales and so on. But Harbor Freight is doing it again and we may as well mention a few of their items. They have the usual stuff. There is a 20% coupon in their flyers. They always do that. So, you know, your biggest, most expensive item, you know, that trip in the store, you use the 20% coupon. And they are offering a free little LED palm light. One of these guys that looks like a... You know it's about the size of an old-fashioned small pack of king-sized cigarettes or something and it's got LEDs on the side They're okay. I've tried those out. They're alright. They're nothing right home about but they're perfectly okay and for a free light You know free with any purchase great good stuff, but They do have a couple of items that I would point people towards. One, they are offering their 30 caliber plastic ammo can for $3 a piece. That's the sort of price that old BK was used to with the Mil-Surplus steel ones. We haven't seen that kind of price in a long, long time. You know, we old geezers get kind of fixated on the way things were when we were just getting up to speed when we were young bucks. And then time passes us by and we say, geez, you know, the system today, everything's so expensive, so on and so forth. Well, okay, fine. This is an adaptation of the system to those impulses. Injected molded plastic is cheaper than folded and welded sheet steel. I really like the steel. better. But for $3 a piece you really can't complain too much. That will do the job of keeping airtight and moisture tight. Whatever you want to store including you know the ammunition of that general size and so forth. $3 a piece for the plastic 30 cal ammo cans that's not a bad price at all. They offer a wireless infrared security detector. This consists of a little base unit that sits there and listens to the radio and squawks if it gets a signal. That parks inside your house and a little sensor that parks outside the house. The sensor takes 9 volt batteries and it is not really watertight. You want to go to work with it. You want to grab that thing out of the box and seal up all the cracks with some silicone glue so that it actually can resist rain. When you put the batteries in, you probably want to slap watertight tape over the battery compartment. Because you know the instructions on this thing say don't let it get rained on even though you're putting it outside Well, that means it has to be under an Eve or you know some sort of environmental protection So the plastic assembly of these devices is fairly cheap However, at $10 for a pair of these devices, you know, one transmitter and one receiver, that's not bad. Bear in mind that these guys come in about, what, 10 or so different frequencies to keep them separate. So you rummage around in the store and you get three of frequency five and you get two of frequency nine and so on like that. And you'll want to plan those out. You want to put a cluster of them out in the front and a different cluster out in the back so that when the different detectors go off you know that something happened in the front or in the back. But, you know, they're not bad devices. I've tried them out. They were part of my raccoon she had when I had a problem with a family of raccoons coming up on the deck and trashing everything every night. That was their idea of fun. I put these detectors out there and then I'd run upstairs and grab the air rifle and see what I could do about these guys. But they did work. And they're not hundreds of feet of radius from the detector. Don't misread the ad copy in that fashion. They're good for maybe 10, 15 feet from the detector. So if you want to play these things, you wanted to play a whole bunch of them with overlapping fields and whatnot. uh... if one of them uh... loses battery it's not a big deal and if one of them is not too sensitive somebody walks up and and just covers one of with a can will hopefully their tripping others while they're walking up attacking the first one so these are useful devices at thirty bucks apiece their horrible ripoff ten dollars apiece are pretty good deal uh... but pay attention to the frequencies marked on the outside of the package because you will want to cluster them together and match their frequencies mark if you ever played with these guys less expensive version of exactly what they were using during Vietnam War. We were talking about these during the two-hour block. Increase the range with regard to maybe even boosting the means that you don't have to increase your signal. You can actually boost the signal reception during the wire. I wouldn't have to play one of these things. I would go out there and get a half a dozen minimum. The way the original ones worked is they had simple guys. You tuned into a frequency and the look. I suspect that these are slightly different frequencies are probably all around 433 megahertz that's one of the greats that you can get a standard chip for for transmitting well also it sounds like if they're again they have five from civil you know transfer that they were using have used for a number of different frequencies for this kind of sensor net
