11:13 – Still working on kits. I’m doing laundry. Barbara just headed out to run errands. Among other things, she’s going to pick up a couple of 120 liter bags of vermiculite, which we use as an asborbent for packing chemicals. She was also going to pick up some 1% hydrocortisone spray for Colin’s legpits, which he’s scratching raw from allergic itching. We’ve tried diphenhydramine, loratidine, and most recently chlorpheniramine, none of which work very well. But this morning Barbara found a dozen 20 mg prednisone tablets that I’d squirreled away in the freezer. She just gave Colin a quarter tab, which may be enough to knock down the itching. I asked her if I should give our vet, Sue Stephens, a call and ask her to prescribe another 30 or 60 20 mg tablets, but Barbara said not to bother. Those dozen tablets she found are sufficient for 48 doses, which she probably won’t use up in a year or two. The 5 mg dosage is very low and she seldom administers it for more than a couple of days, so we don’t need to worry about tapering Colin off.

I’m still spending spare moments designing our new kits for 2014/2015. I’m well into Earth Science, which’ll be teachable as a middle school or high school level lab course, and I’m stubbing out AP Chemistry and AP Biology. And I keep thinking that we really need to do at least a first-year level physics course.

11:13 – Barbara had a scare last night. At 1958, the phone rang. It was Barbara’s mom, who was apparently confused and feeling faint or dizzy. Barbara told her to pull her alert cord and sit down to wait for help. Her mom apparently hung up on her. Barbara ran back to get her cell phone to call the managers at Creekside to ask them to go check on her mom, and asked me to call her mom back. Barbara then headed for car to drive over there. I called, Sankie answered, and I told her who I was. I asked if she’d pulled the alert cord and she said she hadn’t. I asked if she was sitting down. She said she was standing, and then apparently dropped the phone. I shouted her name, but there was nothing but dead air. So I hung up. This was at 2003. I was about to call Creekside again when the phone rang. It was one of the managers at Creekside. He said he was with Sankie and said that in his opinion he should call 911. He asked my permission, since 911 charges several hundred dollars if they’re called out and don’t have to transport the patient. I told him that he was there and I wasn’t, so if he thought she needed 911 to call them. A few minutes later, Barbara called on her cell and said she was following an ambulance that she suspected was the one responding to the 911 call for her mom. A while later, Barbara called to say she was with her mom and the 911 responders were checking her. Apparently, they decided she didn’t need to go to the emergency room, so they left. Frances showed up around then, and she and Barbara sat with Sankie to make sure she was okay. Barbara finally made it home about 2230. I really, really hope this was an isolated incident. For a year or more, Barbara and Frances were on 24-hour call for Dutch, having to drop everything and rush over to the apartment or the emergency room. They simply can’t go through that again.


I just finished making up 10 liters of fertilizer part A concentrate, which is sufficient for 1,000 liters of working-strength solution, or 80 biology kits worth. I have 75 bottles already labeled, so I’ll probably fill those today, along with a few hundred other chemical bottles.

11:16 – Autumn is here and our weather reflects that. Our highs over the next week are to be mid-70s F (~24 C) and our lows in the mid-50’s F (~13 C).

Which reminds me of a little-known fact. One of my undergrad chemistry professors was adamant that “C” stood for “centigrade” rather than “Celsius”, no matter what any standards body said. As he pointed out, on the centigrade scale water freezes at 0 degrees and boils at 100, whereas on the Celsius scale water freezes at 100 degrees and boils at 0. So, to this day, I speak the name of the scale as centigrade rather than Celsius.

I picked up Barbara at around 1800 yesterday. I got there at 1705, just in case. I didn’t want her and Marcy to end up standing in the rain waiting for me. Colin and I are delighted that she’s home. Colin’s behavior changed while Barbara was gone. If there was one thing his mother taught him as a puppy, it was that paws require frequent washing. Ordinarily, Colin washes my front paws every chance he gets, several times in the evening while we’re watching TV and at least a couple of times in the middle of the night I’ll wake up to find him washing my front paws. And he does a good job. It normally takes him at least four or five minutes per paw. If they’re particularly dirty, he’ll chew gently as well as licking. The whole time Barbara was gone, he didn’t wash my paws even once. Last night, he started back in on washing them. It took him much longer before he was satisfied, seeing as how they hadn’t been washed for a week. He finally called it done and went to sleep again, but he woke up later and did a second pass on them.

I’m still working on stubbing out the manual for the EK01 Earth Science Kit. Public schools teach earth science as both a middle-school course–usually grade eight–and as a high-school level course. I think the middle-school level courses are pretty much wasted. The rigor is typically very low, and the expectations correspondingly so. Few colleges even consider the middle-school level science courses in a student’s transcript, and rightly so. So I’m going to do this manual and kit at the high-school level, if not first-year college physical geology. There’s nothing there that a bright 14-year-old shouldn’t be able to handle.

But “earth science” as taught in most schools isn’t just geology. In fact, the course is often named “earth and space science”. So, although there’s no need for a kit for astronomy, I think I’m going to include an astronomy lab component. Of course, for astronomy, “lab” is really observational astronomy. I’ll keep the “labs” simple and try to require only a binocular or perhaps an inexpensive telescope like the 4.25″ Orion StarBlast. Or perhaps I’ll just make the kit cover geology labs and perhaps one or two on topology and so on.

I frequently hear from homeschool parents with kids who are destined to major in STEM. They’re concerned because four years of high school gives them time for only four lab science courses, unless they double up. But there is an alternative, and it’s what I did when I was that age. I spent summers dividing my time between playing tennis and doing science. In other words, I did a full year’s worth of science every summer. A semester is 18 weeks or 90 school days, basically a quarter of a year. Kids typically do classes 180 days a year, or half a year, spread over two-thirds of the year. That’s roughly 500 school hours per semester, or 1,000 school hours per year. But homeschool parents have complete scheduling flexibility. Trying to do four full semesters a year would be really pushing it, but doing 2.5 or even three is within the realm of possibility. Assuming a summer break of roughly 12 weeks and running summer school three hours a day five days a week is sufficient time for the equivalent of one full-year course or two one-semester courses over the summer. If that time is devoted to science, that means a student has time in grades 9 through 12 to take eight full years of lab science rather than only four. Even at only 1.5 hours per day five days a week, that’s six years of science instead of only four.

That’s time to do two full years of chemistry, two full years of biology, and two full years of physics. And if the kids do two semesters’ worth of science every summer rather than one, that leaves time for four full semesters of additional science. Things like microbiology, molecular biology, organic chemistry, analytical chemistry, biochemistry, physical chemistry, an engineering course or two, and so on. Knowing what I know, if I were 14 years old now, that’s what I’d do. My real goal would be to skip undergrad entirely, be accepted into grad school at age 17 or 18, and get my doctorate at age 21 or 22.

07:16 – Barbara gets back today. Colin will be delighted when she walks in the door. So will I.


11:50 – Ruh-roh. It looks like I’ve come to the feds’ attention.

I got a forensic kit order this morning. When I ship kits, I send email that provides supplemental information and asks purchasers where they heard about the kits. So, here’s the response I just got…

[…] I actually ordered the kits for my senior level high school forensic science class. I attended a forensic conference in California where an ATF agent did a power point presentation on drug analysis. He used one of the drug labs in your book to analyze over-the-counter drugs. I already purchased your book last year. There are a lot of great labs in the book that can be done in the classroom. I teach biology also and will be ordering the biology book at the end of this year.[…]

11:28 – Barbara gets back tomorrow. I can’t wait. Colin had the squirties yesterday and overnight, not to mention barfing up his dinner on the foyer rug, so I’m running on very little sleep.

Barbara called a few minutes ago. The tour bus had made a stop at a Cabellas, so Barbara was walking around the guns and ammunition section. Geez. The last time I bought a box of 100 .45 ACP ammunition at Wal*Mart, it was something like $29. She said Cabellas had the same box, but it’s now $78. She said she wasn’t comfortable buying ammunition, which was fine with me since I have no idea whether it’d even be legal to transport it interstate on a tour bus. She did say she could pick up a couple of shotguns, but I passed on that as well. I told her about Colin’s squirties problem, and of course she was very concerned. But it seems to have cleared up today, so I told her not to worry about it.

I’m working today on designing an earth science kit. Kit design is always an iterative process, adding stuff tentatively and then taking it out later when it turns out it’s not worth the cost because there are cheaper ways to accomplish the same thing. And the whole time I’m roughing out the lab manual, adding stuff here and removing stuff there.

08:34 – Only two more days until Barbara returns. Colin is getting impatient. Since Sunday, Barbara’s been in the Michigan UP area, first at Mackinac Island and yesterday at Sault Ste. Marie. She hasn’t had a cell signal since they arrived at Mackinac, so I called her last night at her hotel just to make sure everything was okay. She said everything is fine and that she and Marcy are having a great time.

The morning paper reports that Duke Energy has joined a large and growing list of big companies that are eliminating retiree health insurance. Duke will now pay a fixed amount toward Medicare supplement policies for its retirees. I expect this phenomenon to snowball over the next few years. Eventually, all private retirees and many local and state government retirees will find that their only option is Medicare, with their former employers perhaps paying something towards a supplemental policy. Eventually, I expect federal government and military retirees will also be lumped into the Medicare system. This is just an early sign of the creeping defaults government will make on unsustainable promises.

Kit work continues. I need to inventory our bottle supply and put together a PO for more bottles and caps once I figure out what we’re short of.


12:07 – As it turns out, we’re in a lot better shape on bottles than I thought we were. I found a couple of cases that I didn’t realize we had. That gives us enough empty bottles for another 100+ kits–in addition to the labeled bottles we already have in stock, another 100+ kits worth–so I can put off ordering bottles and caps for another couple months.

I did start transferring cases of bottles from the manufacturer’s packaging–large plastic bags inside cardboard boxes–to 66-quart translucent plastic bins. Those stack a lot better than the boxes and make it easy to see how many bottles of each type we have in stock with just a glance. I need to pick up another six or eight of the 66-quart bins the next time we’re at Home Depot.

09:47 – Barbara’s been gone 96 hours. We miss her. I told Colin this morning that she’d be back in only three more days. That seemed to satisfy him.

The plastic bottles we order in bulk come in cases of 1,100 to 1,650, depending on the size of the bottle. They’re packaged loose-filled in large cardboard boxes with a large plastic bag inside to protect the bottles from dirt. The 30 mL glass bottles are different. They come in “cases” of 168 bottles, which are shrink-wrapped. I hate that packaging, because as soon as I cut the shrink wrap I end up with a loose pile of breakable bottles. I wish they’d package them in cardboard boxes with cardboard dividers to protect the individual bottles.


Katie sent me these two images yesterday, taken in Fort Collins, Colorado where she lives and works.

Hi Bob,

Here are a couple flood pictures (before and after). The first one was taken Friday and the second one was just a few minutes ago.

These were taken right by our work on the path we take our daily walks!

Thought I would share since we were talking about it yesterday.

11:57 – Those who follow RCC superstitions should be aware that contact with “holy” water can be hazardous to their health: Holy water in Austria is contaminated, unsafe to drink, researchers say

Although the researchers limited themselves to churches and other religious sites in Austria, it seems likely that the problem is universal. Many people don’t wash their hands after using the bathroom, so the bacteria and viruses on their hands–including potentially deadly coliforms and other pathogens–are transferred to the ‘holy” water. So, the next time you think about touching “holy” water, you might want to think again. Either that, or boil or otherwise sterilize the stuff before you handle it.

09:50 – Barbara’s been gone 72 hours. So far, Colin and I are making do. Only four more days until she returns.

I called AmEP yesterday afternoon just to make sure that Katie was okay. She said she and her husband are fine, as is the business, but that much of Fort Collins and the surrounding area is a complete wreck. She was off Thursday and the business was closed Friday. She said it took her about two and half hours yesterday to drive the two or three miles from their house to the office. Almost all of the bridges are out, and the traffic was a bumper-to-bumper parking lot. But they’re still operating normally, taking orders, receiving shipments from their suppliers, and sending out shipments to their customers. Colin barked while were talking, and I told Katie that that was my Border Collie assistant. As it turns out, Katie also has a Border Collie. She got her when she was in college, and the BC is now 13 years old.

I told Katie that our next science kit would probably be earth science, and that I wanted to include rock and mineral specimens. AmEP has dozens of different rock/mineral kits in their catalog, but as I told Katie I fear single-sourcing anything. I’d hate to have a standard kit that requires a product that the vendor might discontinue without notice. She said that their rock/mineral kits are an “evergreen” product for them. They sell them in large numbers and have been doing so for years. They build the kits themselves rather than importing them from China or wherever. They actually employ a geologist and they own the quarries where they get their rock specimens. Katie said they’d be happy to do a custom kit for me, or if I preferred they’d sell me the stuff in bulk. So, for example, I could order 50 pounds each or whatever of 1″ chunks of 25 different rocks and minerals and build the kits ourselves.

09:25 – Barbara’s been gone 48 hours. Surprisingly, Colin seems to be doing pretty well. He’s not pestering any more than usual, nor demanding that I Do Something about Barbara being missing. Like most Border Collies, Duncan and Malcolm were one-person dogs, and that person was Barbara. They tolerated me. When Barbara and I were both out of the house and I came home alone, Duncan and Malcolm would bark like crazy to celebrate Barbara’s return. When they saw it was just me, they’d say, “Oh, it’s just you” and go back to watching/listening for Barbara’s return. Colin seems to be a two-person Border Collie, and he’s happy as long as at least one of us is with him.

I ran myself flat out of the CK01B chemistry kits this morning. Fortunately, I have everything I need for a dozen more sitting on the shelf, so it’s just a matter of boxing them up. We’re also down to four of the BK01 biology kits as of this morning, so I’ll get another dozen or two built over the next couple of days. Come to think of it, I’m out of the iodine solution, so I’ll have to make up another two liters of that and fill bottles before I can build more kits.

Our thoughts are with the flooding victims in Colorado. I just read an article that mentioned that evacuations were voluntary, but those who decide not to evacuate their homes are being warned that they could be without water and power for weeks to months. Given that many roads and bridges have been utterly destroyed and will require months to years to be rebuilt, those folks may literally have to hike out if they change their minds. And, of course, emergency medical care will be unavailable or at least very slow in arriving.

08:52 – Barbara’s been gone 24 hours, and Colin and I are already descending into barbarism, filth, and squalor. Last night, we stalked, pounced, and killed our dinner and ate it raw. That frozen Stouffer’s chicken and brocolli pasta bake never knew what hit it. It was kind of crunchy, though. Next time, we may heat it first. All of Barbara’s training is not lost on us, however. I’m doing a load of laundry as I write this, and later I’ll clean the toilets.

I have all but two of the solutions I need for a new batch of 60 biology kits made up, and most of the bottles filled. I’ll make up three liters each of the 6 molar hydrochloric acid and 6 molar sodium hydroxide solutions today and try to finish bottling everything. Tomorrow I’ll build a dozen or two biology kits and then get to work on what I need to build more chemistry and forensic kits. As expected, kit sales have started to tail off a bit. Some days, we ship six or eight kits and other days none or one. We’re still averaging about three a day, but that’s starting to decline. In October/November, we’ll probably average 1.5/day and then jump back up to around two a day in December.


10:18 – I’m getting a bit concerned about Katie Dugan, who’s my rep at one of our wholesalers, American Educational Products. She’s a delightful young woman, and I talk with her regularly, most recently a day or two before the flooding started. AmEP is in Fort Collins, Colorado, which until this morning I thought was not one of the worst-affected areas. The news reports kept talking about Boulder, but this morning I saw one that mentioned that Fort Collins and its county have more than 350 people unaccounted for, which is the bulk of those unaccounted for. I hope Katie and her new husband are okay.
