07:25 – Barbara’s hoping her dad will be released from the hospital today, but we won’t know until later today.

Illustrated Guide to Home Forensic Science Experiments: All Lab, No Lecture is now complete and off to our editor. It’s due to hit the bookstores on 22 August, which means we have to have Forensic Science kits ready to ship before then.

Yesterday I called the guy from whom I bought the 250 g of iodine to see what other chemicals he carried. Apparently, he specializes in iodine and iodides. I told him that I was surprised that he was openly selling iodine on eBay in violation of DEA regulations, and he said that indeed he’d recently been contacted by the DEA and had ended up applying for a license to sell iodine. When I said that I was a bit concerned that ordering 250 g would get me on a DEA list, he said not to worry about it. Apparently, the limit is 300 g of iodine per month. I already had about 100 g in stock, and 350 g is probably more than I’ll use in a year.

08:10 – Barbara’s dad is still in the hospital, and probably will be for the next couple of days. Barbara said he’d lost about four pounds (~ two kilos), all of which was water weight. They’ll continue to dry him out and then have some other tests they want to run.

I spent much of yesterday costing out the forensic science kits. I had to do that before the book is finalized, because I didn’t want the kit to end up having to be priced at $300 or $400. The goal is $200 or less. Eyeballing it, it looks like we’ll be able to do that. Based on the amount of stuff that’ll be in the kit, it looks like we may have to go to a large flat-rate box rather than a regional-rate box B, which puts the shipping cost at about $15, versus an average of maybe $10 on the chemistry and biology kits, but that’s doable. One way or another, we’ll still bundle in free shipping because people hate to have shipping charges separate from the product price.

Geez. By 0800 this morning, I’d already shipped two kits, one chemistry and one biology. This is making me nervous. We get a nice batch of kits ready. They’re sitting there, all stacked up nice and pretty. And then people go and order them, and we watch our stock dwindle. Oh, well. I guess I’d better get used to it. From now until maybe October, we’ll be shipping a lot of kits. We can rest then.


10:34 – I love how some vendors try to encourage people to upgrade from the free shipping option. I ordered a case of 10 mL oral syringes on Tuesday, and chose the free shipping option with 7 to 10 day delivery. I wasn’t in a huge hurry, so I decided that was fine. I just got a notification from the vendor with a UPS tracking number. The shipment is scheduled to arrive tomorrow.

“Free” shipping used to be an inducement to increase order size and prevent abandoned shopping carts, but it’s come to be expected and just another cost of doing business. LL Bean’s new free shipping policy may be the final nail in the coffin of charging for shipping separately. Bean now ships essentially all orders for free, regardless of number of items or price. I can order one $3 item and Bean ships it for free.

I never had any intention of charging separately for shipping. Fortunately, that’s easy for us because our minimum order is currently $160, the price of one chemistry kit. The only small orders we receive are replacement orders for spilled chemicals, broken glassware, and so on. On those orders, of which we’ve received exactly one in the last year, we may end up breaking even or worse, but again I consider that just a cost of doing business.

06:57 – I’m still working heads-down on the forensics book, putting together consolidated equipment/chemicals/specimens lists from all of the lab sessions. I should finish that up today or tomorrow, which means the manuscript is complete. I’ll then go back and do a quick clean-up pass, shoot more images, and so on.


10:01 – Barbara took her dad to an early appointment this morning with his doctor. She called about 9:00 to say that the doctor wanted her dad to go to the hospital. He has problems with fluid accumulation, which they’ve been treating by limiting his fluid intake and having him on a regimen of Lasix or some other loop diuretic. This morning, the edema was bad enough that the doctor thought IV diuretics were needed, so Barbara took her dad over to the hospital. I’m not sure if they’ll admit him or just treat him and release him. Barbara and her sister have been run ragged recently dealing with medical emergencies. I hope the hospital sends Dutch home today. Hospital stays are very hard on their parents, of course, but they’re also hard on Barbara and Frances. It’s fortunate that there are two of them to share the hospital visits and running around on errands for their parents.


13:41 – Barbara called to say they’ve admitted her dad to the hospital and he’ll be there several days. I guess their mom is going to stay with Barbara’s sister. It doesn’t sound like Dutch is in any real danger, but they have to get him dried out before they can send him home. He has a lot of fluids accumulated in his tissues, particularly his legs. The real worry, of course, is that the edema also occurs around the heart, causing congestive heart failure.

Here’s something weird. I just shipped a kit to California, which is in USPS zone 8, the most expensive zone. The kit, as all of them are, was in a USPS Priority Mail Regional Rate Box B. It cost $14.62 to ship. The weird part is that I could have used a USPS Priority Mail Large Flat-Rate Box–which is larger than the RR Box B and also has a weight limit of 75 pounds versus 20 pounds for the RR box–and it would have cost $14.61, a penny less. Very strange.


16:19 – The reason we assembled only 18 chemistry kits last weekend is that we ran out of one component, the 10 mL oral syringe. I’d been ordering those in bags of 100, and was just about to reorder two bags when I realized that was foolish. So I ordered a case of 500 instead. It’ll be a while before I need to reorder those. Our stock of chemistry kits is already dwindling fast, so we need to get more assembled in the next week or two. Other than the syringes, we have everything needed to assemble another dozen in a few minutes, but that’s not going to keep us for long. Once I get this forensics book put to bed, I’m going to order components for another 90 or 120 (we print labels in sheets of 30) chemistry kits and the same number of biology kits and get to work on making up and bottling the chemicals for them. While I’m at it, I’ll order components for 60 or 90 forensic science kits. Or maybe more.

07:17 – We’re back in stock and shipping chemistry kits, so I’m back to working heads-down on the forensics book. I’ll finish the text later this week, which leaves me a week to go back and clean things up, shoot more images, and so on.

08:00 – Barbara’s mom came home from the hospital yesterday, and seems to be doing much better. Both of Barbara’s parents have follow-up visits scheduled with their doctors, and I suggested that Barbara talk to the doctors about prescribing supplemental oxygen for her parents to keep at home, preferably an oxygen concentrator rather than something that requires oxygen tanks.

We’ll finish putting together a batch of 18 chemistry kits this afternoon, and resume shipping them tomorrow. Meanwhile, I’m still working on the forensics book.

09:07 – I finished writing the last of the forensic book lab sessions yesterday, although I still have to actually do the lab. It’s the one on using molybdate to assay soil phosphate concentrations. I’m pretty sure it’ll work as written because it’s widely used in the real world, but I still have to be certain.

Barbara and I are building a batch of chemistry kits this weekend so that we can ship backorders Monday. We’ll put together 30 kits, although only 18 of them will be ready to ship because we have only 18 of one of the subassemblies built. Still, that’s enough chemistry kits to fill backorders and carry us probably into next month.

Barbara’s mom should be going home from the hospital today, we hope. She’s doing much better. Barbara was glad to be home, after spending several days and nights away. Colin and I were delighted to have her home as well. Barbara and I had dinner with Mary Chervenak last night at a little Greek restaurant. I always enjoy spending time with Mary. She’s smart and outspoken, so the conversation never lags.

07:52 – Barbara slept at her parents’ house Wednesday night and then went into work yesterday after visiting her mom at the hospital. She left work early to go back over to the hospital to visit and then have dinner with her dad. Her mom is doing better. She may or may not be released today. Barbara slept over at her parents’ house again last night. She’ll take her dad over to the hospital this morning and then head in to work. Colin and I have been scrounging meals as best we can. In the evenings, we’ve been re-watching series one and two of Heartland.

Two weeks left until the final deadline for Illustrated Guide to Home Forensic Science Experiments, and it looks like we’ll make it with time to spare. That’s good, because we definitely need to spend some time this weekend rebuilding our stock of chemistry kits.


13:12 – It’s looking increasingly possible that the breakup of the eurozone won’t result from the Greek government (such as it isn’t…) defaulting, but instead from a run on Greek banks. Greeks are now lining up outside banks to withdraw the entire amounts in their accounts. Ordinary Greeks perceive, rightly, that their money is much safer under their mattresses than it is in a Greek bank. One day soon, Greece and the world will learn with no notice that Greece is no longer in the euro, but has converted back to the drachma or whatever they choose to call their new local currency. When that happens, Greece will institute capital controls even harsher than those now in effect, to prevent euros from fleeing Greece. (Smuggling literally suitcases full of euro notes is now common; a lot of that is stopped at the borders, but I suspect most of it gets through.)

When the banks open that Morning After, Greeks will find that all of their euro deposits are now are now drachma-denominated, no doubt at an exchange rate of 1:1. Of course, despite the fact that the euro will soon itself be in free-fall, one drachma won’t actually be worth anything near one euro. When Greece adopted the euro a decade ago, the drachma:euro exchange rate was, IIRC, something like 350:1. And Greece was at that time in a lot better financial shape than it is now. My guess is that the drachma:euro exchange rate will soon be at something like 1,000:1, if not 10,000:1. And then we’ll see the real inflation taking hold, just as it did in Weimar Germany. People will have to haul a wheelbarrow full of overstamped drachma-euros up to the counter to buy a cup of coffee.

But for now, Greek banks are paying off euro depositors in euros, of which they are embarrassingly short and getting shorter. At this point, there isn’t technically a run on the Greek banks, because they’ve been able, so far, to meet depositor demands. But with Greek depositors withdrawing euros at a net of something like 5 billion a week and increasing fast, that’s likely to change very soon. Remember, neither Greek banks nor the Greek government can issue euros. They print them, yes, but only as authorized by the ECB, which isn’t authorizing them to print any more. In the absence of authorization, any euros that Greece prints will legally be counterfeits. Not that I’d expect that to prevent them from printing those euros. Desperate people take desperate actions.

So ordinary Greeks now have two priorities. First, get their euros out of Greek banks. Second, get those euros out of Greece. And who can blame them?

07:42 – We had a brief power failure Monday during the deluge. Our cable modem isn’t connected to a UPS, and Barbara commented that evening that since we had no phone service during a power outage she was going to start keeping her cell phone turned on. (In the past, she kept it off except to make calls or when she was expecting a call.) She asked me to remind her to start doing that, which I did yesterday morning.

Talk about a timely decision. About 6:15 p.m. yesterday, Barbara’s sister, Frances, called to tell me that their mom was on her way to the hospital in an ambulance. She’d been feeling ill for a couple of days, and was having trouble breathing. Of course, she didn’t want to bother Frances or Barbara, so she hadn’t said anything.

Barbara was stuck at the ballgame, because she’d left her car in the parking deck at work and ridden over to the game with a friend from work. I told her that from what Frances had said, her mom didn’t appear to be in any immediate danger now that she was at the emergency room. Barbara got over there as quickly as she could, and called later to say that her mom was stable and that they were waiting to see if the hospital would admit her or just pump her full of antibiotics and send her home. She kept me updated through the evening, although there wasn’t much to tell. They were just sitting waiting to find out what was going to happen.

Finally, around 12:30 or 1:00 this morning, Barbara called again to say they’d decided to admit her mom. Barbara didn’t want her dad, who turns 90 in July, to be at home alone overnight, so she decided to sleep over at her parents’ house. She’ll either go in late to work today, or take the day off, depending on what they find out this morning. If she goes into work, she’ll have to come home first to shower and change. I’m going to suggest that she pack a small bag with work clothes, nightgown, toothbrush, and so on, and keep it in her car just in case something like this happens again.

At this point, all we know is that Barbara’s mom has a nasty lung infection, possibly pneumonia, and that they have her on strong antibiotics. We’ll find out more this morning, no doubt. And poor Colin has no idea what’s going on or where Barbara is.


For the last couple of months, I’ve been working heads-down on the forensics book, while I watched our supply of finished science kits dwindle. I knew this would bite me. The good news is that we got four chemistry kit orders yesterday. The bad news is that we had only three finished kits in stock. So now we’re in a backorder situation until we can get more kits built. We’re waiting on one component, which I didn’t get ordered as quickly as I should have due to being busy with the forensics book. That component will arrive tomorrow, and we’ll build another couple of dozen kits over the weekend and resume shipments next Monday.

07:35 – I finished the group on impression analysis yesterday and got started on the group on gunshot and explosive residues analysis. I had intended to include with the kit tiny specimens of firearms propellants (smokeless powder, black powder, Pyrodex) and explosives (dynamite, RDX, PETN, and so on). By “tiny”, I mean specimens of maybe 50 mg. Call it a tenth the size of an aspirin tablet. I was surprised to find that it’s illegal to mail these things. Not just under the Small Quantity Exemption, but period.

Fortunately, I checked the SQE rules. Until now, all of the hazardous materials I’ve been including the kits has fallen under paragraph 334.2(a) or 334.2(b), which qualify up to 30 mL or 30 g of material, respectively, for shipping under SQE. Paragraph 334.2(c) exempts “1 g (0.04 oz) or less for Division 6.1 (Packing Group I) materials”. I wasn’t sure what was included in Class 6 until I looked it up. It turns out to be “Toxic substances and infectious substances”. Alas, explosives (including firearms propellants) are in Class 1, for which there is no SQE (or ORM-D) waiver. That means it’s simply illegal to mail Class 1 materials, no matter how small the quantity. So I’ll have to fall back on telling readers to get their own specimens, which actually isn’t as difficult as it seems at first glance.

Barbara and I have started watching the shortened season three of Crossing Jordan on Netflix streaming. (The actress who plays Jordan was pregnant, which resulted in a season of only 13 episodes.) Fortunately, I happened to notice a post on a forum that mentioned that NBC had run season three not just out of order, but *really* out of order. So, instead of watching the episodes in the order they were broadcast, which is the order that Netflix streaming has them in, we’re watching them in the order they were intended to be broadcast:

1. episode #13
2. episode #7
3. episode #3
4. episode #1
5. episode #12
6. episode #2
7. episode #4
8. episode #9
9. episode #5
10. episode #6
11. episode #11
12. episode #8
13. episode #10

08:26 – Barbara is cleaning house this morning and then heading off to her parents’ house for lunch. She’ll make a small Costco run on her way home.

I’m still working on the impression analysis lab sessions. Once I finish this group, all that remains are the groups on gunshot and explosives residues, forgeries and fakes, and forensic biology. Those and the front matter. I’m hoping to finish all of those with several days to spare before the 31 May deadline so that I can go back and do some polishing before submission and maybe even add a lab session or two.

I’ve been issuing purchase orders for materials for the forensic kits as I finish each group of lab sessions, so I’ve already accumulated a lot of stuff. The only exception is the chemical orders, which I’ll combine once I know everything I need to order.
