07:47 – Barbara and I have started watching another good Canadian series on Netflix streaming. It’s Bomb Girls, set in a Toronto munitions plant in 1941. With one jarring exception, their technical advisors have done a good job. That exception was a scene that showed the girls sitting around on break (outside the plant, of course) smoking cigarettes. I almost choked on my Coke. The cigarettes they were smoking were filter tips, which didn’t become common until about 15 years after that scene was set. Also, some of the slang seems a bit anachronistic to my ears. For example, the girls use the phrase “head in the game” more than once.

But the tech advisors did get a lot of subtle things right. For example, there’s an accidental explosion and one of the survivors comments that the smoke was black instead of white. The girls fill shells with amatol, which is a mixture of TNT and ammonium nitrate. TNT is oxygen-deficient and produces black smoke when it detonates. Ammonium nitrate is oxygen-rich, and causes properly-blended amatol to produce white smoke when it detonates. So it would seem that the accident was not the fault of the girls who were filling the shells, but of the people who made up the amatol blend. I checked all this against a book I just happen to have on my shelves, the 1941 edition of Chemistry of Powder and Explosives. It’s a great reference resource for anyone who happens to be running a munitions factory in 1941.

Work on science kits continues. UPS showed up yesterday with my case of 60 Sterilite plastic shoe-box bins, which are already unpacked and in use as assembly bins.

12:28 – Back when we incorporated and started selling science kits, one of the first things I did was contact various wholesalers that we intended to use and ask them about credit terms. Most of them pretty much automatically granted $1,000 worth of trade credit, which was more than enough at the time.

Since then, I’ve started paying all of our minor vendors and all but two of the major vendors by credit card. It’s quicker and cleaner. I don’t have to write and mail checks. And our AmEx card gives us a kick-back on all purchases, so it makes sense to use it.

The two major vendors don’t accept credit cards, so I do the PO/check thing with them. Both authorized $1,000 of trade credit when we established accounts with them two years ago. One of them is pretty flexible. I mentioned Katie the other day. When I asked her early on how rigid they were about the $1,000 limit, she said not to worry about going over it within reason. She said if I ordered $1,500 or $2,000 worth of stuff or even more that probably no one would care. She said that if I issued them a PO for $4,000 or $5,000 their credit department would probably flag the transaction. The other vendor is much more rigid. They’ll accept POs up to $1,000, not including shipping (which can be significant, particularly for glassware orders), but that’s as far as they’ll budge. And until I’d paid outstanding invoices, which I do on receipt, I couldn’t order any more stuff from them, unless I pre-paid. Cutting a check for items I hadn’t yet ordered is a pain in the butt in terms of record keeping, so I just never did that.

None of this was a problem before. The typical PO I issued to that vendor might be for $600 or $800, and I seldom issued more than one or two a month. But with our business ramping up fast, I could see that it’s going to become a bigger problem. So I called and spoke to the owner this morning and asked him if he could increase my credit limit. He asked how much I wanted. I told him I was looking at a PO for $1,800–just one line item was for over $600–and trying to figure out how to prioritize items to get the PO under $1,000. I told him that our business was ramping up fast and issuing so many sub-$1,000 POs was going to be a pain in the butt, both for us and for them. So he raised our credit limit to $2,000 and said to give him a call in a few months about raising it further.

08:59 – We started watching The Grand last night on Netflix streaming. It’s set in an English hotel, with the first episode opening on New Year’s Eve 1919. The cast is good, as are the writing and production values. It’s reminiscent of Upstairs, Downstairs. The one thing I found jarring was that more than once they had characters laughing and joking about WWI. In 1919, that wasn’t a subject for levity. Britain had just lost literally most of a generation of its young men, and nearly every family had lost a young man killed, blinded, or crippled in the war. If not more than one. The scale of the slaughter was almost inconceivable to us today. On the worst day of the Battle of the Somme, for example, there were more men killed than the US lost during the entire Viet Nam war. And that battle went on for months, with more than a million total casualties. No joking matter.

I got email Sunday from a homeschool mom who really wanted to do a forensic science lab course, but her budget wouldn’t stretch to $247 for our FK01 forensic kit. She asked if there was any way we could break up the FK01 kit into smaller, less expensive kits. Hers was by no means the first similar email I’d gotten, and I was already thinking about doing exactly what she wanted. I decided to break up the FK01 kit into three kits:

The FK01A Core Forensic Science Kit sells for $165, and includes the specialized equipment, chemicals, and specimens needed to do the 25 lab sessions in the first six groups in the book. The other two kits require the FK01A kit if the user doesn’t already have the equipment and chemicals on hand. The FK01B Forensic Science Kit Supplement 1 sells for $51, and includes the specialized chemicals and specimens needed to do the 7 lab sessions in the Forensic Drug Testing and Forensic Toxicology groups in the book. The FK01C Forensic Science Kit Supplement 2 sells for $79, and includes the specialized chemicals and specimens needed to do the 7 lab sessions in the Gunshot and Explosive Residues Analysis, Detecting Altered and Forged Documents, and Forensic Biology groups in the book.

10:52 – Barbara called earlier to say they’d had an offer on their parents’ house. Their agent suggested they counter-offer, but Barbara thought the amount he suggested was a bit high, in particular because the latest real estate valuation reduced the tax value of the house by 20%. I suggested that they split the difference on their counter-offer between the listing price and the price offered. On the one hand, they don’t want to leave too much money on the table. On the other, they don’t want the potential buyer to walk away and end up having the house sitting on the market. On the gripping hand, homes are starting to sell a lot faster than they had been.

Last week, I ordered 360 glass Petri dishes, all my vendor had in stock. UPS delivered them about 6:00 last night. As usual with UPS, the boxes were a bit banged up, so I was a bit concerned. I’d ordered 100 of the same Petri dishes earlier, which Barbara packed last weekend into groups of three, padded with bubble-wrap. Of those 100, there were two cracked. A 2% breakage rate is no big deal. Almost any glassware order has some breakage.

The problem is, it’s not convenient for us to discover the actual amount of breakage because that involves unpacking every box and examining each Petri dish. The boxes are small cubes, each with four stacks of five Petri dishes, and having to repack undamaged dishes would be time-consuming and inconvenient. So I called Katie, who’s our rep with that vendor, and explained the problem. Ordinarily, vendors expect buyers to report damage or shortage quickly, usually within one to three days of receipt, but that obviously wasn’t going to work. Katie understood our problem and said just to keep a running total of breakage when we pack up the dishes for kits. She’ll issue a credit to apply towards the next order.

I also suggested to Katie that they contact the manufacturer about improving their packing. It’s a long boat trip from China, and the only protection they use within the boxes of 20 is a sheet of tissue paper between the halves of a plate pair and another sheet between plate pairs. That’s no real protection against breakage, and I suggested to Katie that they get the manufacturer to start using thin sheets of bubble wrap between halves and between pairs. If that means the boxes have to be a little larger and the cost of the plates a little higher, fine. Better that than having to deal with breakage.

09:11 – We’re getting near the end of all three series that we’re currently watching on Netflix streaming, so it’s time to start sampling a few of the 150+ other entries in our Netflix instant queue. One of the series that we’re about to finish is Rescue Me, Denis Leary’s program about FDNY firefighters. That series is excellent across the board: great writing and an excellent cast. There’s not a weak member in that cast, but Barbara and I agree that one of them stands out even among that superb group. Callie Thorne, who plays Sheila Keefe, is stunningly good. She can do more with a raised eyebrow than most accomplished actresses can do with a Shakespeare soliloquy. We’re looking forward to watching her in other series.

Speaking of excellent TV series, the Canadian series Heartland reaches a milestone this evening, when its 100th episode is broadcast. Heartland is only the second Canadian one-hour drama series ever to reach 100 episodes. It’s also, along with Rescue Me, one of very, very few series I’ve ever rated five stars on Netflix. Alas, Netflix has only the first two seasons and the first 14 of 18 episodes in series three.

Meanwhile, I’m currently running an experiment in the kitchen. The biology and life science kits include a packet of lima bean seeds. The other day, I was about to order 5 pounds (2.3 kilos) of lima bean seeds from one of my on-line vendors when I was struck by a cunning plan. Those vendors typically charge $25 plus shipping for 5 pounds of lima bean seeds. But I can get 5 pounds of dried baby lima beans at the supermarket for $8 or so. So when Barbara made a quick stop at the supermarket yesterday, she brought home a one-pound bag. I planted five of those seeds in a cup of vermiculite, which is now sitting in the dining room, where it gets lots of morning sun. I’ll keep an eye on them for the next week or ten days. If they germinate, and there’s no reason why they shouldn’t, we’ll just use lima beans from the supermarket in the kits. The cost savings would be pretty minor, maybe $0.10 per kit, but we do everything we can to keep the price of our kits as low as possible.

10:49 – The house just resounded to my Quack of Triumph. (Being a Linux guy, I quack rather than roaring.) A few months ago, I noticed that our washing machine was agitating intermittently. I ordered a replacement agitator subassembly with dogs a couple months ago. I think it cost $14 or something like that. As it turns out, I could just have ordered four dogs for about $3, but I’m just as happy to have the new agitator subassembly installed. As Barbara said, that should last the remaining life of the machine. It took me all of five minutes to do the repair, and four minutes of that was finding the correct socket and a long enough extension for my 3/8″ ratchet.

Which got me to thinking of just how valuable the Internet is, even in invisible ways. I started by searching Google for something like “agitation problem” “whirlpool washing machine” and got a bunch of hits. Among those were several on YouTube, one of which illustrated the entire process of replacing the agitator subassembly on my exact model of washing machine. Then I used Google to find the correct part number and find a good price for it, and order it. The next day, it showed up. Of course, it’s been sitting on the dryer for a couple of months waiting for me to get a round tuit, but the point is that I could have discovered the problem one day and had it fixed the next. That’s probably as fast or faster than making a service call, and certainly a whole lot cheaper. Before the Internet became what it’s become, I could still have made the repair, but it would have taken me at least a couple hours to find out what part I needed, check to see if it was in stock locally, drive over and buy the part, and make the repair. Thanks to the Internet, this kind of efficiency happens millions of times a day in one way or another.
