08:18 – One day down, four to go until Barbara returns home. Colin behaved pretty well yesterday, but last night was horrible. On average, every 45 minutes or so he’d jump down off the bed and go roaring down the hall to the front door, barking his head off. I’d just about get back to sleep when he’d do it again.

It’s not yet summer, but things are warming up around here. Our highs for the next week are to be around 95F (35C), with lows in the low 70’s (~ 22C). Thunderstorms are in prospect just about every day.

This morning I need to make up three liters each of Barfoed’s, Benedict’s, and biuret reagents, and 12.5 liters of Fertilizer concentrate A. Once I get those bottles filled, we’ll have all the chemicals we need to make up another 30 biology kits, and most of what we need for 60 or 70 more beyond that. And then I can get to work on making up chemicals for another batch of forensic kits.


15:57 – I just got email from Netflix saying that they’ve (finally) added season five of Heartland. Now they’re only two seasons behind. Speaking of Heartland, I’m now just over halfway through season two. With three evenings left until Barbara returns, I should get through season two and well into season three. I was considering the wild-women-and-parties thing last night, but Colin preferred to watch Heartland re-runs. He really likes hearing Amy say, “Good boy!” He thinks she’s calling him a good boy.

I now have all the chemicals made up for more biology kits. Tomorrow I’ll start on the ones I need for forensic science kits, which we’re getting low on. That includes one of my least favorite chemicals, black fingerprint powder. Our fingerprint powders use a proprietary formulation, but the white powder is a mixture of titanium dioxide, calcium carbonate, and cornstarch, while the black powder is a mixture of lampblack and graphite. The problem with the black powder is that it gets on everything and produces black smudges that are difficult to remove. I’ll fill unlabeled containers with the black powder, seal them, and then wash them to remove any remaining powder before we label them. Even doing that, we may end up with some black smudges on labels.
