Alkali metals in water

Posted on

The girl child came home buzzing yesterday after a Chemistry lesson in which they got to chuck some Sodium into some water. This reminded me of that iconic Open University video where they do the same demonstration with a number of Group 1 Metals, namely Lithium, Sodium, Potassium, Rubidium and Caesium.

Don’t bother with the first bit (unless you really want to). The fun starts at about 1:06, so scroll straight through. And it’s definitely worth a minute or so of your time, so do bear with it, even when they insist on putting the equation for the chemical reaction across the screen, 1970s style.
And do put the sound on so that you don’t miss the deadpan commentary, with lines like:

You can see that things become gradually more terrifying as we go down the group.

The involuntary whistle and abrupt end to the video are perfect. It’s not like they didn’t know what was coming, and yet…

We’re going to need another beaker, Ted.

I miss those carefree (by which I mean “H&S-free”) days in the laboratory.

Puzzled

A bit of a gentle day today. I’ve been burning the candle at both ends, and simple conservation of energy dictates that the light that burns twice as bright burns half as long.

I also appear to have swallowed a book of clichés.

And after a bit of a sleepless night, I chose to have something of a day off.
Not great, but lucky to be able to have that luxury.

Anyway, I’m going to turn in another early night, but not before I have linked you to a couple of Puzzgrids I chucked up today. My lack of oomph is other people’s pleasure. Or something.

What’s Puzzgrid? Well, it’s a spin-off of the Only Connect Wall and it definitely pre-dated NYT Connections. But if you like either of those, you’ll definitely like this.

Please enjoy #92135 & #92139. They shouldn’t be too difficult, but I do always say that they’re only easy if you know all the answers. I do know all the answers.

Not an Orange Breasted Mousebird. This is an Orange Breasted Sunbird.

Just some of the wildlife we spotted at Kirstenbosch this morning, which also included a mouse, and a snake.

The snake was a Cape Cobra, and I did get some very quick shots, but nothing great. It just wanted to get away from us, and did so by quickly disappearing into a hole.

You shouldn’t be afraid of South African snakes. This one could kill you with a single bite, but don’t want to hurt you. They don’t want to be anywhere near you.

Think of it as a mouse with fangs.

Tonight: Dad’s last night before he heads home. There are plans for a nice meal out.

Extinct

More from Nathan W Pyle (you may remember him from such posts as Day 202 – Simulate Exhaustion, Coffee, and Strange Planet.

This one isn’t a cartoon, though.

But it’s a very accurate observation. (And it’s a haiku, as well.)

I’m glad that they’ve been exterminated. Quite reasonably, they give (gave?) me the creeps.
Too many limbs. And two ribcages. Just wrong.

Fit by jogging

Discovery have just sent me a “Spotify Wrapped” type thing for my exercise last year.
I did quite a lot of exercise last year.

That’s nearly one workout every day. And sure, some probably weren’t exhaustingly hectic, but then again some definitely were. And even the ones that weren’t too much of a struggle required more effort than sitting on the couch.

I did enough kms to get from SA to Ghana, but mysteriously, I never went to Ghana. [X-Files Music]

I don’t think that this number involves driving or flying. I think that this number is walking and running (I don’t do cycling).

I hit my weekly exercise goal on 43 occasions. That puts me in the top 5% of active Discovery members.
Which seems a bit much. Surely we can all do collectively better this year.

My most active month was June: probably because I enjoy exercising in the cold weather, and I did a lot of walking around Ireland and the UK.

Apparently, I really didn’t do much in September, given that I did more in November, when I was down with Covid. Again.

Not much to add. I’ve hit all my goals so far this year.
Apparently, across South Africa last year, January 17th was the most active day. Which just shows how long those New Years Resolutions last. October 28th was the least active.

Today is January 19th. And I’m still going.

Just.
