S-trap / P-trap (Eg in sinks and toilets)
And zip ties 👍
Pretty much anything with an interplay of water and air pressure fascinates me. Someone else mentioned siphons. I’ll mention diving bells and bongs.

My not-vented s traps are not impressive
String/rope. With a couple of knots, loops and tension you can make a lot of things with it.
Wheels are pretty cool
Lathes. You spin a thing and cut it, which sounds unimpressive, but from there you can bootstrap to pretty much all modern technology.
Or, alternatively, you can bootstrap into a fine red mist as you get stuck to it and violently flung about
Lathes rule
Yes, when bootstrapping, tuck in your bootstraps.
To add a bit of detail, it comes down to circles being nice, simple geometric objects, and an assembly of metal with contact points being capable of way more accuracy than you’d first expect.
Bootstrapping the first lathe is harder; most likely some historical elite master craftsman was able to make one freehand, and future ones derived from it. We still have the one Vaucanson made that way, although it sounds like it was a one-off. David Gingery wrote a book on the topic, but he still assumes you have a power drill and a ready-made threaded rod.
Rock.
I like to get all up in my snuggie. Get a little weird.
Sleeping pad shnozzle bags (pump sacks).
Turbine style desk fans. They push wind very fast.

This toaster:
Might as well link the Technology Connections video already.
Yes, it’s an 18 minutes video on a 1950s toaster, you can thank me later.
I bought one of these toasters because of this video
I love mine, it’s so gentle and civilized.
I wish they made a modern version with the adjustable slice width thing, it’d be perfect.
It’s Technology Connections.
It’s always worth it. Because

His video on the wok induction heater had so much sass
“What was once an impossibility is now a reality”
I’m not even that interested in kitchenware (mostly) and I still enjoyed that video! Just goes to show how great he is. Hehe.
Same person made me appreciate my can opener
We had one of these. It was terrible. Spring force was super weak and slow and there was no lever to manually lift the toast if it got stuck.
The popping sound is a feature, not a bug. How else can you tell if your toast is ready when you’re doing something else when getting ready in the morning?
Scissors. Their value is noticed most when you cannot find them.
You can always use a knife instead.
But not as precise.
Yeah, but in most cases it’s far, far harder.
Vaccines.
That’s hardly low tech, especially not the newer ones.
“Low technology.”
I think of “low tech” as something that you could with some materials and knowledge do yourself out of a garage.
I would not take an improvised vaccine made in someone’s garage. Not until we were in real fucked up post-apocalyptic scenarios.
They just taste so damn good
In concept perhaps, but idk if I would consider vaccines actually low tech, especially mRNA
I mean, the original style of “Here, we kicked this virus’s ass for you, now you know it’s weaknesses” is pretty low-tech.
Ugh, just got vaxxed and I’m on day two of recovery.
Knives.
About as low tech as it gets, even for modern knives that are pretty high tech in how they’re made.
But it’s entirely possible for a person to make a knife with nothing but tools they can make by hand, with no need for anything other than rocks as tools. I’ve done it, and it isn’t like I’m some kind of super genius.
You can make slightly more high tech tools if you want, and make metal knives. The caveat to that is that you have to know how to identify sources for the metal in the first place, unlike stone tools where you can figure it out by banging rocks together until you find some that make sharp edges. But making an oven that can turn out low-grade materials is realistic for a single person to do.
But a knife, in its essence is just an inclined plane done to a very fine degree. Doesn’t get any more low tech than that. Mind you, there’s plenty of complexity involved in all of the basic machines like inclined planes, but that’s more about understanding them than using them or making them.
Knives are mankind’s most important tool. They were among our first tools, and it can be argued that they were our first manufactured tools. And we still use them regularly. Some of us use them every day, multiple times a day.
That’s a lasting technology in every degree of refinement.
You know what always weirds me out:
The knife is a technology. It was invented by a person. And that person was not the same species as us. The knife has been around longer than Homo Sapiens.
I’ve commented on this before, but it reminds me of the mortise and tenon joint. The oldest intact wooden structure on Earth is held together with mortise and tenon joints. The man who built it never wrote his name down, because writing hadn’t been invented yet. He never rode a horse, because animal husbandry hadn’t been invented yet. He used stone tools, because copper smelting hadn’t been invented yet. In the present day, Festool sells a tool to make mortises called the Domino which they still hold a patent on. We’re still actively developing this technology which has been with us slightly longer than civilization has.
Smelting metal (as opposed to just heating already refined metal) is a non-average skillset, though, and knapping is quite hard to master.
Honestly, kind of mind blowing even thinking of them as a technology, they’re so ubiquitous. I use a knife a minimum of 10 times a day, and that’s just in the kitchen, not including opening mail, packages, small medical stuff, and a ton more uses. Holy shit, where would we be without those inclined edges?
Awesome comment to read at 430 in the morning. Thank you
Also knives and woodworking. Blades are what made the great Japanese temples. Lots of sharp steel and a dream. It is amazing what Japanese blacksmiths can do with steel, and the excellent performance they can achieve with them.
