I'm left thinking Russian electrics are a bit scary!!

Well if you deliberately overload them and possibly even bypass fuses any electrics get scary. Mix in some seriously dodgy DIY wiring and you'll end up with an explosive mix in just about any country. I've seen some seriously ancient and questionnable wiring in Northern Ireland, not so much in England yet, at least not in person. If you have a look over at DIYnot forums (electrics UK) you'll find a few hot messes rather quickly.
I'm not all that familiar with Russia but the house in the video definitely feels like extreme rural poverty to me and a setting like that usually breeds the worst wiring (and other building details). They do mention that there are no neighbours so I guess this is pretty remote.

I just checked out the video via the above link. All I can say is "MAD". Didn't see any science.

BTW, over on this side of the pond, I occasionally come upon the 1/2" or 3/4" copper pipe in fused disconnects for HVAC units. I posted a few pics over the years here.

Typical ways of bypassing Diazed fuses are wire (individual strands) wrapped around the ceramic body or a nail driven through the metal end caps and ceramic body. The worst kind is usually found in metal shops with a lathe, a solid metal bottle "fuse".
I've been guilty of "repairing" a 20 amp fuse myself, although I knew it only fed a single motor with additional protection of a 25 amp MCB upstream. The MCB was the actual protection for the old motor, the fuse was only necessary to avoid changing the historic wiring (ca.-1920) for a quick test run. Doing that I discovered that a single strand from a 1,5 mm2 conductor probably takes around 16 amps, maybe a bit less - it blew within less than a minute. A second strand fixed that issue. The next time we ran the motor we fitted a proper fuse of course.

Aaah, I think I know what's going on! Looks like a very bad overload, close to a short, and the fuse glows for a brief period of time before it blows (it does, right at the end of the video). The resistive wire is probably the load, not what's inside the fuse! I've been told that these fuses can change as they age and should be replaced every 15 years or something - maybe that's why this one actually starts to glow before it blows?
BTW, the language is Czech. Not that understanding Czech would help much, they don't really talk a lot.

I've seen a few of those guys' videos before and they're absolutely terrifyingly dangerous, including playing around with unshielded magnetrons and so on. As far as I can figure out, they're in the area of Ukraine where the Crimea conflict happened a few years ago. One of their videos is about going to a bloggers' conference in Moscow and you would really feel for them. They're living a rather frugal existence and had to basically hitch hike to Moscow. It's a rather stark look into life in what is basically a very isolated and impoverished place where health and safety rules are the least of their concerns I suspect.
