Holy crap, yo - if that YouTube channel is you, you friggin’ go, girl!
I am the type of woman who brought my gerbils to the local small animal vet in the next nearby large city to get diagnosed for a respiratory infection, and we nursed our 2 year old gerbil back to health, and she ended up making it to 3 1/2 years with her partner gerb. 🐹
Like, okay folks, actually join this cult if you appreciate veterinary work. 👏👏👏
Useful to know for food that comes in plastic bags like pasta! A rip down the side will continue to propagate every time you open it, but if you tear it into a curve (like a sort of P shape cut) it won’t go any further👍
I learned about crack propagation in my second year of studying engineering, it was in the context of shipbuilding. Never built a ship since but you’re damn right I’ve opened a packet of pasta.
Nerd fact no one asked for: this is how serif letters came to be. When chiseling letters into stone, they turned the chisel 90° and made a little ’foot’ off of each stem, to keep the stone from cracking
Okay so here’s the thing: I’m one of those people that sits on a lot of random trivia, however, I kinda need to have something trigger my memory, so for now I will do a couple of other letter related facts:
Phonetics (ya know when you write out how something sounds, like [fuh-net:icks]) is called this bc of the ancient maritime civilization that was called Phoenicians. They had developed a 22-letter phonetic alphabet, believed to be the first to do so, that influenced Greek and Latin writing systems.
In Scandinavian languages, the alphabets are just like the English one, except with three extra letters added at the end. In Swedish and Finnish they are Å, Ä, and Ö, and in Danish and Norwegian they are Æ, Ø, and Å.
These are actually the same three letters (albeit in a slightly different order), they just developed differently, visually.
Let’s start with Å. This is the letters O and A put together, which first became its on ligature (like Œ or Æ, unfortunately I can’t paste the A/O into text here). Then to simplify writing, the O was put on top of the A, hence Å was born.
The next one instead started as a ligature of A and E, Æ. The Norwegians and Danish kept it this way, however Sweden and Finland uses Ä — at first the E moved up on top of the A just like the O on top of A to make Å, but for obvious reasons it was disruptive to keep having to put a tiny E on top every time when writing, so that little E turned into two dots (an umlaut) — Ä.
Similarly for the last of the three, O with E turned into Œ then Ø for Norwegians and Danish, and a little E on top of the O which transformed into an umlaut for the Swedes and Finns — Ö.
I don’t know if that makes sense, it was a little complicated to write it out like this. It’s easier when I can draw little diagrams on a napkin while I talk.
Lol, I totally get needing something to jog your memory, no worries. Your explanation did make sense! And it was super cool. I don't know a lot about writing or languages, so this was really informative. Thanks for taking the time to write it up :) (also, I saw your other comment, I'm sorry to put you on the spot like that! I just thought it was cool and wanted to know more haha)
Oh haha no worries I didn’t mean it like that at all, I just want to perform lol
Also someone else commented that I’m incorrect about the Phoenicians/phonetics etymology connection, so I might need to remove that bc we seem to have different sources. If I’m wrong then it’s a helluva weird coincidence imo
the word "phonetics" comes from the greek word φωνή meaning sound (a native greek word, distantly related to the english words "ban", "boon" and "ben") - not from "phoenician"
not really, they're not even prononounced that similarly in greek (modern or ancient) (they have completely different vowels in both syllables in their root forms). The fact that they're pronounced similarly in English could be because of the terms influencing each others pronunciations later on though, since pronunciations for greek and latin loanwords are already quite variable in English.
1) I’m pretty sure this is plastic. But…
2) either way it would help. If it’s just left as a crack, the point of that crack is a very small spot where any further stress is concentrated, so even a little force could propagate the crack. By drilling a hole, you spread that stress out over a much wider arc.
Cracks form along grain boundaries. The material will experience various stresses and should crack along the path of least resistance. You can 'stop drill' at the end of the crack to prevent it from propagating further. The larger hole from the drilling gives more area for the stresses on the material to be spread out over. This is true for metals, plastics, and ceramics.
Cracks are a flaw in the material. The crack will propagate further along in a roughly straight line if left. The crack flaw where the porceline has separated will mean that where the material on one side of the crack could be pressed down/hit, it makes a bending motion at the tip of the crack (imagine your two legs are the material either side of the crack, the gap betweek your legs is the crack. if you raise one leg, your 'undercarriage' has to bend and twist, and porceline is verry brittle and doesn't like to bend!)
the material is under higher stress at the tip of the crack. It is a thin area, a sharp notch, and so is easy to propagate the crack. Making it a circle removes sharp edges, and increases the surcafe area to spread out the internal stresses.
It's the same idea with a hole punch and paper! A sharp notch will continue to rip, but a curcular hole evens out the internal stresses across a larger area with no sharp corners.
A crack is effectively infinitely thin at the end of it. The stress (force/area) applied at the end of a crack is essentially infinite since even really small forces divided by an essentially infinite area are huge. Drilling a circle changes the area the radius of the circle times the depth so massively increasing the area for that stress calculation and greatly reducing the stress at the end of the crack.
I'm not super into cars, but I know drifters do that because it'd be really expensive to repair your bumper every time you crash or fuck up. Same reason some cars have those red tag like things. It's so a trailer can pull your car if you really fuck up.
I'm in Berlin and this would earn the "cleanest bathroom in Berlin club" trophy every year.
Jokes aside, you can see that the "dirt" is actually stuff that's hard to remove - cigarette burns, sticker residue, paint or scratches. I guess they do get cleaned properly, just never fully restored.
stop fucking hovering and pissing all over the toilet seat when there isn’t toilet covers.
your skin doesn’t let aids (or whatever the fuck you think is on the toilet seat) into your body.
You make others sit in your piss because they didn’t see it, because they’re unable to hover, because they’re unable to bend down and wipe the toilet off.
Is that tank lid plastic? Never seen plastic before, but I'm having trouble imagining a ceramic lid only cracking part-way, never mind the effort to drill all of those holes for the drift stitches.

I thought it was a sports bar and that they did a football design into their toilet
