leaving engineering youtube videos on as background noise is great training for when i have a kid and need to constantly filter what they're saying in the next room for signs of impending doom. like this one guy made a "water" gun that freezes the water into ice bullets and then shoots it hard enough to shatter glass, as one does, and he's saying something about an air compressor before offhandedly mentioning a PVC pipe which instantly gets my attention

PVC pipes are not rated for air pressure. if you overpressurize a PVC pipe, it will explode into shrapnel that is almost impossible to remove because it doesn't show up on xrays. this man has made a pipe bomb and is testing it directly next to himself with no safety equipment.

thankfully it fails by the O-ring popping out instead of the pipe fucking exploding. hopefully he learned a valuable less- hey wait what are you doing with that dremel no no NO NO

AHHHHHHHH HE FUCKING RESEATS THE O-RING AND REPRESSURIZES THE PIPE BOMB AND THEN JUST LEAVES IT SITTING THERE

Okay but it's super interesting how

Din = Power = Ganondorf

Naryu = Wisdom = Zelda

Farore = Courage = Link.

Because Din, in the hylian creation myth, created the physical world. Naryu then created the laws - gravity, time, etc. And Farore finally created life - plants and people.

Din created the body, naryu the mind, Farore the soul.

And the triforce and its wielders so perfectly reflect that.

Ganon is physical power, he is big and intimidating and he breaks things. He is cunning and determined, but that's not what he focuses on. He is might makes right.

Zelda is wisdom and cleverness. She is stall tactics and information and team work. She is a powerful mage with a spine of steel, but that's not how she'll win. She is the pen being mightier than the sword.

Link is courage and persistence. He is the wild card sneaking behind enemy ranks, always moving, plunging into terrifying situations head first. He's a phenomenal fighter with a keen wit, but that's not what will get him through his challenges. He is bravery not being the absence of fear but the triumph over it.

They sit in perfect parallels to each other.

And ganon is reborn through his body - his resurrection is immortality. No matter how low he is cast, as long as he has a body he can claw his way back. He can cling to his power, build it ever higher.

Zelda is reborn through the magic of her bloodline. It's the accumulated knowledge handed down for generations, the unique power she must master, the skills she must develop to survive and get her kingdom out the other side intact. Even her name, the knowledge of herself, is handed down from all the way from the very first. Her ancestors knowledge of her future presence, her stability, is what gives her the edge.

Link is reborn in spirit. He is not bound by flesh or blood. Just like his wanderlust soul he can reappear in any time or place. His variation, his unpredictability, is exactly how he fights. It's what makes him so hard to pin down.

Ganons need to build strength means he can't chase after link. Links impulsiveness means zelda can outwit him. Zeldas stationary predictability means she's an easy target for ganon.

But the other direction?

Fire melts ice, ice redirects lightning, lightning burns fire.

And that's the very essence of the triforce.

I genuinely have no clue how someone can think "getting hit on the ear doesn't hurt"

Getting hit ANYWHERE on the head fucking hurts. I've got plenty of experience with it (various sources) for me personally, top of the head hurts worst (I have a gnarly scar there from a dog bite, very sensitive), but ear is pretty high on the list. Bonus Points for how the sensation made my tinnitus act up

The head is like a thin layer of watermelon rhine wrapped around the most precious organ in your body, and to discourage you from bashing it open, it was wrapped in meat that screams when it gets too close to a dangerous object.

I'm also having a hard time understanding how a person can come to that conclusion. It's... it's right there. You can touch and pull and smack your own ear. You will feel it hurt more than most other parts of your body.

I can only conclude that the anon has never had their ear physically abused, and quite frankly, I hope they never do. I hope they know their lack of personal experience is enviable.

How many worms on strings must it take to fill a trench coat so they are able to buy a movie ticket?

spectacular question.

first we need to know the average volume of a standard worm. keeping in mind that a worm is generally less than a gram in weight, that volume could be really small if you sincerely compressed it—so for these measurements, we are assuming that none of our worms in the trench coat are compressed. we're not packing them in there like straw, they're all standing on each other's heads to puppet the trench coat.

assuming this, then, i divided up a single worm into eight segments that could each be approximated to be about the shape of a uniform cylinder, calculated the volume of each of those cylinders, and then added the total volume up. in all, our uncompressed worm came out to about 38.27 cm^3. diagram below:

(a string was used to take the circumference at the midpoint of each segment, and these were then used to calculate the diameter of each segment for the volume calculation.)

okay. we're going to say that the worms are occupying your average adult male-fit trench coat. they would be looking to fill about 80kg worth of space there, 80,000 cm^3. (1 kg = 1,000 cm^3 at human body density). but we need to subtract the legs, because they are most certainly going to have the trench coat drag on the ground. so:

one total leg would come out to about 13.488 kg of your body. double that, and we are subtracting 26.976 kg from our estimated weight. they also would not fill out the hands, so we're taking off a tiny bit more in the form of 1.04 kg. we're leaving the head in the calculation, because i presume they will be filling out an inconspicuous hat too.

put together, this gives us a volume of about 51,984 cm^3, or a final answer of 1,358.35 worms to fill a trench coat!

this also means that you're able to calculate how many worms you are total so long as you know how many kg you are. take your weight in kg, convert it to cm^3 by multiplying it by 1,000, and then divide that number by 38.27. all together, i am approximately 1,306.50 worms large.

ah yes, science communication

[resuswhore]

hot resus imagines.

straddling someone's hips, placing both my palms on either side of their sternum, my hands wrapped around their rib, and doing compressions that way.

similar position, but straying your palms just a bit to the left, compressing directly over the heart.

placing your resusee on their stomach, compressing just over the center of their back, pushing forwards a bit, especially on a drowning victim, getting that fluid out of their lungs.

giving the heimlich to a drowning victim, spraying frothy spittle from their mouth as you force it from their lungs.

belly compressions, having to give a compression and then immediately clear their airway, shoving fingers into their limp mouth.

mouth to mouth from the straddling position, your whole body pressed to theirs.

giving mouth to mouth while they lay against your chest, their head on your shoulder.

so fucking hot.

It’s so scary when ur chronic illnesses have been stable and ur baseline has been decent for a long time only for a flare to hit you and make you close to bedridden. Very humbling
