Mine is this little tidbit about Khaki’s from https://www.heddels.com/2019/05/history-khaki-anything-drab/
“Tried and tested by all the major powers, khaki-dyed, lightweight cotton twills became the de facto uniform for any colonizing power. If you were going to ship your boys abroad to pillage and conquer someplace in the Southern Hemisphere, khaki was your go-to color.”
How pineapples grow amazes me. Ofc if you’re from a place where pineapples grow, it probably sounds dumb, but I learnt that late in my life. Look:
Those fake astroturf fields and yards people are installing are actually quite toxic. In addition to heating plastic to high temperatures and baking it under powerful UV light each summer, the plastics and rubbers used for them are usually from sources like car tires which are full of PFAS to resist fires, wear, UV, etc. Those leach into surrounding areas whenever it rains.
Well that’s fucking awful, thank you!
“Blue lights on train platforms in Japan have been shown to reduce the chance someone will jump in front of a speeding train. In fact, one study in the Journal of Affective Disorders found blue lighting reduced suicide attempts by 84%. It’s believed blue registers as a calming color, associated with the sky and sea, which may be soothing to people in distress, according to Psychology Today.”
I guess people who keep using blue-light filter glasses at end of work will miss this.
Lol dark thought at the end
Not really a secret, but we don’t often think about it.
Cash is fucking dirty. Here is the official Fedral Reserve estimated lifespan for each note:
Denomination Estimated Lifespan* $1 7.2 years $5 5.8 years $10 5.7 years $20 11.1 years $50 14.9 years $100 24.0 years You can assume that something like a $5 bill might change hands on a weekly basis.
So if you a $5 bill that still looks nice, it might be only 2 years old, so it might have seen about 100 owners up until now. It is said that 1 out of 5 people don’t wash hands after pooping.
Your $5 bill is probably filled with poop, pee, sweat, food, cum, dirt, etc.
Cocaine. Lots of cocaine.
Man, cash don’t have owners. Only spenders.
Your $5 bill is probably filled with poop, pee, sweat, food, cum, dirt, etc.
So you’re saying extra protein when I use it to shove things in my nose.
so the blow wasn’ t the problem I just needed a safer instrument
Some antique toasters gracefully lifted your toast, perfectly browned, rather than popping them up like it’s trying to give you a heart attack.
I too dream of the sunbeam radiant toaster.
Ever since I saw Adam Savage showing one off I have craved the majesty with maybe one or two extra safety measures modded in.
I have one from the 50s/60s(?) that will gradually let two slices of toast up, but if you have only one piece of toast and you put it in the wrong slot, it will literally fly out of the toaster.
I had to move the fridge after losing several pieces of toast between it and the counter before I learned what was going on. Was very confused about missing bread and the cat was a prime suspect.

The chainsaw was first used to saw bone, not trees. This was before anesthesia.
The chainsaw was first used to saw bone, not trees
That makes it sound like it was used for amputation…
It was invented to aid with childbirth
HOW IS THAT BETTER
The baby comes out much easier in two pieces.
Whatever, king Solomon.
the next invention was the immersion blender
Oh, it’s for the baby. Okay, got it, carry on then.
The crazy part is it was less painful then what they were doing without the chainsaw…
On the plus side I believe that was the same time they invented vibrators, and when women complained about how shitty everything was, they’d just go get vibrated to cure their “hysteria”.
Here’s a very upbeat song by Riki Lindholm about it:
Chainsaws are fast, imagine doing it with a manual saw
Yeah. Came here to write that. It was meant for the Pubic symphysis amongst others. Well, think about the structures you hit cutting there.
Yes. The structure they forgot to fully put into anatomy books until recently. Amongst others.
In other words: it would cut right through the inner part of the clitoris when used as intended.
oof
It used to be hand-cranked too.
Hadn’t heard the hank crank part before. That’s extra brutal
I’m so happy that I’m living in 2025
In use in Ireland until the 1980s, apparently. TIL.
“Hey while you’re giving birth anyway, I’m just gonna use this hand-cranked kitchen appliance thing to saw your pelvis apart. Please try to relax.”
Today they use this sleek and futuristic implement for episiotomies
Thank God it’s rounded off, this could really have hurt someone.
I’m a dude and that still have me a physical reflex
That’s fuckin’ sweet! I want to attach the crank arm to a bicycle crank, then I can ride thru the forest and nothing can stop me
And it was made for use during childbirth.
The band saw was also created to cut through meat and bone.
The first microwave ovens created were being used to gently re-warm frozen live hamsters, because when they tried to reheat the hamsters with conventional cooking methods, they heated unevenly and burned at the edges, which isn’t good for the hamsters.
Anyone else randomly think of Joe Cartoon for the first time in a very long time?
You ain’t got the balls! No. Balls.
I probably got that wrong, but it’s also been at least 20 years since I last pressed those blender buttons.
I have to assume the microwave didn’t work either, because they cook far more unevenly than an oven.
It was actually rather successful! Some papers about this research are available here (first use of a microwave to thaw living rats) and here (comparison of some other warming methods), and there’s a good Tom Scott video on the experiment as well.
On high, yes. Lower and intermittent power in micro wave heats far more evenly than an oven
Modern ones do have hotspots and cold spots because of resonance and design tradeoffs, but I don’t think that was a problem for the hamster application. IDK, maybe they were structured a little more small and special-purpose, but regardless it was just penetrating radiation basically all throughout the hamster which is better than heating it from the outside in and having the heat having to conduct its way through the frozen tissue.
Basically the same reason you can defrost meat in the microwave, but you can’t throw it in the oven to defrost more quickly without also cooking the edges.
Microwaves also heat from the outside in. The difference is the heat can be turned on and off as easily as a light switch, whereas an oven is literally just a hot box. Defrosting works solely because the heat can be turned off for 14 out of 20 seconds (or what ever cycle the microwave has) to let the heat conduct through the frozen tissue.
I wouldn’t be surprised if the hamster/rat defrosters achieved their results by simply being less powerful than a kitchen appliance.
Microwaves penetrate a certain distance into the material and then turn into heat. Heat conduction from the outside doesn’t. I don’t know exactly what the average of that distance is and how it compares to the size of a hamster, but I would bet that it’s pretty competitive with the thickness of the hamster.
Your whole argument here makes no sense at all. Having the ambient temperature set to the perfect defrosting value would work better than heating the skin of the frozen meat in cycles of full on / full off, if the microwaves were getting stopped right at the skin and then the heat had to conduct in from there.
I merely stated basic facts of how microwaves work. It is only your own shortcomings and assumptions that leave you confused.
But you’re incorrect. Microwaves penetrate through many substances fairly well, mostly passing through them. The microwave ovens we use to cook are tuned to resonate with water molecules, and as a result the waves interact more frequently with those molecules. But in general, the waves just bounce around until they do interact with something, and it could be any particle within your hot pocket that it interacts with, not just the surface.
All that is to say, microwaves do heat all throughout whatever you put in. Now, these waves can also excite particles and moisture in the air within the oven, and there is convection between the air and your hot pocket… But air is less dense than food, so convection will be secondary heating at best, and cooling at worst.
Yeah. They don’t penetrate an unlimited distance into the food, the center of some stuff won’t get heated. But they penetrate a lot further than the 0 distance that ambient heat from the outside does, conducting heat straight to the skin of the food and then letting it work its way in from there.
No idea what this person’s issue is, I sort of suspect that it’s just Lemmy in action, doing its thing.
So are you meaning to imply food, and especially live animals as being discussed here, don’t have significant water content? Because I have bad news for you: If it’s absorbed readily near the surface, it’s not getting much deeper.
Go ahead and try to “defrost” some meat on high. You will see that I am absolutely correct that the OUTSIDE will cook before the inside is defrosted.
Note that nowhere did I say it’s as inefficient as an oven, either, so if you’re imagining that’s what I said then you need to reread my posts. I merely described how the common misconception of microwaves heating things from the inside is incorrect. The outside will basically always heat faster unless it’s completely devoid of moisture, which is not the case what so ever in this context, nor in basically any context of “defrosting”.
No, you’re a shortcoming assumption.
Why do these white hamsters keep turning brown!?
I used to have a really smart hamster. But something… happened… to him.
They were invented because a microwave radar unit melted the chocolate in a guys pocket.
That’s actually one of those Urban legends things. The guy made it intentionally to Cook and it was later refined to had stacks of die punched metal sheets instead of the carefully machined blocks.
Ok what the fuck. Is there a source beyond the youtube video I don’t want to watch right now. That’s pretty wild claim. The few sites I visit seem to reference the YouTube video as the source
Platypus already linked to a paper which references it: https://pmc.ncbi.nlm.nih.gov/articles/PMC1363505/pdf/jphysiol01379-0153.pdf
Hugo Boss (the clothing line) started out making uniforms for the Nazi Party.
You know they are some of the most iconic uniforms of all time I’ll give them that
And yet they did not designed them just used their looms and sewing machines
Anything organic will burn.
Any warning label you have ever seen exists because enough people did the thing being warned against that a lawyer said there needed to be a sign.
My wife recently noticed a new sign by our building’s pool saying that you are not allowed in if you have diarrhea or have had diarrhea in the last 14 days. 🤔🥴
That’s a pretty standard sign in most shared pools tbf. People are gross af.
Gross, and yes. That would be why
Diarrhea and the pool has to be closed and shocked with chlorine for 24 hours… That’s why
More like a law was made to say, “if you’re warned first it’s your own damn fault”.
Hiram Maxim (1840 - 1916) invented the modern mousetrap and the first automatic machine gun.

And the maxim gun is still in use today. Not new ones, mind you, the ones from his lifetime.
I believe that he also invented the first silencers.
During the War on Terror, there was a much-publicized fact that your own household furnishings were much more likely to kill you than terrorist.
And supposedly; You’re more likely to die from a donkey than a plane.
If the donkey’s flying a plane does that increase the chances of you dying?
Artificial raspberry flavor is made from beaver anal glands.
That’s a funny way to spell vanilla.
Which brings us to just one of those bizarre US things, “artificial flavor” versus “natural flavor” is totally arbitrary and random. It’s based on which molecule, not what the source is, so you can have “natural flavors” that came from a massive stainless steel tank and will kill you if you touch them in pure form without the proper protective gear, or “artificial flavors” that come from squeezing beaver ass glands.Edit: Every word of this post is wrong. Literally every one. I think I read a book decades ago that told me this, maybe I remembered it wrong, but anyway according to the internet of today it’s different and I’m a big dummy.
It’s based on which molecule, not what the source is
Other way around. You can have identical molecules be classified as “artificial” or “natural” depending upon whether they were synthesized or extracted.
https://www.reddit.com/r/askscience/comments/svbl7/what_are_artificial_flavors_made_out_of/
Oh, you’re completely right. IDK how I thought it was different, but yes, what I said was completely wrong.
Which brings us to just one of those bizarre US things, “artificial flavor” versus “natural flavor” is totally arbitrary and random. It’s based on which molecule, not what the source is,
But, that’s sensible. If it’s the chemical you find in raspberry, then its natural raspberry flavor. If it’s something we invented or discovered that’s like raspberry, its artificial. Who cares if it came from a bioreactor?
will kill you if you touch them in pure form without the proper protective gear,
While I wouldn’t recommend eating concentrated artificial flavours, touching them won’t kill you. Unless you jump into the reactor, but jumping into one would kill you no matter what the substance inside is.
The gifts from this perfect creatures never cease to amaze me. Thank you kind beaver, your greatness humbles me and all humans.
Their tooth enamel is partly iron which strengthens them and makes them a rusty orange color
Seems unnecessary. Raspberries are plentiful and likely cheaper than beaver parts.
Yeah, it sounds like this might not actually be as common as suggested. Synthetic chemicals are usually going to be cheaper than hunting a beaver.
Makes me wonder why whale puke still gets used in cosmetics…
The synthetics are usually inferior to natural products if you’re going high-end. There’s probably thousands of individual compounds in ambergris. Similarly, I’m guessing if you go for really bougie raspberry flavouring it’s more likely to use castoreum.
I guess that I would have thought that you could isolate those individual compounds, and then reproduce them, rather than hoping that you can find a lucky ball of whale puke.
I dunno, I’m pretty sure I’m not their target audience.
In theory you could, although I’d guess it’d be an incredible amount of work, and might cost more in the end. Most attempts at replicating natural flavours and scents have historically been unconvincing, although some of the recent stuff has been incredible.
I wonder if there’s any food scientists on Lemmy.
Yeah, a little research online says it’s likely only used in perfumes due to expense, but technically it could be used in food.
Most foods though will just use raspberries in some form or another.
