How life-size cows made of butter became an iconic symbol of the Midwest

> Because the butter used for the Iowa State Fair's cow sculpture is recycled for many years, the cooler where it's made has a funky smell that most fairgoers would never know about on the other side of the display glass.
Freak_NL•5mo ago
The fact that they recycle the butter for about a decade is reassuring though. A full cow worth of butter yearly just sounds wasteful, but this approach scales that back to a tenth of a cow.
grues-dinner•5mo ago
One cow is not so bad in comparison to the erstwhile EU butter mountain: https://en.wikipedia.org/wiki/Butter_mountain

Or the US cheese caverns: https://modernfarmer.com/2022/05/cheese-caves-missouri/, which also, as of 2022, contain about an Ford-class aircraft carrier and a half of butter.

maxerickson•5mo ago
It's 600 pounds of butter. US per capita consumption is about 6.5 pounds per year.

The definition of caring about it because you can see it.

grues-dinner•5mo ago
Say $5/lb (retail price, surely they don't pay this): $3000 for 600lb.

Using cost as a proxy for the intrinsic value of things, I think just the glass in a cow-sized display case will be more than that, let alone with a refrigeration system built into it.

And if we want to go further, think of the embedded costs of the building it's in, and then include staffing, energy, maintenance, etc that's being "burned" by this exhibit!

bombcar•5mo ago
I’m honestly surprised they reuse it. The amounts of butter you see on even a smaller dairy farm is tremendous.
recursive•5mo ago
Probably a PR thing because concerned citizens keep asking about it.
recallingmemory•5mo ago
That is.. pretty gross.

Half of your HN comment history is about veganism.

Aren't there more appropriate places to rant about this subject

Intelligent Extraterrestrial Being: "So get this: I swung by that planet next to Sol, right? And the Bipedalians apparently like enslave a ton of bovine en masse and take up most of their land to feed them, right? And they breed and eat their body fluids and muscles or whatever. Okay, but then I saw they like took the body fluids they nurture their offspring with—the bovine's fluid for the bovine's offspring not their own—, fed it to a bunch of smaller creatures until it became semi-firm, and then molded the hardened fluids into a scale replica of the bovine's likeness and put it in a transparent sarcophagus. I'm serious, it's wild. It's been there for years and people put on a big festival around it..."

"They're made out of meat"

SideburnsOfDoom•5mo ago
Is the whole mass supported on slender legs made of butter, or is there a metal "skeleton" encased in it?
nylonstrung•5mo ago
It contains an armature made of wire
c22•5mo ago
> Sarah has taken great pride in continuing Lyon’s legacy. She’s carved the cow so many times that she can almost sculpt from muscle memory. She starts with an armature, the wire frame that holds it in place, and then slowly shapes 600 pounds of Iowa butter into a 5½-foot-high and 8-foot-long cow over the course of a few days.
grues-dinner•5mo ago
> When twins Hannah and Grace Pratt moved out of their tiny dorm room at the University of Northern Iowa and into their “adult” apartment, the mini-fridge they no longer needed gave their mother, Sarah, an opportunity: an extra place to store her art.

Is there a name for this kind of narrative "cold open" where you plonk a tangential detail of the article in the first paragraph, and only start the article properly in the next one?

My teacher would have crossed it out with "irrelevant, get to the point" in the margin! The irony of this being off the main topic of the article is not lost on me, but I'll drag it back into HN territory by saying "something something AI training data".

bombcar•5mo ago
There’s a journalism school somewhere teaching these “writing tricks” and I hate it with a passion.

The other one is the “hot start” with a paragraph that is interesting and then it suddenly diverts to pages of useless backstory you don’t care about, and doesn’t resume for ages.

privatelypublic•5mo ago
When did it become "hot start" instead of "in medias?"
KnuthIsGod•5mo ago
Disgusting and cruel.
ninju•5mo ago
Disgusting I could see but "cruel" I don't understand...its not like it is a real cow encased in butter.
exolymph•5mo ago
Dairy farming is pretty brutal to the cows, as is all industrial-scale animal husbandry.

(I'm not vegan, I eat dairy. It is what it is.)
