I went to the cheese museum in Gouda last year and they explained that according to the current theory our ancestors discovered butter and cheese by hanging pouches of milk on their horses or cattle while traveling. The movement would turn the milk into butter and, if they used pouches made of animal stomach, the bacteria would turn the milk into cheese. So this is more or less the method by which we discovered butter in the first place.

I was gonna say. The idea of Mongols herding on the planes with a diet that contains a lot of butter suddenly makes a lot more sense. The idea that folks would invent a mode of long-term food storage for free/accident is kind of mind-blowing.
they pour heavy cream and salt into double-bagged Ziplocs and secure the squishy bags of dairy inside their matching running vests
Saved you a click.
:}
This just in. Agitating heavy cream makes butter.
Y'all just discovered something people have known for, like, 5000+ years.
We dug into the science...
The attached image grosses me out.
Alright, from the picture, I assumed they were squeezing cream in their hands during the run and the sweat was involved in the process. I am very happy that is not the case.
Agreed. IMO, having butter all over her hands was the click-bait portion of the post.

tl;dr - they run with zip lock bags of cream and salt and try not to get too warm, but it does all work.
Youse have just found a way to make exercise fattening
America is turning footsteps into butter
Perfect for a little butter on the nips to prevent chaffing.
Great idea. I used to put bandaids on mine.
TIHI
You can make butter while fucking too...
It takes longer than 30 seconds to make butter.
Whelp, I guess I'm never eating these again.
Family Size!
Thanks Nabisco 👍
The average American waistline is now "family sized”
I only make yogurt.
What, no tapioca? No mayonnaise?
Amateur
I remember making butter in kindergarten by putting the cream and salt into a little bottle and just shaking the shit out of it all damn day. By the time we went home, we had about half a stick of butter.
sterile processing tech at a hospital
Not the most confidence-inspiring thing to read after seeing that photo
What an odd wonderful thing to do. I love it
That's probably much less efficient than just using the machine that performs the same process though.
But if you're running anyway...
It's min-maxing. They already commit to the time for exercise so if they could be productive with it somehow why not? "Productive" here more of a 2 seconds of Internet fame than "this has general application", but just like a daily commute being limited mostly to music/podcast/phone calls as far as being "productive", if someone introduced the ability to prep dinner while commuting many people would take them up on it.
It might not be the traditional or most perfect place or time to make "x" but if it buys you time elsewhere and there aren't other consequences or side effectd, well everyone is pretty maxed out in the world and doesn't have time.
Yep, but the machine can also do the work while you're running, or even commuting.
