NFR The absolute best of science ...

Do you twist and split your Oreos and ever wondered why it splits the way it does (if you haven't, you don't think like a scientist)?

On Oreology, the fracture and flow of “milk's favorite cookie®”

The mechanical experience of consumption (i.e., feel, softness, and texture) of many foods is intrinsic to their enjoyable consumption, one example being the ha

Do you dunk (my answer is NO!!!!), if yes, how long:

Physics takes the biscuit - Nature

Why did a light-hearted experiment attract so much attention from the media? The episode is an interesting lesson for those wanting to explain science to the wider public -- equations do not always scare people away.

Let's get off the dam Twitter thread and have some real fun. All opinions welcome.

“While rheology cannot address questions like whether beans belong in chili...”

I don’t split an Oreo open; I just bite it. If I were to split an Oreo, I wouldn’t twist. I would use the two-finger horizontal pressure method, the mechanics of which are apparently far less studied.

I think this needs some extensive study - I am certain overcoming the inertia and adhesive qualities of the cream filling using a two-finger horizontal pressure approach would invariably result in cooky breakage/crumble.

Any physicist in the house? @cody- , how up are you on your rheology?

Used to do it all the time as a kid. Unless the formula has changed considerably, the Oreo wafers’ shear strength far exceeds that of the fluid (cream), provided that two finger pressure is correctly applied in plane with the wafer. Incorrectly applied pressure is likely to result in catastrophic wafer failure.

Never twist. Always dunk.

This is particularly frustrating while one is dunking . . . I 2nd "no twist, always dunk." My Grandkids defy me, however . . .

Ya well there was a real sicko during 3rd period lunch who was doxxing the filling in my buddies cookies.

 

[Old Man]

What happens when the cookie is double stuffed??

 

[troutpocket]

It seems local environmental variables need to be factored in. Sure, in a warm place with high relative humidity the filling may give way quite easily. But on a chilly PNW day I would twist first!

Open your mouth wider!

Oreos are about number three on my list of cookies. I usually forego dunking, twisting or other time wasting motions that get between me and all that sugary goodness, I gobble them all in one bite and get back to fishing.

I'm horrible. Coursework with Newtonian liquids was enough to make me feel like switching majors. I never touched non-Newtonian. Also, I dunk Oreos without splitting them.

You got the cookie apart with your preferred method. Now, how do you eat the two halves? Do you eat the one with the filling first? Do you scrape the filling off with your teeth? Your tongue? What if the filling came apart and some is on both sides?

@_WW_ , you and I just would not get along - growing up in Canada, my favorite cookie was fruit creams (picture below) - I would eat the cookie all around the central fruit, one small bite at a time, then the piece de resistance, the central jam filling went down in one bite - slow and steady - then get back to fishing.

Scrape the cream off with teeth, eat the wafer that had the cream, then the non cream side - only way to do it (except for all the others)!!

I don't dunk, nor do I twist I pull the biscuits straight apart. 90% of the time the creme filling all ends up on one side. I scrape it off with my teeth and eat it, then eat each biscuit individually.

This is the way.

Dunk only, I gave up splitting years ago. When I was young, I vacillated between the twist and slide.

Now for the dunkers, to what depth do you dunk? For how long? Single dunk or double dunk?

I dunk the entire cookie using chopsticks and eat in 1 bite. Approximately 12 second submersion time

Twist, scrape, no dunk. Dunking is for chocolate chip cookies (aka c-cubed)
