May The Force (of Mayonnaise) Be With You!
Roland Piquepaille writes "A team of chemists at Rice University was working last year on two separate projects: trying to create strong fibers from carbon nanotubes, and testing emulsions of oil and water. And they discovered that a force known as 'negative first normal stress difference' was present in both solutions. The next step was to go to a grocery store and buy a more common emulsion, namely a jar of mayonnaise. And bingo! This force was also at work. They tell us more in this news release, "Bizarre Attractive Force Found in Mayonnaise." Unfortunately, they don't know what to do from their findings. Still, it's fun science. More details and references are available in this overview."
No wonder I'm addicted to Mayo! It's that hitherto unknown attractive force that compelled me to eat jar after jar.

I suggest you try putting a jar in the freezer then let it thaw.
There's a whole bunch of other foodstuffs you can test for this phenomenon: peanut butter, egg yolks and/or whites, gravy... hmmmm.. gravy. argl-argl-argl....
click-clack, front and back. I'm not moving this car otherwise.
May be mixture doesn't mean what I think it does.

Oh wait. This is /. so I'll have to cut and paste it...
"Emulsions are combinations of two or more liquids that do not mix, and they are common in industrial settings like oil fields as well as in everyday foodstuffs like mayonnaise or vinaigrette salad dressing. In oil and water, an emulsion is created when tiny droplets of water become dispersed throughout the oil.
Yeah... I can't afford a real bulletproof vest made out of Kevlar, so I'm just going to smear Mayo over myself.
Yeah, like I need an excuse to do that anyway!
My own prize-worthy contribution to human knowledge
will describe the mysterious repulsive force which
can be confirmed to emanate from the accumulation
of emulsion lipids in adipose tissue of the consumer.
I've passed on blind dates for fear of this "dark matter".

...Is there anything it can't do?
So... Strong. Weak. Electromagnetic. Gravity. and um, MAYO?
Yeesh, talk about not being able to see the forest for the trees. Make sandwiches, of course!
Please help metamoderate.
No really!
If you read the article the negative first normal stress difference says that sliding plates across "-- created forces that tugged the plates together. "
Well, when you twist the lid, isn't that what you're doing? (Sliding it relative to the rest of the jar?)

Does this mean that we can build the Space Elevator out of mayonnaise?

Technically, mixtures are just substances put together. Mixtures are normally divided into two categories. Heterogonous mixtures are of varying consistency (like a salad or oil and water). Homogenous mixtures are uniform throughout (like a solution of sugar water). So oil and water can mix, but they just aren't soluble with each other.
Is this an April Fools joke or is it for real?
