How MIT Could Help You Pour Ketchup

Posted May 30, 2012 10:53 AM

From CNN.com - Technology:

The video is as short as it is surprising. A hand tilts a glass bottle containing a red glob of ketchup, which -- instead of oozing out in slow motion or getting stuck -- slides out easily, leaving the bottle nearly spotless.

What would this stuff do if you put it on your car windshield? Possibly wipers would not be needed.

I don't se a problem with Ketchup, I don't refrigerate mine, and as a result it runs quite freely, without and big blobs in it, and before anyone says that you have to keep it in the fridge, it has vinegar in it, plus citric acid and sugar, so it can safely be kept on a kitchen shelf for two to four months!!!

A waitress once told me that if you thump it on the '57', the ketchup comes right out. (It works!)

Ketchup is an example of a shear-thinning non-Newtonian fluid. You pop the cap and try to pour, and it doesn't! But! If you shake it a bit, or thump it (I really don't think it matters where) a few times, then it will pour easily.

Welcome to non-Newtonial rheology!
