Little known facts

It’s also the reason why it’s so hard to get it out of the bottle and why smacking the bottle in a certain spot will either get a dollop or get half the bottle :lol:

Actually ketchup is the opposite kind of non-Newtonian liquid: the harder you smack it, the easier it flows.



Corn starch is the kind you describe --



Ketchup is something called a (IIRC) Bingham fluid. It's why the old trick of hitting the side of a ketchup bottle will make it flow. It means you can actually sit a golf ball on top of a bowl of ketchup and it will just sit there (this doesn't work with cheap ketchup because the cheap stuff is mostly water) but if you drop it in from a half meter up it will make a nice splash.

I questioned it, too, and I Googled it before I posted. It is listed as a non-Newtonian fluid. Check it yourself. It all has to do with viscosity.

Meanwhile, the Mythbusters covered it years ago using cornstarch:

 

Everything you’ve ever wanted to know about ketchup, and a bunch of stuff you didn’t.

Go to the 23 minute mark where they explain it being non-Newtonian. These guys do tons of research so I believe what they post.

BTW their podcast has been running over 12 years released a couple times a week. They have very interesting wide ranging topics if anything is interested. Stuff You Should Know, anywhere you get your podcasts.

There are three kinds of non-Newtonian fluid. Ketchup is the kind that loses viscosity where it gets jolted -- it's a "shear-thinning" fluid:

Cornstarch is one of the more familiar type because the difference is so dramatic. Ketchup is down there with latex paint, and I can testify that latex can be truly weird; I've used a paint that if I carefully set the paint brush tip on it the brush just sits there, but if I jab it in it's like sticking a spoon into maple syrup -- there's a little resistance, but not much. With a high quality ketchup you can do something similar; I mentioned the golf ball bit and wish I could find a video of it because it's crazy -- you can carefully sit a golf ball on the surface in a bowl and it just makes a dimple in the surface, but if you drop the golf ball from a foot up it splashes.

They got it right -- ketchup is the opposite of corn starch, it loses viscosity when you impart a force to it.

The term "sharpshooter" had nothing to do with being"sharp": it came from the fact that the Sharpes' rifle was the most accurate long gun of its time, so someone shooting with a Sharps could hit targets at long range that no one else could hit -- literally a "Sharpes' shooter". The term became more generalized partly because top marksmen were given Sharpes' rifles to make them even better, and when the Sharpes was replaced by an even better rifle the tag stuck with the upper-case S getting demoted to lower case -- a sharpshooter. That the word "sharp" suggested accuracy only helped the change along.

"ketchup" is a mispronunciation of a Japanese sauce name.
English speakers call it 'tomato sauce'.

That last depends on the brand. I remember a cheap brand that actually fermented enough that eating a pile of fries with it was enough to light up a breathalyzer -- it was pretty sorry stuff, more suitable for mixing into soil to increase the acidity than for human consumption.
