Corn starch + water makes “oobleck”, a non-Newtonian fluid.

Most every cook and chef knows that when you are going to use cornstarch in a recipe, usually to thicken a sauce, you dissolve the cornstarch in a cup of COLD water first, stirring slowly. If you use hot water it will clump up..............

Corn starch, water, and juices from a roast make gravy.

As an aside, iron also is strengthened by hammering on it. It’s called forging. Been done for hundreds of years.

Uncanny "Adaptive Durability" Makes This Strange New Material Stronger Every Time You Hit It

Funny, I thought that was the definition of "hammer-forged."

[Red Badger]

True but iron starts out as a very hot liquid, requiring lots of energy input. This stuff is room temperature..........................

“When I stir cornstarch and water slowly, the spoon moves easily,” explains Yue (Jessica) Wang, a materials scientist and the project’s principal investigator. “But if I lift the spoon out and then stab the mixture, the spoon doesn’t go back in. It’s like stabbing a hard surface.”

There was an episode of "Mythbusters" where they filled a tank with a cornstarch and water mixture, and were able to run across the surface.

Forging makes it more fragile, but stronger- when heated, it becomes easier to bend (less strong, or more maleable), but when hammered, it will become more solid, less malleable, but also more apt to break, or snap, instead of bending when stressed.

I used to work with gold, and would pour out melted gold, which was very bendy, and would work it through a roller of,vsriousmsizes and shapes, and after awhile, it became harder to squash to size, and eventually would crack if overworked.

‘gets stronger every time you hit it’

Does Laz know?

“I used to work with gold”

Interesting. Look up “large metal press” in youtube.

Thanks, I will. I loved working with the gold, but the roller I had, cast iron, developed a Crack ar a stress point, and I wasn’t able to accurately roll out the gold anymore- I never got around to buying a new one.

A jeweler friend gave me an old crucible to use for heating the gold, and I was able to dig out enough gold beads that embedded in the divots to make a ring out of. I don’t know what the actual product carat was as the gold I dug out was likely a combo of different carats. Probably ended up being around 16 carat or so.

Another friend had to have a tooth extracted that had white gold in it. He asked if,i could make a ring out of it, which I did.

Had a lot of fun working gold-

How many family members does Wang have in China? How soon will her research arrive on the Mainland?
