The science of cornstarch and water

[@Nathan-wn5mc]

To think I cook with this stuff when I should be using it for a bullet proof vest.

[@rosalieportier]

Ohh good idea

[@rosalieportier]

But it will be heavy tho

[@ridhosamudro2199]

Didn't mythbusters busted it?

[@Chopituppodcastt]

Right? I was thinking about how bad this must be to eat. I seen an episode of strange eaters with a lady addicted to eating corn starch. If you get diarrhea, would it cause constipation? 😂 jk. I'll stick to using Rue for thickening

[@sorou]

so what you're saying is,,, fill local potholes with cornstarch

[@benshore9407]

yea, i'm not too sure about that one, why not just use regular bitumen, much cheaper

[@EliezerEisenberg]

With the advent of EVs, Big Corn knows that the boondoggle of mixing ethanol with gasoline is coming to an end. What better use for the surplus than potholes? Can you spell conspiracy? Who sponsored this study? Inquiring minds want to know.

[@Belioyt]

Actually there is a practical application, if you put a non-newtonian fluid on the road to as a speed bump, a car moving below the speed limit wouldn't experience the bump but a car that is would.

[@voixmin]

There was a company that wanted to make speedbumps with them i think, idk what happened to them...

[@cansmashR]

@@voixmin suicided.

[@mueffe1357]

Didn't someone used this as speedbump? If you go slow, the bump stayed soft. If you drive fast, you become a flying car.

[@roidroid]

yep, they do

[@aoyon_p]

flying cars… the future is now

so this is what they meant long ago when they say "I bet there will be flying cars in the future"

there are prototypes out there using other non-newtonian fluids, corn starch isnt strong enough but there are metallic ones that are more feasible

[@STEAMerBear]

I remember being at a high school party in 1980 and a kid made some of this “oobleck.” I immediately thought of using this stuff as both an armor and a self-healing material. There are so many possible “exotic” materials. We’ve really only begun exploring them. Every solid or liquid element or compound could be explored across a huge range of particle sizes in binary and even poly-material combinations to exploit all kinds of physical and chemical properties. Heterogenous suspension and particularly colloid materials (including foams, gels, sols, emulsions, etc.) are a field with vast unexplored regions. Nature exhibits many material mixtures within such things as snow, bone, blood, milk, lungs, slimes, honeycombs, wood, bark, hyphae and pumice.

[@TheSmokeinator]

how did you go from highschool party to material

[@MrTrollbaby]

whats that got to do with cornstarch? 😬

[@pixelzebra8440]

@MrTrollbaby Hold up what? 😭

[@royksk]

"Yes, but put it away, Matron's coming".

[@Qui-9]

I think it has a lot more to do with things beyond "particle size", because corn starch granule size is not unique to corn starch at all, however, the effect is.

[@paradiselost9946]

theres other types of slime. silly putty aint cornstarch. ive got a tube or two of silicone based stuff. clays admittedly dont do it... but then clay slurry also behaves strangely when something like sodium silicate is added... goes the other way! thins out... holds way more solid material in suspension...all about anions and cations in that case...

[@blazewalter5054]

i wonder if any scientist has tried to shoot a bowl of the stuff

Yes... And it's on KZbin. Kevin from the backyard scientist channel did just that. If I'm not mistaken

Since I learned about non-Newtonian fluids, I started thinking about the possibility of using them as bulletproof material. I'm SO glad the possibility is actually being explored!

[@casi9095]

So cool to make a model! After all conditions vary so being able to track each movement is such an achievement!

[@EliezerEisenberg]

I think the benefit of use in bullet-proofing would be that you could make whole-body armor that would be completely flexible.

[@AtlasReburdened]

Makes me wonder if a non-newtonian fluid has ever been used in a commercially viable linkage between an engine and an automatic transmission. I would call it a torque converter, but I think it would have a different name because the mechanism would be completely different. Maybe just the shape of two interlocking combs but obviously extruded around their rotational axis and with slots milled radially so it looked like an extreme herb grinder.

[@brianb-p6586]

Yes... they're called viscous couplings.

[@trunki006]

0:38 YKW aka Abel van de Ven is such a genious, thank you for being our engineer YKW !

[@user-vn7ce5ig1z]

1:50 - Bulletproof vests huh? That reminds me of shield technology in sci-fi (like in the _Stargate_ series) which exerts a force directly proportional to the amount of force being exerted on it, so that a bullet would be stopped but a knife wouldn't. I wonder if the Goa'uld started out experimenting with a cornstarch-like substance before adapting it to energy. 🤔

[@chadd_robertson]

Ah yes, the science fiction that is: When object A exerts a force on object B, object B will simultaneously exert an oppositely directed force of equal magnitude upon object A... Big ol' Newton number 3. Nah, just kidding, we feel what you're saying my dude👌🏼

What about D3O, the "non-Newtonian" substance used in sports clothing to prevent bone breaks? Downhill skiers, motorcycle racers, volleyball players... also used in cellphone covers. All for absorbing impact energy. With D3O it is said that the impact energy is shunted 90 degrees from its axis.
