The science of cornstarch and water

The Massachusetts Institute of Technology is an independent, coeducational, privately endowed university in Cambridge, Massachusetts. Our mission is to advance knowledge; to educate students in science, engineering, technology, humanities and social sciences; and to tackle the most pressing problems facing the world today. We are a community of hands-on problem-solvers in love with fundamental science and eager to make the world a better place.

The MIT YouTube channel features videos about all types of MIT research, including the robot cheetah, LIGO, gravitational waves, mathematics, and bombardier beetles, as well as videos on origami, time capsules, and other aspects of life and culture on the MIT campus. Our goal is to open the doors of MIT and bring the Institute to the world through video.

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

[sorou]

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

[nikhileshk]

I would like to see the testing of a bullet proof vest made of corn starch

[mueffe]

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

[dendikurniawan]

scientists: hey cornstarch, are you liquid or solid?

cornstarch: yesn't.

[AakashKalaria]

As a 3D artist, I can see how this research will come down the line in a few years in Fluid Simulation software.

Just got clickbaited so hard, came for a satisfying video but left with knowledge.

Low key pissed that the artsy thumbnail was in no way shape or form apart of the video. Shame shame shame

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.

Scientists: Lets design a new bulletproof vest




*made with cornstarch*

[blazewalter]

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

[SmolHeroine]

29 years later and I'm still playing with it.

[bryandelahoz]

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!

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.

[adityashukla]

It reminds me of one of the episode of TBBT, where they play with starch over a sound system.

First day after no nut november

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.
