Cornstarch Monster - Non-Newtonian Fluid on Speaker Cone

Cornstarch Monster, also known as "ooblech", is a non-Newtonian fluid. That means it sometimes exhibits the properties of a liquid and sometimes a solid. When it is placed in the cone of a speaker and repetitive audio is played, it comes alive!

@ZXAnimal What kind of grammar snob uses an abbreviation like FFS?

[HarfordHackerspace]

@ZXAnimal Well, I wasn't going to mention all of the errors in your replies, but sentences end with periods, "isn't" has an apostrophe in it and sentences start with capital letters. Addicting is the informal form of the adjective addictive, according to the Oxford Dictionary, anyway. The American Heritage Stedman's Medical Dictionary lists addicting as a verb. The American Heritage Dictionary of the English Language lists addicting as a transitive verb. Slang, like it or not, are still words.

(1/2) In reference to the argument between @reksub10 & @HarfordHackerspace: It would pour LIKE a liquid - if you've ever mixed cornstarch and water, a mixture with too much water is similar in thickness to milk, and a mixture with too much cornstarch is just powdery. The "blob" forms and bounces on the speaker cone because of the vibrations. Ever seen water in a cup ripple when the table it's sitting on is bumped? Similar concept...

[ToxicLovely]

(2/2) A combination of the shape of the cone and the changing, rhythmic, vibrations of the speaker (producing the sound), that cause the molecules in the gel-like cornstarch/water mixture to also vibrate and move in the way you are seeing. Did someone sleep through 7th grade science class?

How did you generate the frequency?

[lilchingstah]

Omg! It's a dog bouncen' around!!! XD

[cirusMEDIA]

Try 5HZ ...i think it morphs into a fetus!!!

@HarfordHackerspace whats somthing looking like antother thing got to do with sexual orientation? or someones distatse of someones sexual orentation,more to the point? is that you mistaking things again ....p.s. im only joking around i actually like your vids ,could you do a ferrel fluid vid on a small budget?

[HarfordHackerspace]

@HarfordHackerspace And I never referred to it as a liquid in any of my comments nor in the video. "Like a liquid" and "resembling a liquid" doesn't mean I called it a liquid. The only person who has called it a liquid is you. I referred to it as a fluid, which it is: it fills the shape of any container that it is held in.

[HarfordHackerspace]

@reksub10 And a homophobe, too? This guy is AWESOME! I'm having a wonderful time! Derp.

[HarfordHackerspace]

@reksub10 And the title of the video is 'FLUID', not 'LIQUID'

[HarfordHackerspace]

@reksub10 If you needed to describe, say, gravy, would you say it is a liquid? Of course. Technically you could call is a suspension as well. We're not describing it as a pure, molecular liquid (like water). So, by your own definition, mixing any two items of different states means they can no longer be described as any state: gas, liquid or solid? Better roll your Mom's pennies for some corn starch and a science textbook.

[reksub10]

@HarfordHackerspace but corn starch and water are 2 seperate things that youve combined and then subjected it to vibration ..caorn starch being a solid and water being the liquid ,so how can it not be any of those if that is what its nade from ,,it dosent matter what it appears to be it matter what it is...so you can have the foot sandwhich all to your self ..in fact half it and you can take the other half when i school your next comment

[HarfordHackerspace]

@reksub10 Buy yourself some cornstarch and water (cornstarch costs less than $1 and water is practically free.) Give it a try before having the foot sandwich.

[HarfordHackerspace]

@reksub10 We did not make it wrong. We tried different ratios of cornstarch and water, one being much too thin. And it does pour exactly like a liquid when not being agitated by the speaker. Water is a liquid, of course. When comparing the physical states of substances, you much do so when they are at the same temperature. Show me some room temperature ice and I'll be quiet. Please read a science book or two before coming on Youtube and making yourself look like a fool.....again.

@HarfordHackerspace cos you made it wrong ,you said it your self ..and if your talking about the stuff that is making form i doubt it pours LIKE a liquid .....so what is water then ,it can exist in the 3 states without changes from H2O

[HarfordHackerspace]

@reksub10 If it is a solid, why can I pour it like a liquid?

[reksub10]

@HarfordHackerspace but it clearly is a solid

[HarfordHackerspace]

@reksub10 Newton did much more work than his description of gravity. This is in reference to the fact that it doesn't exactly fit into the one of the three basic states of matter (solid, liquid, gas...)

[paddoww]

Staring: B-Boy Corny Starch...

[reksub10]

is non-newtonian fluid not a misnomer as it clearly acts totaly in accordace to gravity ,or is the reference to newton from his other work?

[reksub10]

@syntax128 playing justin bieber through the speaker will proavrly give you that shape lol
