i mae that bgefore it is soo cool!!!!! but is smells really bad i love making it!! if they stood there they would get sucked in. put by running on it it dosent give way

Alrighty kids...I think it may be time to stop this useless quarrel about the definition of "non-newtonian" and ask the real question:

What would happen if I peed in that pool"

I know what that stuff is i used to play with it all the time as a kid its just powdered cornstarch and the right amout of water its cool you can try it just keep adding water till it hard when you poke it fast but if you place your finger on it it feels like water

"There are a lot of people here quoting stuff without knowing what they are quoting....

It is not a fluid, it is a solid/liquid suspension" Mani-Jac

We didnt have yet enough of one "know it all dildo" we needed a 2nd one! Please check your sources before saying such BS! Cornstarch + water is a solid-liquid suspension alright, but that does NOT disqualify it as being a fluid. A fluid is something that deforms (flows) when stress is applied. Fluid can be in a any forms of matter (liquid, solid (plastic solids), gas, plasma) or also any combination (suspension/colloid) of those as long as they meet the basic criteria of fluidity. Non-newtonian FLUIDS (you will notice the word fluid is there in evry source you will look at) are still fluids up to the point that the applied stress is so great that they dont move anymore, then they become solids.

Well I was going to point out that water contracts as it cools down and then expands at the point where it actually freezes, which is why ice floats, but other people have as well.

The clip gets a 4.

I was glad to see someone post a link to back up their statements rather than just claiming to know everything there was about the matter and that everyone else is be stupid.

Further searching the Wikipedia has resulted in these little snippets.

A Newtonian fluid is a fluid that flows like water—its shear stress is linearly proportional to the velocity gradient in the direction perpendicular to the plane of shear. The constant of proportionality is known as the viscosity.

A non-Newtonian fluid is a fluid in which the viscosity changes with the applied strain rate. As a result, non-Newtonian fluids may not have a well-defined viscosity.

Oobleck was originally popularized as a fictional form of green precipitation described by Dr. Seuss in Bartholomew and the Oobleck.

The word has since been used to describe a substance that is used as a science aid to teach children about liquids and solids.

same to you. you obviously didnt pass 9th grade science, where they tell you what a Non-Newtonian fluid is.
"goaliejerry water molocules compact to form the solid state of ice, and expand to cause the vapor state of steam dickhead"
no, no they dont. the hydrogen bonds in water cause "holes" inbetween the water molecules (when it freeses), expanding the water... not compacting it.

It`s easy to extricate yourself from a non-Newtonian. . . Just don`t move fast. You could see the fluid drippin off of them. At low energies the viscosity is similar to oil.

Actualy, Ice is less dense than water.
#1. Ice floats on water
#2. fill a bottle to the top with water, toss it in your freezer and wait untill it freezes. you`ll have an exploded bottle.

I live in canada, i do the water/ice thing alot. One of my favorites is freezing a water baloon and going snow bowling.

what these guys dont understand is that to get out, they`ll have to apply stress, so of course its gonna then have properties of a solid, so they`ll get stuck. It`s been done so many times on shows like brainiac and How2

It was on an english program. Called Brainiac and the pool was way biger than this! It was a propper pool so they used loike hundreds of bags full of custard and loads of cement mixing machines.

its called Oobleck.

u need like 2/3 cup flour and 1/2 cup water or something and u mix em and wala u have OOBLECK

A non-Newtonian fluid is a fluid in which the viscosity changes with the applied strain rate. As a result, non-Newtonian fluids may not have a well-defined viscosity.

this is non-newtonian fluid. It is a proper term. Non-newtonian does not mean it doesn`t obey the laws of the "universe". It basically means that its viscosity changes depending on the stress applied to it. as demostrated.

I mean, is water a "classical" fluid? After all, it expands when cooled to a solid state, unlike practically every other liquid possible in reality. What, pray tell, is a "classical" liquid, then, if water doesn`t count?

I mean, oobleck will flow downhill, right? It will conform to its container, right?

Oobleck IS NOT A LIQUID, is what I`m getting at. It is particulate matter suspended in a liquid.

There is no violation of newtonian physics. Calling this simple experiment non-newtonian confuses both the meaning of newtonian and gives the false impression that this is anything more than QUICKSAND using a material finer than sand.

Oh, so I see, then what they mean, TOM, is that non-newtonian means newtonian? If it is non-newtonian, what law of newton is being violated?

I know what they were trying to say. I`m just a stickler for accuracy and validity.

goaliejerry, what they mean by non-Newtonian is that it isn`t a "classical" fluid with all the properties that classical fluids have.

Didn`t I make this stuff in elementary school? We colored it green, and read dr. suess. It was cool then, but kind of lame now.
