It is fcking excellent. I make it in school every year. It serves no purpose other than to make kids look like WTF!!! I think it's similar principle to quicksand?
You a teacher?
 
This fake planet is not real science. Can we get back to planet 9 and the odds of finding it

That and non newtonian substances

Did you say Planet 9 or Plan 9 from Outer Space? Can we discuss Plan 9 from Outer Space please?

Also, what exactly is "the beast with two backs"? I mean, I can guess, but thought I'd make sure.
 
What has science ever achieved ?? It's the biggest load of bullshit. The world needs to wake up to reality and the fact that science is a human fantasy that proves or determines nothing.

The PC and/or tablet/smartphone you made that post on for a start <laugh>
 
You were joking though right?.................
I wont sleep till you answer.
 
Oobleck - if you haven't made this I strongly suggest you give it a go, especially if you have kids.

A non-newton material which means when you apply pressure it turns into a solid state, but releasing pressure turns it into a liquid. However it is neither one nor the other. Very surreal object. Smear it over your partner while making the beast with two backs. You won't regret it.

All you need is Cornstarch and water. NO NOT CORNFLOUR. Cornstarch can be found in any good chinese store.

That's my science contribution. More fun than anything Sisu will post as well :bandit:

I've made it just fine with cornflour before. According to wiki they're the same thing. Maybe you've tried a crap brand?

Walking on custard.......

Let's try the stuff I make. It's just walking on a cornflour water mix with yellow colour added.

The vanilla pod wouldn't allow it in custard

Planet nine, it's a matter of time I think, there are effects on KB objects that have been detected and that is how we found most of the outer lying planets. I think it's a case if where is it rather than does it exist. Accretion theory doesn't fit such large outlying planets at all which has certainly caused a lot of doubt, until exo planets started to be found.

I think they are called Non Newtonian fluids only because solely because they cannot be calculated as a constant by the equations used like most other liquids. The mathematics cannot describe them in the same way.

But does that mean the equations are incomplete or, these fluids are not fluids but solids suspended in liquids. The difference is time, Newtonian fluids are independent of time, where as a non NF has time as a metric on top of the actual physical interactions.

NFs have a viscosity constant coefficient. NNFs do not. they have what appears to be called a time dependent coefficient, as in the rate of which interactions occur with an object and the liquid have a bearing (that would say momentum energy or kinetic energy plays a part too). As in if you stand on custard, you will sink but if you walk you will not, so imo kinetic energy applied to these fluids creates an effect of equal resistance, the increase of pressure over a certain small time period is essential to creating the resistance, ie the applied pressure of your weight with momentum creates enough force to hold your weight for a time/

So are they strange or, is the mathematics incomplete? It's a calculation problem after all when you boil it down and nothing weird about the fluid.

Blood is apparently an NNF. So it does appear to be dependent the type of solids suspended in liquid

There's a orbital plane to look at so its a question of looking there and seeing.... we will see.

I think the second for NNF. they don't compress or move the same way due to the solid particles in the suspension. when compressed thay go rock hard for a second. if you simply stand there they have times to flow out and not go rock hard.

Yeah I know that, it's why I am wondering. Salt solutions are also NNFs, so is blood. Full of dissolved solids and that is the key here imo.
Other liquids have dissolved solids but nowhere near the ppm of NNFs, like sea water.

Add enough salt to the oceans and they will become NNFs

In fact, hitting sea water hurts a lot more than hitting fresh water, from a fall say.
Density must play a part or TDS (total dissolved solids) something I dealt with in marine fish keeping
 
Case in point, custard will only react that way if you add enough powder, ie dissolve far more solids into a liquid or you need to increase incremental force applied over a wider area, as in a less thick custard requires you to stomp harder and wear flippers to widen the area you apply pressure to.

TDS appears essential to this effect. Simply, you need to bunch enough dissolved solids together and this is done by applying force to an area faster than the fluid can flow. It's not even weird, it makes perfect sense

So NNFs might just be in someone's mathematical dream, just because Newtonian mathematics cannot quantify it as other fluids are calculated.


Glass is a fluid btw,

You made what.. Cornstarch creates a semitransparent thick goop, Cornflower makes a white sticky goop that has starch in it, and corn.that is not the same at all .<laugh> Cornstarch comes from the plant, starch in corn is from turning it into cornflower, fermentation and sugars and some **** like that
