Does anybody know of any that I can research? anon70468 March 14, 2010 I'm an engineering student looking for a shear thickening non newtonian fluid (like corn starch) but one that will not dry out like corn starch does. anon70945 March 16, 2010Īre non newtonian fluids able to stop a bullet? anon70570 March 15, 2010 Armor piercing bullets do not fragment and therefore are much harder to stop. If it is a rapidly fragmenting bullet, it may be slowed down. The bullet does not have much surface area when encountered straight on. The bullet is moving so fast that the soldier would need a suit of armor about five feet thick to stop a bullet. Just so you know, non-Newtonian fluids will not stop a bullet. What's the density of cornstarch and water? anon84008 May 13, 2010 Why it is called non-newtonian fluid? anon86256 May 24, 2010 Thanks, Vinoth KG anon97759 July 21, 2010 is mercury a non-newtonian fluid? if not, explain to me. taufiq, university of indonesia anon110116 yesterday So, are there any newtonian fluids in this world? if there are, can you tell me what they are? thanks. RE: Why it is called non-newtonian fluid? The fluids do not follow the laws that Newton discovered about the behavior of fluids, hence "non-newtonian." -The Answer-er RE: Any newtonian fluids in this world? There are absolutely tons of newtonian fluids. Hopefully you haven't attempted to use it in that way. RE: Able to stop a bullet? As far as Mythbusters has done, the answer is no. It is not a polymer, but ratherm an element, and for something to be a non-newtonian fluid it must be a polymer. RE: mercury a non-newtonian fluid? Mercury is a newtonian fluid. I would like to answer tons of peoples' questions. Humans have a Non-newtonian fluid that runs throughout our bodies. Why do non newtonian fluids change their viscosity under stress? anon156036 February 25, no26: Non-newtonian liquid running through our body is blood. I have to do a report on this and I'm as lost as all get out. Does anybody know what these are or where I can find information about them please? anon235065 December 15, 2011Īm I the only one completely lost? I didn't get half of this. When you stir honey, it will become more like a liquid than a solid.Can somebody please inform me of a point which I am struggling with? I get the Newtonian and Non-Newtonian fluids but the question which I am trying to answer on my assignment also refers to ideal solids and ideal fluids. Honey similarly needs prolonged stress to change it’s properties. If you whip cream for long enough it will appear to go from liquid to solid as it becomes whipped cream.Ĥ. Whipping cream acts differently when under a constant and prolonged stress, such as whipping. Ketchup is almost the opposite of oobleck – it become thinner and runnier under impact, that’s why it helps to bang the end of a ketchup bottle when you’re struggling the get some out.ģ.
Custard behaves just like oobleck, in fact if you filled an entire swimming pool with custard, you would be able to walk across it!Ģ. When the stress is removed, the repulsion returns and the slime becomes liquidy again.
Mechanical stress, such as stirring quickly provides energy that overwhelms the repulsive forces, causing the particles of cornflour to temporarily stick together. The particles of cornflour don’t dissolve in the water, they become suspended in the water and repel each other. The slime we’ve made is a particular non-Newtonian fluid called oobleck (yes it’s a funny sounding word – that’s because it is derived from a Dr. Slime isn’t actually a solid or a liquid – it is a non-Newtonian fluid, this is a fluid that changes its properties when a stress or force is applied. The slime should become a consistency that appears to be a liquid but if you hit it or try to stir it quickly it becomes a solid – so which is it? Liquid or Solid? You can also add food colouring and glitter if you want to add some sparkle to your slime. It’s super easy and quick to make – you just need to mix water and cornflour! Start with a little bit of both, if it seems too runny you can add more cornflour and if it becomes a solid then add more water. With Halloween coming up, what better time to make some of your very own slime?
