* Alcoseal 3-6 LT fire-fighting foam
* thixotropic paint
* fire hose polymer water additives for high flow
To find compounds that are non-Newtonian fluids apart from oobleck, you can follow the following steps:
1. Understand what non-Newtonian fluids are: Non-Newtonian fluids are fluids that do not follow Newton's law of viscosity, which states that the shear stress on a fluid is directly proportional to the rate of strain or deformation. In other words, their viscosity can change depending on the applied stress or strain.
2. Research common non-Newtonian fluids: Several compounds exhibit non-Newtonian behavior. Here are a few examples:
- Cornstarch paste: Similar to oobleck, a mixture of cornstarch and water forms a non-Newtonian fluid when the ratio of cornstarch to water is adjusted.
- Toothpaste: Toothpaste is a pseudo-plastic non-Newtonian fluid that flows more readily when stress is applied.
- Ketchup: Ketchup is also a pseudo-plastic fluid that has higher viscosity under normal conditions, but it becomes less viscous when subjected to shear stress.
- Silly Putty: Silly Putty is an example of a viscoelastic non-Newtonian fluid, meaning it can exhibit both solid-like and liquid-like properties depending on the force applied to it.
- Blood: Blood is a complex non-Newtonian fluid that exhibits properties of both Newtonian and non-Newtonian behavior.
Remember that there are many more examples of non-Newtonian fluids, and their behavior can vary depending on factors such as temperature, pressure, and composition.
