Is It Adequate To Oobleck's Viscosity?

Many of things that we interact with are solids and liquids. However, there are some things that are combination of both called a Non-Newtonian Liquid, an example of this is oobleck. This substance has the qualities of a liquid but also has the qualities of a solid when under pressure. One of its qualities as a liquid is its ability to flow, known as viscosity. In this experiment will change the oobleck’s viscosity by changing its thickness. Additionally, applying any pressure to oobleck helps to changes its viscosity. A quick tap on the oobleck cause it to feel hard, this is due to the cornstarch coming together; but slow pressure causes the cornstarch particles to move allowing it to feel similar to water. In this experiment will be using …show more content…
When the ratio of cornstarch to water was regular (2:1), this provided the highest average height of 7 centimeters. This is far greater than that of the thicker (5:2) and the thinner (3:2) oobleck, with the thicker reaching 5.25 centimeters and the thinner reaching 2.25. This is most likely caused by the viscous nature of the oobleck. When the oobleck is too thick, it cannot run enough to reach maximum height. When the oobleck is too thin, it becomes too runny and adhesive to bounce high. Some mistakes made during this lab may have affected this lab negatively. The oobleck may have picked up residue from the previously made oobleck of a differing ratio. The measuring was not completely accurate. The volume of the speaker may have unknowingly changed. Along with mistakes, some problems encountered during this experiment were the lab group’s inability to keep the trash bag taut, troubles with the subwoofer, limited cornstarch, inability to read exact heights, and ineffective ratios. What was learned through the experience of this lab was how the viscosity of a Non-Newtonian Liquid must reach a certain equilibrium to be most effectively
