A unique property of liquids is something called viscosity. Viscosity is a liquid’s resistance to flowing. Viscosity depends on the size and shape of the particles that make the liquid, as well as the attraction between the particles. Liquids that have a LOW viscosity flow quickly (ie. water, rubbing alcohol, and vegetable oil).
Start by filling the jar with 1 cup of water. Add a few drops of food coloring to the water and stir until combined. Pour 1 cup of Oil into the jar. Securely tighten the lid on the jar and shake it for 15-20 seconds. Set the jar down and watch the liquid for a minute or two. Observe what happens to the Oil and the Water.

6 days ago · Oil and Water Exploration. Fill a transparent container with water and drop some cooking oil into it. Observe how the oil forms droplets and floats on the water due to its lower viscosity. Discuss why the oil and water don’t mix. Extend this viscosity experiment with alka seltzer tables. See lava lamp experiment.
Apr 17, 2024 · The viscosity of a fluid is influenced by several factors, such as a substance’s inner molecular structure, shear stress (i.e., mixing the chemical), pressure, and temperature. Although all of these are important variables for determining a liquid’s viscosity, the scope of this lab is to simply focus on the relationship between temperature and viscosity.
Discover and compare the viscosity of different liquids, from oil to water. The viscosity of a liquid is another term for the thickness of a liquid. Thick treacle-like liquids are viscous; runny liquids like water are less viscous. This experiment should take 20 minutes.
Viscosity is a very important quality of liquids that scientists, engineers, and even doctors are frequently trying to measure and change. It is difficult, for example, to transport highly viscous crude oil through offshore pipelines, so scientists and engineers use a variety of methods to try and lower the oil's resistance to flow through the pipelines.

Viscosity is a measurement of a fluid’s resistance to change or deformation, or more simply put, how thick it is. A fluid can be a gas or a liquid, and it is easy to see that liquids are thicker than gases, and therefore have higher viscosities. Of course, some liquids are more viscous than others. For example, honey is more viscous than water.
