![]() ![]() ![]() What happens when you warm up honey? With this science activity, families measure and compare the viscosity of different household liquids by doing a simple drop test and measuring how long it takes a marble to pass through each liquid. Viscosity is a property that can be changed, however. When honey is cold, it may be very slow to flow because its viscosity is high-there is more friction within the liquid that is slowing it down. In this week's chemistry-themed family science activity, families explore viscosity, a property of liquids that is a measure of the friction inside the liquid. (If you warm it up, it may flow more quickly!) While it may seem like the quality of the honey you are noticing is its "thickness" or "thinness," another way to talk about what you are seeing is to talk about its viscosity. It is a very important test that offers repeatable and reliable results ensuring that the quality of the product is not only achieved but maintained from batch to batch. Depending on its temperature, it may be especially slow to flow from the bottle. Viscosity testing is a tool used in the production process of just about every type of food and beverage. Have you ever noticed that some liquids are more difficult than others to squeeze from a container? Honey is a great example. ![]()
