Mixing Mastered
Exhibit Type: Hands-on Exhibit
Ages:  All Ages
Location:  Concourse 1 – Concession Side
Presented by:  Physics; Dr. Kun-Ta Wu
Discipline(s):  Engineering, Food, Physics, Science

Mixing is everywhere in our everyday life from baking a birthday cake in the kitchen to making a cup of coffee in the morning. Have you wondered how all these mixings work? What is the best way of performing mixing? From the perspective of physics, mixing is a repeated process of stretching and folding. Think about mixing milk to the coffee. You need a spoon to stir the coffee, but what does stirring really mean? When you stir, you create flows and currents in the fluid, which stretches the fluid. Then, the fluid gets chaotic, which folds the fluid onto itself over and over on a tiny scale. Hence, while you were stirring the coffee to blend it with the milk, what you actually did was to stretch and fold the coffee-milk complex fluid until the fluid is uniform.

In this activity, we will demonstrate the essence of mixing through an activity of blending a couple of colored dough balls. You will learn how blending these balls can be accomplished by simply following the fundamental actions of mixing processes repeatedly.

Are Fluids Soft or Hard?
Exhibit Type: Hands-on Exhibit
Ages:  All Ages
Location:  Concourse 1 – Concession Side
Presented by:  Physics; Dr. Kun-Ta Wu
Discipline(s):  Engineering, Physics, Science, STEM

Liquid is the material state whose shape depends on the container; on the other hand, solid material has a specific shape that resists the external force-induced deformation. Most of the time, we can tell if the material is liquid or solid by examining its response to external force. However, can you think of a material that can be both liquid and solid at the same time depending on how you interact with the material? In this hands-on activity, we will guide you to make a material that is between liquid and solid. When you gently and slowly poke the material, it is fluid like water but when you poke it hard and fast, it is elastic like a solid material. This material is categorized as a non-Newtonian fluid. In this activity, you will learn how non-Newtonian fluid behaves differently from conventional Newtonian fluid.

Physics in Motion
Exhibit Type: Demonstration
Ages:  All Ages
Location:  Concourse 2 – Field Side
Presented by:  Physics; Dr. Rudra Kafle
Discipline(s):  Physics

When objects move in a special environment, their behaviors can be different from what we think. For example, when a magnet moves in a metallic tube, it falls significantly slower than a free fall as if it is defying gravity. We will demonstrate some physical phenomena associated with the objects in motion.
