In many clinical and dietary contexts, chocolate pudding is officially counted as a fluid because it is a liquid at room temperature. This might seem surprising given its thick consistency, revealing a fascinating distinction between the scientific definition of a fluid and its practical application.

According to the Canadian Air Transport Security Authority (CATSA), yogurt is considered a non-solid food and must be in containers of 100 ml or less for carry-on baggage. This raises the intriguing question: is yogurt classed as liquid by scientific or culinary standards as well?

Though most people think of yogurt as a semi-solid food, it is scientifically characterized as a colloid, specifically a gel. This means yogurt is a complex mixture of solid particles dispersed within a liquid medium, a property that makes it both solid-like and liquid-like simultaneously.

From a basic perspective, milk is a liquid, but this simple description hides its true complexity. In reality, milk is a complex colloidal dispersion, meaning it contains components that exist in solid and liquid phases mixed together. This multifaceted nature is why the question 'is milk a fluid or solid?' doesn't have a simple, one-word answer.

Custard is a classic culinary creation, but its behavior is anything but ordinary. Unlike water, which has a constant viscosity, custard is a non-Newtonian fluid, meaning its viscosity changes depending on the force applied to it. This unusual property makes it a captivating subject for both home cooks and fluid dynamics enthusiasts alike.

According to the Codex Alimentarius, a collection of internationally recognized standards, yogurt is defined as a coagulated milk product resulting from the fermentation of milk by two specific starter cultures: *Lactobacillus delbrueckii subsp. bulgaricus* and *Streptococcus thermophilus*. This definition highlights the critical microbial action that distinguishes yogurt from other cultured dairy products.

Did you know that while all liquids are considered fluids, the reverse is not always true? The question, is milk a liquid or fluid, reveals fascinating insights into the unique physical and chemical makeup of this common beverage and the precise definitions used in science.

According to the principles of fluid dynamics, milkshakes are indeed a type of fluid, but their unique properties set them apart from simple liquids like water. Understanding the science behind your favorite treat reveals a fascinating world of rheology and complex mixtures.

According to food scientists, the creamy, smooth yogurt you enjoy is a complex substance, technically classified as a colloid and a non-Newtonian fluid. This means the question, "Is yogurt technically a liquid?" doesn't have a simple yes or no answer, challenging our everyday understanding of solids and liquids and revealing insights for a comprehensive nutrition diet.

According to a 2023 statement from the TSA, peanut butter is officially classified as a liquid for air travel, a ruling that sparked widespread confusion and debate. So, does peanut butter count as liquid? The definitive answer depends entirely on the context and perspective you are applying.
