According to airport security regulations, gels and spreads like jelly are subject to the same carry-on restrictions as liquids. But does jelly count as liquid in the scientific community? The answer is complex, revealing a fascinating overlap between food science, physics, and airport security, with the final classification depending on the context.

According to the National Institutes of Health, bread is a solid, heterogeneous, and unstable foam. This initial definition, however, only scratches the surface of the complex physical state of a piece of bread, which challenges our basic understanding of solids, liquids, and gases.

Interestingly, some medical professionals categorize gummy bears as a 'clear liquid' for pre-procedural diets, but this is a practical classification, not a scientific one based on physical state. To a physicist or chemist, the answer is far more complex than a simple solid or liquid distinction.

From a scientific perspective, ice cream is a complex colloidal system that contains solid, liquid, and gaseous components simultaneously. This fascinating structure is the key to answering the question: is ice cream classed as a fluid? While it behaves like a solid when frozen, its rheological properties reveal a far more complex truth about its nature.

More than 60% of the human body is composed of fluid, but the term 'fluid' applies to much more than just bodily liquids. So, what do fluids include? In physics, a fluid is any substance that continuously deforms and flows under an applied shear stress, and this definition encompasses several states of matter.

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 Yale Scientific Magazine, ice cream contains a fascinating combination of solid, liquid, and gas, which is why the question 'Is ice cream a thickened liquid?' is not as simple as it seems. Unlike a uniformly thick beverage, ice cream is a complex colloidal emulsion with multiple states of matter coexisting simultaneously.

Jell-O is a unique material that confounds our typical understanding of the states of matter. While it jiggles like a solid, its composition is mostly liquid, which traps it in a state known as a colloid. The surprising science behind its form involves a network of protein polymers that hold the liquid in place, creating a semi-rigid structure.

Jelly is a perfect example of a gel, which is a type of colloid consisting of a liquid suspended within a solid network. This unique structure is why jelly doesn't act like a simple liquid or a solid, leading many to question its true state of matter. Understanding if jelly is considered a fluid requires delving into the fascinating field of rheology.
