An average glass of cow's milk is composed of around 87% water, but the remaining 13% of its content is a highly complex combination of fats, proteins, carbohydrates, vitamins, and minerals. This makes milk a complex mixture, a fascinating subject for both food science and chemistry.

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.
