Honey

Definition

Honey is a sweet, viscous substance produced by bees from the nectar of flowers, primarily composed of sugars like fructose and glucose. In the context of mechanical properties of biological materials, honey serves as a fascinating example due to its unique viscoelastic behavior, which allows it to absorb energy and deform under stress, making it a potential model for designing biomimetic materials that mimic these properties.
