ABOUT THE SCIENCE
\nThe Physics of Gelation and Density<\/p>\n

    \n
  1. Molecular Dissolution (Sol State):<\/strong> When gelatin powder (made of collagen proteins) is added to hot water, the protein molecules uncoil into random chains and dissolve, forming a viscous liquid solution (a “sol”).<\/span><\/li>\n
  2. Network Formation (Gel State):<\/strong> As the solution cools, the protein chains lose kinetic energy and begin to re-associate. Specific segments of the protein chains refold into their original collagen-like triple-helix structures. These triple helices act as physical cross-links, connecting different protein strands and forming a vast, tangled, three-dimensional network (a “jungle gym” structure) that spans the entire container.<\/span><\/li>\n
  3. Water Entrapment:<\/strong> This protein matrix traps the water molecules within its structure. The water is caught in the mesh and is no longer free to flow as a liquid, although it remains in a liquid state.<\/span><\/li>\n
  4. Increased Density:<\/strong> The resulting gel has a slightly higher density than the hot sol or pure water.<\/span>\n
