"Webbecause of diffusion. Diffusion is the movement of molecules from high concentration to low concentration. Calcium diffuses through the alginate gel layer. When the calcium reaches the inside of the bead, it will cause the alginate there to crosslink and become a gel. This is how the gel shell thickens. After about 5-10 minutes, the bead will be " - Diffusion through a gel and a liquid
