Inspired by #HamaYourResearch, explore network formation in globular protein hydrogels using Hama beads and grids. We study cluster formation in biomaterials. Our beads are biological molecules called proteins and our grid is liquid water. Our proteins diffuse through water until they meet another protein, after which they stick together via chemical cross-linking. When the proteins are stuck together in a network that spans the 3-dimensions of the liquid, percolation occurs
