The superglue has been successfully made into beads by mixing the superglue with acid. Producing a shell coating on the beads by adding a base to the acid-superglue mix at which time the outer surface of the bead cures while the inner portion remains as liquid glue. At a too basic pH the entire bead cures, and at a too acidic pH no shell forms. The technology is uses ph to set up a shell of superglue and try to quench the reaction so the center of the bead remains liquid and reactive.
