Abstract
Polystyrene beads or beads of other thermoplastic material are expanded to a consolidated foam structure in a hollow cavity of a marine float or other structure by providing the beads with a uniform coating of a saturated brine solution or other aqueous solution of water-soluble salt and exposing the solution to microwave energy to boil the solutioln and thereby heat the beads to cause expansion and fusion to a foam structure.
