Formation of formaldehyde copolymers, nylon rope, high and low density polyethylene, combustion of polyethylene and polystyrene, Beilstein test, formation of solid latex, cleaning oil spills, slime, solid foams, super absorbent polymer, formation of polyurethane foam under normal and micro gravity, and construction of a rod climbing apparatus are demonstrated.
A superabsorbent polymer absorbs many times its weight in water, forming a gel. Sodium chloride disrupts the gel, and the mixture becomes a liquid again.
