Polyurethane Foam Demonstration

Ideal for illustrating foam and polymer production, as well as the use of catalysts in reactions, this dramatic demonstration will cause foam to grow 30 times the original volume of the reactants - a polyether polyol and a polyfunctional isocyanate. Use of a hood with adequate ventilation is recommended for this experiment. Materials included for repeat use.
