Styrofoam is a trademark of The Dow Chemical Company for closed-cell extruded polystyrene foam currently made for thermal insulation and craft applications. In 1941, researchers in Dow's Chemical Physics Lab found a way to make foamed polystyrene. Led by Ray McIntire, they "rediscovered" a method first discovered by Swedish inventor Carl Georg Munters.[Dow acquired exclusive rights to use Munters' patents and found ways to make large quantities of extruded polystyrene as a closed cell foam that resists moisture.For more information: wikipedia
Michael Salter has created a life size Formula 1 race car out of styrofoam! If somebody would do the paint job for this eco-F1 racecar replica, this can definitely, be a perfect item for exhibits.
