If you're curious about whatever happened to Corfam:
The Wonderful World of Chemistry was actually about all sorts of DuPont products. As smiley actors and actresses sang "The Happy Plastic Family," audience members sat in Antron-Fabrilite chairs on Nylon carpets, watching the performers in front of a Mylar curtain. But Corfam, a new synthetic leather, was the star of the show. Promoted as having the feel and durability of leather, Corfam shoes also were water-repellent and were supposed to never need shining - attributes that inspired DuPont to proclaim that soon 25 percent of America's footwear would be made of Corfam.

After seven years, DuPont told its wonder shoe to take a walk, at a cost of $100 million. .
