The DuPont "Wonder World of chemistry"

Symbolizing chemistry, the 100-foot multi-colored Research Tower of the DuPont building challenges other fair structures in spectacular appeal. It is surrounded by a steel shell 70-feet high symbolical of walk ways in chemical plants. In the Hall of Chemistry are shown the orderly process of research and laboratory controlled manufacturing by which DuPont makes its products. A five-stage marionette show reveals how millions products provide better things for better living ... through chemistry.
