I remember that vaccuum cleaner display and standing in front of it trying to "see" the air currents that held that ball in the air. That might have been my earliest consideration that air has volume and weight and fairly constant motion.
As for the candy and nut counter, as I recall it was an island near one of the entries to the store. You'd walk in and ZAP that sweet scent would attack your senses and the visual's became irresistable. The concept was brilliant because today's big box stores smell like a combination of stale popcorn, body odor and cheap floor cleaner. Makes me miss Colombia where the big box stores and even the metro platforms are buffed and shined to perfection.
