COMPLICATED IS MORE REFRESHING

The watered-down (pun intended) version of this would have been them putting speakers on a water fountain, hiding in a van, and talking to people through a mic. This execution is way more interesting since the technology makes it possible for everyone to experience it, rather than a few during a one-day stunt for a case study video. 

Lesson here is to always push the usual solution — even if it means inventing something new.
