KANSAS CITY, Mo. — Gathered for a free music festival, a crowd waits to see one of the headline attractions — an exhibit about fast-food ingredients.
On display: Beakers of powders and liquids that purportedly go into what is clearly meant to look like a McDonald’s burger. Just below are leaves and spices that Chipotle says make up its burrito. As pop bands perform nearby, other festivalgoers play an online game fighting a “galactic battle against artificial ingredients.”
