The ninth annual “What the Fluff?” festival zaps back into Union Square as it honors illustrious Fluff creator, Archibald Query, who concocted the gooey sticky marshmallow spread in Union Square in 1917. On Saturday, September 27, 2014 from 3 p.m.–7 p.m. (raindate Sunday, 9/28) local artists, musicians, theatrical performers, inventors and humorists pay madcap tribute to the creation of this great American foodstuff on two stages. Fluff games and shenanigans spread the sticky goodness throughout the Union Square. Fest-goers can sample the taste of Fluff from local vendors presenting sweet and savory Fluffalicious delights. Pair these with Fluff-inspired cocktails and Fluff-local beer concoctions at nearby watering holes.
