What the Fluff?

Union Square • Somerville, MA

So, What’s the Fluff?

Now in its 11th year, “What the Fluff? A Tribute to Union Square Invention” is a madcap festival honoring the invention of Marshmallow Fluff. This fun-filled event draws over 12,000 people and is cited as one of the reasons why Lonely Planet named Somerville in the top 10 “Best In The US” travel destinations for 2016.

Join us for a celebration of the genius of Archibald Query, who invented Fluff right in Union Square in 1917. Artists, musicians, theatrical performers, culinary geniuses and the general public pay tribute to this great American creation in a zany, fun-filled festival. The 11th annual event features musical performances, a cooking contest, fluff-themed games, activities, antics and fun for every age, and Fluff treats of every sort. With this year’s theme of “Fluff U: A Sweet Education”, we’re transforming the beloved Union Square into our very own sticky, sweet campus.

“What the Fluff?” A Tribute to Union Square Invention is presented by Union Square Main Streets as part of the Somerville Arts Council/ArtsUnion.

As seen in Yankee Magazine and Delish!
