Fluff Festival

What the Fluff? A Tribute to Union Square Innovation is a madcap festival honoring the invention of Marshmallow Fluff. It celebrates Somerville’s proud tradition of innovation with live music, fluffalicious feasts, sticky games, zany happenings, and much more happening on Somerville Ave (from School St to Washington St).

What the Fluff? is brought to you by Union Square Main Streets, a 501(c)(3) nonprofit organization, with a mission to preserve the unique character and advance the strength of the Union Square business district and community in partnership with the Somerville Arts Council as part of the ArtsUnion initiative to enhance the cultural economic development of Union Square.
