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 Saturday, September 17 from 3-7pm in Union Square (rain date Sunday, September 18).

Union Square Main Streets and the Fluff Planning Team is seeking volunteers to help make this year’s Fluff Fest the sweetest festival yet! Over 100 volunteers are needed for the festival to run smoothly.
