What the Fluff? Festival! Legally Fluff: A Toast to Union Square

This wacky, one-of-a-kind festival honors the invention of Marshmallow Fluff by Archibald Query in Somerville in 1917 and salutes the spirit of innovation that still thrives in Union Square today. Now in its 21st year, the What the Fluff? Festival showcases clever culinary creations, live music and entertainment, and incredible artistic innovations brought to life by more than 100 local businesses and participating vendors.
