Revel in the glory of all things fluff when, on Saturday, September 25th, Union Square hosts its fifth annual What the Fluff Festival. This year’s festivities, which honor the sticky substance’s creation in 1917 by Somerville resident Archibald Query, will feature musical performances, games, a poetry contest and various other ooey gooey shenanigans. You can also try your hand at whipping up a marshmallowey treat and submit it to the cooking contest – Hell’s Kitchen Finalist and Gargoyles on the Square chef Jason Santos will be amongst the judges. The fun runs from 3-7pm – check out their website for more information.
