 From flufferettes to fluff faros, this community knows how to get creative and have fun. To many, the event shows how a marshmallow spread has become more than just a confectionist condiment. Marshmallow fluff is an amazing thing. It's such a Massachusetts thing and a New England thing about people having fun on a gorgeous day in honor of the sticky confection that is marshmallow fluff. If you're not here, you should be and you should be ashamed of yourself for not being here. The festival, hosted by Union Square Main Streets, pays tribute to late Somerville resident Archibald Query, the man responsible for this sweet spread. Compared to last year, this year's turnout was no match. Been coming every year since 2008 and every year it seems to double in size, like literally double in size. Some say the weather explains this year's larger crowd. Weather is much nicer now. It's a beautiful day. Last year it was kind of overcast and actually a little cool. So, and everybody knew ahead of time it's going to be nice right through the weekend. Not for the weather, local bands, cooking contests and messy marshmallow activities all were reasons for fluff fans to come together and celebrate.
