The College of Arts and Crafts Sciences is having a fair, and its happening now, on College Green. Academic departments will be giving away free food, including ice cream made from liquid nitrogen (cool, Chemistry) and cheesesteaks (what up, Urban Studiez). If you’re not dieting in preparation for fried Oreos at Fling, perhaps it’s worth a trip. A number of prominent professor types will also be giving 60 second lectures. The fiesta rages until 3 p.m.
