MIT Museum's annual school vacation week festival, Feb Fest, provides daily activities for the whole family! This year's theme is "Assembly Required"--think designing, building and making. Drop in and play with chain reactions with How to Build a Better Mouse Trap. Visitors will work in teams to design a contraption that catches a toy mouse in elaborate ways. MIT students will also be on hand to showcase topics like electronics, biology and motion. Curators will give guided tours of their favorite galleries.
