Ever wondered what gives lift to cakes, or why a batch of cookies failed? What’s the secret? Science!

This First Friday, take a journey through the kitchen and the chemistry lab as we look at the delicious side of food science! Join us in exploring the chemistry of baking, browse a pop-up of vintage cookbooks, and learn about the less-than-savory ingredients added to food products throughout history. And—just in time for the holidays—stop by our hands-on craft station to make your own unique recipe card, with inspiration from our historical recipe collections!
