It's called mixology for a reason. On January 20, the Exploratorium transforms into a liquid laboratory to explore the science of cocktails. Guest bartenders from 15 Romolo, 83 Proof, Orson, Alembic, Annabelle’s Bistro and other popular San Francisco drinking holes will craft delicious cocktails while guests participate in hands-on science experiments on the topics of alcohol, inebriation, hangovers, cocktail creation and more. Sponosored by Meebo, this first-time Exploratorium fundraising event takes an in-depth, hands-on look at the physics, chemistry and biology of cocktails.
