Dave and Nastassia return this week after a lecture at Harvard to discuss the best things Dave’s ever gotten out of a rotovap, as well as the best practices for cleaning one. They also take questions on the future of Searzall sales, liquid nitrogen ice cream, and egg-free cakes. Dave goes into detail on how to set up a bottle-style carbonation system. This program was brought to you by Wilma Jean.
