the latest post from cooking issues is about using a microwave and a vacuum to dehydrate fruit. in building a jerry-rigged microwave vacuum chamber, what they had apparently not thought of was that "under partial vacuum, microwave ovens really, really want to make balls of plasma. I kept having giant balls of fire shooting off the thermocouple. I ripped out the thermocouple. Then I kept on getting balls of fire coming off my oranges." have i mentioned how much i love cooking issues?
