I woke up this morning to find a burning smell in my house, and an electrical circut dead. I traced it to the heater in my CO2
waterbath. I'm not sure if evaporation had lowered the water level too much and caused the burnout, or if the heater had failed and caused the water to boil off. Either way, I'm thankful that the waterbath is made of inflammable glass, and the circut breaker did it's job!
