i got an aquarium heater today, at last, which i had planned to use to keep my yogurt brews at a perfect temperature

it tops out at 34'C but i think that works out fine actually, just funny, because of the acoustics of the pair of plastic tubs i got for keeping this thing contained, when the heater is heating the sound of it heating the water makes a distinct quiet rumble

yogurt brewer goes "MUMBLE"
