That is absolutely brilliant. Even if we wanted to we couldn't build one now, as we rent and the fridge is part of that. Our fridge is quite small so it's pretty much always full of food, but I will remember to add liquids if it gets low. We also use it to defrost our meats, so that keeps it colder too.

Oh, and you have full permission to spam my posts with wonderful, relevant details in the comments. That's not got much spam in it! (said in a Monty Python voice)
