Does anyone else have a replicator?

Ever since Nathaniel knew that the letter p said "puh," we have let him put little flat, seemingly empty bags into the mircowave. He reaches up to press the "Popcorn" button and sits back to watch the blag infate. When the bell rings, he pulls out a nice hot bag of popcorn. Well, now that he can read a little bit more, something must have been on his mind for a little while today. About twenty minutes after he made popcorn today, he came up to me and asked, "If you were to put the bag in the microwave and pressed the "Potato" button, do you get potatoes instead?"
