The kitchen stuff? There's lots of dials and buttons involved. One is like a large box that you put food in to be cooked in using extreme heat. And a different sort of box that can preserve food by keeping it real cold; a part of it can even hold ice.
Oh—! And then there's the whole thing about running water! It comes from a pipe, and you can even control the pressure and heat! It's all over the place. The kitchen and bathroom, though, especially.
