This is the latest gadget that will soon be gracing my kitchen. Ditch the stackable measuring cups and spoons, this is truly the only device you need for measurement. Slide the knob and the cup part will adjust to your desired measurement. The bigger of the two can measure up to half of a cup and the smaller one can do everything below two tablespoons.
They are also magnetic—so stick them anywhere: the fridge, stove, metal plate in your head, etc. They are available over at the MoMA Store for $33.
