Martha Stewart shares a Good Thing for pre-scooping ice cream, then shows one viewer how to re-pot a cactus. To save a little time at a party, prepare perfect scoops of ice cream for your guests ahead of time. Cover a cookie sheet in plastic wrap for insulation, and then begin scooping. To get smoother spheres, dip the scoop in cool water as you go. These single-dip servings will hold their shape in the freezer until you're ready to transfer them to bowls.
