Please choose the correct ending to complete the given sentence: Food and Entertaining: [header] How to make citrus popsicles [title] Pour lemonade into four popsicle molds or plastic cups. [step] Don't fill them up completely because when they are put in the freezer, the lemonade may go over the brim because it will expand. [title] Place the popsicle sticks in the middle of each mold.

Ending1: [step] Make sure not to spill any lemonade while you doing so. [title] Freeze for about a day or until they are fully solid. Ending2: [step] Check for holes in the sticks or holes that will stop the popsicles from fully blending. Try to fill each mold evenly, for a small section will still be active while you fill them up. Ending3: [step] Place the popsicles according to your taste, but a good rule of thumb is 3 by 3. ( or a stick that's 32 by 2½ inches if you're worried about the popsicles falling off). Ending4: [step] Remove the stick from the molds once it's poured a little into the other two molds. [title] Fill to the brim with ice.
