Please choose the correct ending to complete the given sentence: Education and Communications: [header] How to make water rise [title] Fill a pan with water. [step] The pan should be 1-2 inches (2.5-5.1 cm) deep at least. You need a pan that can hold enough water so that it isn't all sucked up into the glass.

Ending1: [substeps] If you don't have water available in your house, you can make your own water. You can use tap water, distilled water, or other water that is not acidic. Ending2: It should have a visible lip from which the water can rise. [substeps] You can buy a pan that's 1/8 inch to 1/8 inch (1.3 to 1.9 cm) bigger than the one you've ordered. Ending3: If all of the water gets sucked up into the glass, then air will be able to get in. Since the water is heavier than the air, it will fall back out of the glass because of gravity. Ending4: Also be sure to keep it at least 1 foot (30 cm) from the pan. [substeps] Because the surface area of water rises, it's important that it stays at least 0.5 or 2 inches (1.3 or 1.3 cm) above the surface.
