Please choose the correct ending to complete the given sentence: Home and Garden: [header] How to build a vertical garden from soda bottles [title] Cut around the base of one soda bottle.

[title] Lay two most empty soda bottles together so you have a balance of weight and height to support each bottle. Ending2: [title] Stack a plastic cooler or a clear glass wine bottle on top of the soda bottle.

Ending3: Discard base of bottle [title] Poke two drainage holes with scissors, on opposite sides, about three inches above the cap. [step] How big? No bigger than the diameter of a bic pen. Ending4: [substeps] Use a suitable sharp box cutter or even cutting shears to cut a 1 inch (2.5 cm) flap or leafy mold about ½ " in front of where the label ends.
