How can I effectively cut the side out of a wine bottle?

To effectively cut the side out of a wine bottle, you can use a glass cutter to score a line around the bottle where you want to cut. Then, carefully heat the scored line with a candle or other heat source. After heating, quickly cool the bottle with cold water. The thermal shock should cause the bottle to break along the scored line, allowing you to remove the side. Be sure to wear protective gloves and eyewear while doing this.
