In this tutorial, Tony Vo teaches us how to cut a bottle. You will need: a glass bottle, yarn, lighter, sink of cold water, and acetone or alcohol. First, take your glass bottle and tie a piece of yarn around the part you want to cut. Wrap the yarn two times around, then tie it tie it tightly. Now, take the acetone and drop it onto the yarn until the entire piece is saturated. Next, take your lighter and burn the yarn on the bottle. As soon as the flames die down, place the bottle into a sink of cold water upside down. As soon and the bottle is in the water, it will break in half where the yarn is and you're done!
