how to break glass bottles where you soak yarn in acetone, tie it around the bottle, light it on fire for 20-30 seconds then submerge it in water and the glass seperates. However, explain how all this works. Such as, why do you use yarn, why not any other type of string? Why acetone, and why not lighter fluid or gasoline? What makes the glass break?
