the nerve of someone making a tutorial to suggest crafting a hot wire with a spare microwave transformer and then end it with "this is by far the easiest way i have cut a glass bottle" 😤 😤
basically the accepted ways seem to be
-douse a string in lighter fluid or acetone, wrap it around the bottle where you want it cut, then set it on fire. douse it in cold water to stress the glass afterwards so it'll break
-buy a bottle cutter
