Use a glass cutter to cut a small hole in the bottom of the bottle or jug.

Step 3: Blow Across the Hole That Is Already in the Top of the Jug

Position your lips so that you're blowing horizontally right over the opening. Keep blowing until you get a clear note. This may take a while, so be patient and keep practicing.
