The sound of the top popping off a nice frosty cold one is music to our ears. Drinking it, however, is much better out of a glass. The beer gets some much needed air and, more importantly, gets that delicious head. The glasses you already have will do the same thing as this Hopside Down glass, but they won’t look nearly as good in the process. Crack a cold one and pour it into this optical illusion and you’ll get all the benefits of glass and it will look like a bottle.
