DIY:Glass Bottle Speaker - Jack Daniel's whisky bottle

I reused JACK DANIEL 's whiskey bottle and made a speaker.

Previously, I made a spherical glass speaker.

However, due to insufficient capacity of the air chamber, no sound is heard.
So, when I looked for a glass container with capacity 3L - 5L, I found a bottle of Jack Daniel 's.
(Actually 4L was good, but I could not find it.)
Since it is a rectangular bottle, you can use it as it is.

Good quality of glass came out and it became a wonderful speaker.
