This is not a water bottle, this is an echo machine;
If you speak into it, your voice echos around the Earth forever;
The lid looks battered, but it’s where echos have bounced off it into the air;
The paint is chipped, but it’s where echos have been absorbed into it to save its power;
Many years ago, the machine was created, and the first ever sound was made;
This is not a water bottle, this is an echo machine.
