How are coffee and air alike?

This is a fun thought experiment! Here are a few ways coffee and air are alike, playing on different meanings of "alike":

* Both are essential to many people: Coffee is a popular morning pick-me-up for many, providing energy and focus. Air, of course, is absolutely necessary for life.

* Both are invisible in their pure forms: You can't see coffee beans until they're ground, and the brewed coffee itself is brown, not the actual caffeine. Air is invisible until it moves or interacts with something (like wind, dust, or smoke).

* Both are mixtures: Coffee contains water, caffeine, and other compounds. Air is a mixture of nitrogen, oxygen, and other gases.

* Both can be "brewed": Coffee is brewed to extract its flavor. In a way, air is "brewed" in the atmosphere through weather patterns and interactions with the Earth's surface.
