Dear 100 Hour Board,
As I have been sitting here at work, absent-mindedly staring at the poor students studying at 10:27pm on a Saturday night while the Stadium of Fire is well under way, I suddenly had the most random thought pop into my head. HOW DOES INHALING WORK? I understand exhaling - the contraction pushes air out. But how do we suck it IN? Does it work similarly to a vacuum? (Do I even know how vacuums work? Difference in air pressure, right?) I just suddenly felt bam-boozled and like I needed an answer.
This Youtube video explains it pretty well.
