As he ran, Adam pulled up the alert on his smartwatch to analyze the details. A new strain of highly concentrated acidic gas was spreading through the upper atmosphere. The gas molecules were loosely spaced out and freely colliding into each other and any solid surface they encountered. Adam knew this gas could dissolve metal and pose a serious threat to cities if it continued spreading.
Being loosely spaced with free moving molecules, gases have very different properties compared to tightly packed solid metals and their orderly crystalline atomic structures. Adam had to act fast to somehow neutralize this acidic gas before it could react destructively with exposed metals across the country.
