Our first question comes from Dianne Schloesser (@lady2Di4).

Q: "Is it true that low barometric pressure can crack or break my windshield unless I lower my windows a crack?"

A: Nope. The change in barometric pressure resulting from a hurricane likely would not crack your car's windshield, says theoretical physicist Michio Kaku. For starters, it takes a lot to crack your car's safety glass, but moreover, pressure maintains equilibrium pretty quickly. That means the pressure inside and outside your car are the same, reducing the chances of a vacuum being created and the glass cracking. Leaving your window opened will just cause wet seats.
