Turbulent Flow is MORE Awesome Than Laminar Flow

Everyone loves laminar flow but turbulent flow is the real MVP. A portion of this video was sponsored by Cottonelle.

The coronavirus is mutating. But don’t freak out yet.

The coronavirus, SARS-CoV-2, is mutating. It’s true, but that’s not necessarily a bad thing. It sounds concerning — if the virus is changing, that could imply that it’s getting worse. That’s not the case. Although it’s true that the coronavirus is mutating, that doesn’t mean it’s getting more dangerous. In fact, it can help us in our battle against the COVID-19 pandemic.
