Farewell, ball pit

The coronavirus pandemic could change parts of our lives in some unexpected ways, for years to come. Our reporter looked at some of the mundane things we might not see as much.

Letting your kid jump into a ball pit. Swimming around in a pool of plastic — a material experts say is especially good at harboring germs — could become a thing of the past, at least at McDonald’s. “There’s probably some good public-health reasons not for us to be doing a lot of ball pits,” said the company's chief executive.

Plastic makes a good carrier for germs, health officials warn.  Sergei Petrov\TASS, via Getty Images

It has left more than 1.1million Americans without power

A derecho (/dəˈreɪtʃoʊ/, from Spanish: derecho [deˈɾetʃo], "straight") is a widespread, long-lived, straight-line wind storm that is associated with a fast-moving group of severe thunderstorms known as a mesoscale convective system.^[1]

Derechos can cause hurricane-force winds, tornadoes, heavy rains, and flash floods. In many cases, convection-induced winds take on a bow echo (backward "C") form of squall line, often forming beneath an area of diverging upper tropospheric winds, and in a region of both rich low-level moisture and warm-air advection. Derechos move rapidly in the direction of movement of their associated storms, similar to an outflow boundary (gust front), except that the wind remains sustained for a greater period of time (often increasing in strength after onset), and may exceed hurricane-force. A derecho-producing convective system may remain active for many hours and, occasionally, over multiple days.
