On August 13, Los Angeles Mayor Eric Garcetti along with officials from the water department watched as the last 20,000 "shade balls" rolled their way into the city's largest in-basin water reservoir. The release marked the final phase of the project that involved covering the 175-acre lake with 96-million four-inch black plastic balls. Their purpose? To provide shade and improve water quality.

          I think it was a cool idea but what if there was a very powerful tornado, a hurricane, or even a strong thunder storm. I would not like if a bunch of 8 ounce black plastic balls flying into my house and breaking my windows! "You scientists think of everything." SAID NO ONE EVER!!!!!

                Do you think this solution would work in a place prone to severe weather?
