This literal ball pool might look like fun, but it actually has a very serious reason behind it: preventing drought.

A pilot project at the E.M. Johnson Water Treatment Plant, it was a move enforced by the city of Raleigh, North Carolina, in the US, as it faced a water shortage.

The move is designed to prevent water evaporating in the height of summer – as well as algae growth caused by sunlight.

Algae can affect the taste and odor in drinking water – but is very difficult and expensive to treat with chemicals.

Referred to as ‘Shade Balls’, they’re lightweight, inexpensive and the four-inch plastic toys will eventually cover the entire reservoir.

That amount of lithium is enough to power more than 382 million batteries for electric vehicles.
