Maybe ‘shade balls’ should not be balls
So-called shade balls have a range of uses in water reservoirs, from cutting evaporation to reducing the growth of algae. But the best performers might not actually be balls, a Florida teen now shows.

Cleaning up water that bees like to drink
Plant roots suck up pesticides used on soils, then release them into water that can seep from their leaves. This is a sweetened water that bees love to sip. A teen figured out how to remove most of the pesticide with bits of charcoal.
