How Humans Make Rain

The sky holds millions of tons of freshwater, a precious commodity with our growing needs on Earth. Since 1946 scientists have been developing cloud seeding — techniques to squeeze water from clouds for areas suffering from drought and other shortages.

Investigate the science behind the rainmaking that can benefit so many around the globe.
