Is rainwater safe to drink?

On Earth, water gets evaporated by the sun from the planet’s surface, and then drops back down from the clouds when it rains. That’s a great source of water, but..is that water safe to drink?  We asked environmental researcher Dr Jonathan Sexton to help us find the answer. Got a question in your bRAIN?
