I know summer is all about sun, but I happen to love the sound of rain, especially late day showers!
I love the sound of rain which is liquid water that condensed and became to heavy and then falls.
how does the rain get so condensed and fall into drops?
It is from the atmospheric water vapor.
wow I wonder if it's safe?
I would think so as it provides good conditions for different types of ecosystems  and helps out with crop irrigation. 
yes I bet natural water would be best than man-made.  SO rain is amazing to listen to and know that it's feeding crops that feed me, right?!
That is so true! It also gives us almost all of the fresh water on Earth!
would it be safe to drink?
I believe so. That would be the fresh water.
