Awesome! We need a series of studies to increase the amount of water in the Central Valley of California. Heck, might as well do a series of studies on Texas too.
What a boon these study series are. How could I have been so blind?
Some of them get propelled right out of the atmosphere by Sunlight.
They drift further and further away from Earth only to be caught up by the Moon!
These ice crystals are by that time totally sublimated and constitute a form of very cold water vapor. When it hits the Moon it is precipitated out as ice crystals, and piles up over the millions and billions of years. Next thing you know, voila, a Caribbean sized ocean of water every 15 days, and then a Caribbean sized ice cube for the next 15 days.
Smeared out over the surface it'd look like a heavy frost. Slowly the freeze/thaw cycle would allow this water to blast its way into the interior just like it was busting up the street in front of your house in wintertime.
