If you don't watch the whole thing, you wont get it. Just like if you want to make a baby, and you stop too soon, then you wonder why you failed.

The Google balloon satellites communicate with each other over 60 miles with a laser beam, which is perfectly straight and parallel to the flat motionless ground we live on.
