all the water on the earth in one place

According to the United States Geological Survey, if you rounded up all the water on the Earth into one ball, it would have a diameter of about 860 miles and look like this. Not a lot of water if you look at it that way, but it is still a mighty plentiful amount if you were stuck, all alone,  in a raft in the middle of the Pacific Ocean (other Oceans are available).
