Ok I don't mean to be pedanntic but a sphere is just the boundary of a ball. If we are trying to capture volume we should be talking about balls of water.

Counter pedant: a ball is indeed what you get when, as in TFA, you put water “in a sphere”

I agree. It's a volume of water bounded by a sphere. I'm just being pedantic about the common use of the word in this thread.

I'm also somewhat surprised no one else was being pedantic about this. I expect better from HN :)
