2 very good answers involving, of all things, water!! Who would have guessed that a stream of water, being fluid, would be able to lift and rotate a solid round rock weighing many hundreds of pounds?? Man, ya just can't make up a story like that!!

Well, it's faster and very much easier than chiseling a really Big rock into a perfect cube?
