I know for a fact one of the members on here made one and put a video up on Youtube. I can't remember exactly how it worked, but I shall search for it.

I'm in the process of making a sandfall waterfall and taking pic every step.
There's not much info online about how to make but I got it figured out. Pretty simple really. I'll post pics when it's done in a weak or so.
