Geobong V is a success.

OK, the first thing we need is a socially acceptable name for this device, because the joke name that stuck to it is not going to work.

Aside from that, today’s first run for this prototype was beautiful. It contains media in four sizes/colors, and does a bunch of things well. Here you can see, with the pump off, the settled layers, and also a beautiful separation with water flowing upward through the column, with particles sorted from large to small.

Movement of the particles is mesmerizing, and an injection of air at the bottom forms complex vortices. We’ll be developing this further, it has a lot of applications.
