Navier-Stokes video fun, Emriver shipping, Em4.

We had a busy Friday at LRRD.

We’re hard at work on the Em4, and got an exciting and very expensive shipment of exotic materials for it.

Jesse and Cara worked on shipping alternatives for the Emriver. We’re being asked to ship them to far places.

At the end of the day Jesse, Cara, and I had fun testing the new plastic media we’re developing. It’s size-coded by color melamine plastic–we’re putting it in a 90mm diameter acrylic tube and pushing water through it.

We shot the first video at 514 (with the big expensive cams and lights, anyway). A milestone.

Here is “Cow Fossils” on YouTube. The little plastic cows were from an Emriver demonstration.

And a more serious treatment on YouTube with some jazzy music:

And a more academic video showing settling properties of the media and how we filmed it (35mb download).

If you need it, a reference on Navier-Stokes.
