Work continues apace here in the dirt lab. Saturday is going to be a "Big Day™" around here and I've been building and refining a bunch of demonstration props. Most of the major cutting and assembly is finished, but now comes the tedious fiddling and tweaking to get them camera-ready. I'll have more details and some build photos after we're done filming.
Right now, everything seems to be working out well, but that's in large part because I haven't added water yet. If you want to watch several hours of hard work go "blooie" in a spectacular fashion, be sure to add some water. This goes double if that water is at above-normal pressure.
