Ah yes, the old bunyip-on-a-board trick. :-) Ingenious. I've put a couple of drops of red food coloring in the ends of the tube for relatively long-distance single-handed use. I used it once to find the height of the scope's objective lens center relative to spot due south atop a neighbor's privacy fence from a permanent vantage point to do meridian passage sights. So far have not laid out out the base for pyramids with a water and a trench.... I like the idea of plastic balls that float. May I ask what you used for the balls?
