This is neither an acquisition nor a work-in-progress... my camera is in use right now at the lab, but I stole it back for a shindig at the Science Museum yesterday. I took the Small Child; cuteness factor in safety goggles while excavating fossils, and later dressed in too-large lab coat, safety glasses and disposable gloves, was off the charts. There was an exhibit of naturally-dyed wool, all from plants except for the indigo in the center. There were claims of books on natural dying in the gift store, but we were having too much fun to check that out.
Photo of the part I am tangentially responsible for:

Small Child liked the engineering at the side - he built a ring dam that kept in water, and learned about maximum water depth due to angle of repose, and deepened the pond by expanding the diameter of the dam. I like the middle, natural part the best, though.
