Definitely have the formulas for every powder, maybe some uses, and a very specific flow chart of how to identify every powder.
Based on what my partner was doing, know how to do sheet chromatography (i.e., multiple samples on a single sheet, rather than individual strips) and not necessarily with pens (at Nationals it was juices), density tests for the polymers, and weird types of hair/fiber (apparently there was bat hair at Nationals).
Also, for this event writer but also for the event in general, you need to work fast
. 207 questions is a lot to do in 50 minutes.
