Testing for Corruption - Felwood

Progress

You take a sample of slime from Felwood and place some of it into the various tubes and beakers on the table. As things begin to boil and spurt, the slime changes colors. When the process slows down and the liquids calm, you see a small petri dish with your altered Felwood slime samples in it along with some other remnants.

Completion

You pick up the petri dish with the slime sample in it. The only way to discern if the samples is pure enough is to open it and examine the contents yourself. Ideally you'll find a sample that fits Chemist Fuely's criteria.
