We arranged the cards by number of grobles because we saw that every card had a number of grobles which was exactly higher or exactly lower than another card. Also the cards reactions and colours are almost exact when we line them up using grobles. For the Phoregums we placed them between grobles gaps and numbered it and matched the reaction and colour as well as the state to the substance.

I learned that chemistry uses more thinking than I anticipated and that there is always new things that can be learned.
