The project chosen was proposed by Nathan Freeman. Eggshells were chosen by Nathan because they contain chemicals that act as neutralizers for the acidic ions from the acid mine drainage.
They would use the eggshells to create sculptures in the shape of the problematic ions found in the creek as a statement.
When students returned, the eggshells were dyed a beautiful and disconcerting orange from the metals in the water! This was a strange twist to the project that gave added meaning to the work.
