In remnants (entropy collection) (2018), both artists Ferracin and Tolcher displayed their organic and inorganic experiments as if they were in a scientific laboratory. In 30 cell culture plates, each with 48 Well cells, both artists demonstrated entropy in a natural and artificial way after oxidising weeds (Ferracin) and metals (Tolcher). Dr. Robert Baker - their mentor from the University of Sydney - comments that " ... [there is] a big difference between the two, however, it is that while the weeds can exist in harmony with their ecosystem, the entropy price of making metal is paid for by the production of carbon dioxide which may end up causing the whole house of cards to collapse."
