Every two years, Adelaide hosts the Come Out Festival – one of Australia’s longest-running arts festivals for children.

Curated this year by Susannah Sweeney, Scale Free Network was invited to create a series of art-science workshops, focusing on the River Torrens and its (seemingly invisible) micro-inhabitants.

Over five days, Briony, Gregory and Jacqui ran ten ‘Invisible Torrens’ workshops for primary school students.

We made collaborative drawings of microbial movement by projecting river samples recorded at high magnification, individual water-colour drawing s inspired by microorganisms, and discussed everything from water molecules to water boatmen (insects), viruses to algal blooms.

Thank you also to our hosts, the South Australian Health and Medical Institute, (their amazing building is known locally as “the cheese grater”).
