In this experiment, students make "ferrofluid", a colloidal suspension of magnetic nanoparticles. Ferrofluids respond to an external magnetic field, enabling the solution's location to be controlled through the application of a magnetic field. This again highlights to students a change in material properties at the nanoscale.
