Ferrofluid, first developed by NASA in the 1960s, consists of nano-sized magnetic particles suspended in a liquid. Your students will be fascinated as you demonstrate the unique properties of this nanoscience material and produce interesting 3-dimensional magnetic sculptures. ChemFax with suggested demonstration instructions and handling tips is included.
Concepts: Nanotechnology, magnetic properties, colloids vs. solutions.
Time Required: 15 minutes
Materials Provided: Ferrofluid, 50 mL
Note: A magnet is required and available separately.
