- Ferrofluid was originally developed and synthesized under a NASA research project as part of the space program. The fluid is an ultra-stable colloid without agglomeration, precipitation, and separation of the particles. Thus it is capable of defying the force of gravity. It is a stable colloidal suspension of subdomain magnetic particles (Fe3O4 magnetite), approximately 110 Å in size coated with a stabilizing surfactant or dispersing agent which is then dispersed into a base oil. Typical ferrofluid 10^23 particles/m^3 opaque to light.
- Magnets are located in demo 9007 on shelf 56 and the bottom of demo 337 cart by the main door
