Magnetic ferrofluid sculpture

From New Scientist: "This video shows moving sculptures made from magnetic ferrofluid.

"Gary Lee Johns, a physics PhD student at Johns Hopkins University, combined commercially available magnetic-particle-infused fluid with a variety of different metal shapes.

"The shape of the metal objects determines the shape of their magnetic fields, which in turn sculpts the fluid, roughly revealing the normally invisible magnetic fields.

"In the video you can see fluid bunching up at points, corners, and edges. Johns says this is because magnetic fields tend to be strongest near sharp edges.

"Ferrofluids could be used as deformable mirrors for telescopes and other optical devices, or incorporated into clothing to make nanotech body armor."

I love the idea of a sculpture that could actually be a fountain of sorts. What a very cool idea for architecture.
