Pictured here is a magnetorheological fluid, known as MRF excited by the magnet of a magnetic parts holder. Our initial ambitions were not much of a success due to the strength of magnets we were able to find not meeting the required forces to obtain the behavior we anticipated. This “fluid” was very viscous, that of petroleum grease, and acted as a liquid until excited by a magnetic force, at which point it solidified and became more rigid. This is demonstrated at the top of the image, where the smooth, fluid-like substance transitions into a stalagmite-type structure closer to the magnet.
