Hello all! My name's Trane, and I'm a multimedia professional by trade, but a novice inventor in my spare time... I'm eager to learn about EM field manipulation and ferro fluids! I've got a science project in mind... I'd like to come up with a way to measure the "RIGIDITY" of ferro fluid under the influence of an EM field. But I'd like to see if it's possible to inject ferro fluid into a balloon, bag, or bladder, filling it with no air pockets... then applying a magnetic field from OUTSIDE the bladder in hopes to manipulate the bladder's shape. I want to measure how rigid the fluid in the bag gets. Does anyone have any suggestions as to how I can scientifically measure the rigidity? I'd like to come out with some kind of pounds per square inch model.... but I'm not sure how to set up that kind of measurement. Any suggestions? My goal is to see if it's possible to create primitive shapes like cubes, globes, and cones out of the baggie filled with ferro fluid. And to see how solid they can become. Any help on this would be greatly appreciated!
