There have been a couple of videos of magnetic putty floating around on the net recently. I think this is my favorite. It shows items being devoured by a special putty with magnetic properties in significant detail. I think of it as four minutes of alien digestion. Sounds gross I suppose, but it's quite cool actually. It makes me wonder if, over time, this putty will form itself to match the magnetic field around a strong magnet. We've played with ferrofluids, but this oozy, gooey putty seems like a whole different kind of fun.
