I'm completely out of my league here. I was looking at the floating sample picture and it struck me as odd how the material levitates at an angle. [0] The broken part floating and the "pressed" part resting on the plate. To me, this suggests that a significant amount of the material is not the target material. Further, if the target material was evenly distributed, I'd expect that levitation properties would correlate with the thickness of the piece and the piece would float, evenly. Right, if a 1mm piece has 1unit of levitation, a 5mm piece should have 5 units of levitation. If the 1mm piece levitates, then the 5mm portion should as well. Since it's not levitating evenly, I suspect the target material is unevenly distributed. Further, I'd argue that the target material is actually consolidated to a single piece of that sample. Perhaps (conjecture) that little silver spec near the tip of the crack. From what I've been reading, it seems like it's very, very hard to trick the copper into the right place. It seems possible that the process does work, but a lot of luck is needed to create a large enough piece to support the levitation effect. It's almost like someone stuck a "super strong" helium balloon in the center of a half-eaten cake. The helium balloon lifts the cake, but the weight of the uneaten half of the cake causes tilt. 0 - https://www.newscientist.com/article/2384782-room-temperature-superconductor-breakthrough-met-with-scepticism/ https://www.newscientist.com/article/2384782-room-temperatur...
