Unequivocally yes… which is why I wasn’t surprised when the first publicised reproduction involved a tiny grain, why the big pressed pellets seem to be staying put, why people are suggesting breaking the samples up, and why the original pictures/video showing the levitation that kicked all this off, is an oddly shaped sample that sort of looks like it flaked off a larger piece.

Smash the samples… see if any of the grains float… (it’s becoming a bit of a refrain on Twitter whenever a big chunky pressed pellet sample is published as a failed replication) … it won’t be hard to improve the process and try and get larger contiguous samples that show the effect once we know for sure that it’s actually happening even if it’s happening in smaller more obviously superconducting samples, be it the size of a sand grain or a grain of rice, as long as it’s clearly a room temperature superconductor… once we have more samples… the analysis experts can get stuck in, there’s a global army of analytical experts… crystallographers, spectrographers, and all the sub disciplines of analytical chemistry… with clearly superconducting samples these people can swing into action and work out what the magic is and what we have to do to make more and bigger floating rocks.
