    TLDR:

    • Meisner effect caused by ferromagnetic impurities, wasn’t actually levitating, just parts of it were repelled by the magnet.
    • Extreme change in resistivity at 104.8 degrees C caused by internal copper sulfide molecules, which exhibit a phase change exactly at that temperature.
    • a team grew a single crystal version. It’s an insulator.
