This time-lapsed footage captured on surveillance camera shows the 4,000-year-old ancient Egyptian relic of Neb-Senu gradually spinning in its display case over the course of a week. For the last eight decades, the statue remained stationary until caretaker Campbell Price noticed a shift in its placement that would return each day after being adjusted. While Price speculates the artifact's movement might be explained by the disturbance of an "ancient spirit," physicist Brian Cox believes that the rotation may have been caused by a process know as "differential friction," in which subtle vibrations can make an object turn on its axis.
