On 28 August 2013, scientists at the University of St Andrews (UK) published results of their research, which created the fastest rotating manmade object to date. The team created a tiny sphere of calcium just 4 micrometres across, around 10 times narrower than a human hair. Suspending the sphere with laser light inside a vacuum, they made the sphere spin by altering the polarity of the light. The calcium sphere reached 600 million revolutions per minute (RPM) before it disintegrated.
