Highest manmade RPM According to Official Guinness Records,
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.
