Professor Dan Lathrop and his team from the non-linear dynamics laboratory at the University of Maryland have constructed a 26-ton steel sphere that will be filled with boiling metal and spun.

I’d love to be a scientist. You basically get to buy a lot of stuff, put it together, and then film it, explaining that you’re “generating a magnetic field by spinning liquid sodium metal ...

Inside This Giant Metal Sphere Lives a Miniature Version of the Earth’s Spinning Core By Andrew Liszewski Published December 7, 2011 | Comments ( 0 ) 𝕏 ...

It's still mysterious how Earth's liquid center produces its magnetic field. But one scientist hopes to find clues by building a 26-ton spinning model of the planet.

The sphere the team created, in other words, rotates 500,000 times faster than the average washing machine. Making it, yes, the fastest-spinning object ever made.
