With streaming music and digital downloads taking over, what to do with old CDs? Use them in a science experiment, of course!
Gavin Free and Dan Gruchy, also known as "The Slow-Mo Guys," have done just that -- spinning CDs at high speeds and capturing in slow-mo the incredible moment when they shattered. Just check out the video above.

The duo used a vacuum motor to get one of the discs spinning at a speed of 23,000 RPM -- and then used an ultra-high-speed camera to film the CD explosion at a rate of 170,000 frames-per-second.
"That's the fastest thing we've ever filmed," Gruchy says in the video, "and the fastest frame rate as well."
See ya, CDs!
