CD at High Speed in Slow Motion

Gav and Dan, The Slow Mo Guys, record a compact disc (CD) explode at critical speed by spinning it on a vacuum cleaner motor. The motor makes a sickening whirring as it speeds up and eventually the CD explodes in an instant and a loud “POP!” The view in slow-motion is amazing but not even fast enough to capture much more than a second of shattering at 28,500 frames per second (fps) and the CD is spinning at about 25,000 rotations per minute (RPM). They ramp up their new toy – a Phantom Cinemag 2 v2511 – to an amazing 170,600 fps. But at that frame rate their camera captured 7 hours of video – 96 gigabytes (GB) of data – in just 4 real-time seconds!
