Faster CD Shooting

Yesterday, on the popular YouTube channel The Slow Mo Guys, Gavin and Dan uploaded a new video in which they shot in a fast-motion mode (also known as slow motion or just slo-mo) how a CD collapses while rotating at 23,000 rpm . In about a day, more than a million users managed to watch the video.

The Slow Mo Guys team is known for shooting various experiments in a special camera in fast shooting mode. Usually, various processes appear in them that occur too quickly for human perception, and therefore it is not possible to examine them in the usual way. The guys use the Vision Research Phantom Phantom Flex camera for filming.

This experiment was as follows.

The CD was placed on a spinning spindle and started spinning at a speed of 23,000 rpm - this is about five times faster than the disk spinning in a domestic DVD player. As expected, after 15 seconds, the disk was shattered. This process was filmed by a camera with a frequency of 28,500 frames per second, which is approximately 1140 times faster than conventional shooting.

The experiment was continued, and the destruction of the second disk was already shot at a frequency of 61,980 frames per second. This is approximately 2500 times faster than the normal shooting mode.

And finally, the third disk was destroyed at a shooting speed of 170,600 frames per second, or 6,800 times faster than the same process would be seen with the naked eye.
