I have cracked CDs before because I was really curious about how far they could be bent and how they would finally crack. However, when I decided to do that again to an old CD which was to be thrown away I wasn't at all prepared for such an explosion. Apparently, CDs of different brands behave differently when threatened in such a way. They all fight back, but this one delivered a final blow at me much stronger than others. But the splinters it left looked interesting:
And I love how they shimmer! :)
On a side note: Today, 150 years ago, Alvan Graham Clark discovered the second white darf in the history of astronomy: Sirius B (white dot in the lower left quadrant of the picture), the tiny companion of the brightest star in our night sky, Sirius A.
