Fan from the CD-ROM do it yourself

The question of where to put old and unnecessary CDs (once the recent “death” of HD DVD comes to mind) is, of course, not the most relevant. But if you just throw it in the trash - not your method, then you can come up with something interesting. For example, a USB fan. To build it, you will need an unnecessary blank, a cork from a wine bottle, a few wires and a small motor. The most difficult thing is, of course, to find a motor. Collect something not a problem: a video instruction is attached.
