Want to see a cool thing with a CD? Put it in the microwave and set it for 15-seconds and look through the window.

You will see a dancing lightning storm right above the CD, it looks cool.


PS don’t use a CD you value as it will be junk after this.


As far as using a CD to signal, I’m sure they would work. But they are somewhat breakable to pack around.
