Step 1: Materials
cd player(try to have one that you can break like an old one)
Step 2: Combining CD PLayer and LED
Then take the led which is attached to the battery and tape or glue it onto the cd.
You may have to rig up the part that allows the cd to spin once the top is closed. On mine it is a little button that was pushed down from closing the cd player, so I just pushed a little cardboard onto it to keep it down.
Step 3: Start the Show
I used the mode on my camera that exposes over a longer time which resulted in the pics that have the swirls.
I will probably retry this but experiment with different LEDs to get cooler effects.
Hope you like it.
