This a fairly simple way, to make light motion pictures.
Things you need.
A watch battery (CR3052) (mine was in a broken watch)
An old cable. (I used an old cut up usb cable.)
What to do.
1. If it is in a watch, open it and take out the battery.
2.Check the led to make sure it works. The longer leg is positive.
3. Tape the led and battery together.
4. Tape or glue the ‘throwie’ to the cable.
5. Take awesome pictures
