Joule Thief Night Light

A Joule Thief night light made from an empty plastic water bottle filled with glass spheres and plain water. Powered by a single AA battery. (This is the same AA battery used in all of my video experiments to date) This is actually a lot brighter than it appears in the video. For more information go to Overunitydotcom in the Joule Thief topic. Thank you.
