The solar eclipse is a multiple step process and is extremley difficult (Best done in a dark room).
1. Stretch your ball
skin so it resembles the move the batwing
2. You put a flashlight behind the stretched
skin. If done correctly there should be a white circle, the "sun".
3. Then take your other
hand and slowly push one of your testicals across the circle of light.
4. Admire your great feat.
The difficulty is holding the skin
tight while holding the flashlight in place while pushing the balla across.
