Miniature Lightning
A Van de Graff generator works by creating a large static positive charge on a metal dome. When a metal ‘wand’ connected to the earth is brought into close proximity to the dome, negatively charged electrons jump the gap, creating a blue spark. For more on how you can use static charge & how to use a Van de Graff generator to make a ‘lightsaber' check out the source video: http://youtu.be/0OczYKJPNps
