I get 7 inch sparks with only 16 capacitors! The good news is I have 24 more capacitors! So I should be able to get sparks about a foot and a half long if I use them all! Probably even bigger if I tune it right. I think I will expand it but I will save that for another video! Since I didn't do a great job at explaining how the Marx Generator works you can read the Wiki page on it if you like. http://en.wikipedia.org/wiki/Marx_generator
Thank you for watching!
