Step 9: Enjoy and impress your friends!
Well, there is the instructions to make your own Plasma Speaker! Go ahead and pump in your favorite music then listen and watch the arc dance with the music and admire what you had built...
Then show it to your friends and family, I can guarantee you they will be greatly impressed.
When my Dad first saw my plasma speaker in operation, his first words about it are: "What the f... Tha... Thats impossible." He is wrong, nothing is impossible... Nothing.
