READ THE WOLE INSTRUCTABLE BEFORE BUILDING!!!
Step 1: Danger!!!!
Step 2: What you need
Sheet Metal, Mine was 12x18 but you can go larger or smaller if you want ($5)
Page protectors ($3 for 100)
Speaker wire($5 for 100 feet)
Rigid Copper Wire(Depends on where you buy it, 1foot should only be a couple cents, you need 3)
Neon Sign Transformer($25 on eBay)
What you need to take the photo:
Digital camera that can take a long exposure (10 seconds minimum)
Small metal objects, or you can dip plastic items in salt water.
Total costs: about $35 but if you use a flyback transformer or other high voltage source it will be cheaper...
Step 3: Making the Discharge Plate
In this step you will need:
Speaker Wire (2"
With the ducttape, kneel on the floor with the metal plate vertical between your knees and fold the ducctape over the hotdog way' so that half of the ducttape is on the front and half of it is on the back. I went over each edge twice for added thickness but you don't have to. Repeat this steps on all of the sides except for 1. The side you don't tape should be one of the shorter sides.
Now set the plate down on a table with the tape-free side facing you. On the lower right corner slice off the last inch of tape (shown in picture three) remove the tape on that last inch on the top and the bottom.
To connect the speaker wire, strip both wires, about an inch long and tape one of them to the top of the plate and the other to the bottom (see Picture four and five) after you have connected the wires, finish putting the ducttape on the last edge.
The other end of the speaker wire you will need to strip and wind the two separate half of the wire together, this end will go to the NEGATIVE terminal of your transformer.
If you dont know which end is the negative, find a grounded object and touch each end of the transformer to the grounded object, one of them will spark, the other one will do nothing, connect the plate's wire to the one that does nothing.
Step 4: Making the sparks.
Step 5: Taking the Picture
Step 6: The use of my kareoke machine
Step 7: Optional Discharge Plate
Step 8: Page protectors
Step 9: Finished Picture!
Have fun, but be safe!
