Editing Tesla Coil (section)

== Demonstration ==

Preparation: Place the small coil on the stand, aligning the black-spot leg with the black-spot hole. put the large coil inside of it and onto the stand, aligning the port at the bottom of it with the ports on the small coil. Place the metal tip on top of the coil. Plug the red power cable into the port on the large coil, and connect it to one of the three vertical grounding ports on the circuit box. Plug the green cables into the small coil, and connect them to the two horizontal ports on the circuit box. Plug the grounding rod into one of the three grounding ports. Open the circuit box, and check the spark gap to make sure it is clear of rust or buildup. If there is any, use the sandpaper to clean off the tips. Close the circuit box, and use the screwdriver to close the spark gap fully. Now, plug the power strip in, keeping the switch in the OFF position. Plug the outlet cable into the circuit box, and place the other end next to the power strip. DO NOT PLUG IT IN YET.

# Explain to the audience that you will be showing them the Tesla Coil, a device first invented by Nikola Tesla. Alert the audience that it will be a loud demonstration, and that any individuals with implanted devices should stay at least 15 feet away for this presentation.
# Explain to the audience the different parts of the circuit: Transformer, Capacitor, Coils, Spark Gap. you can use the coils as an example of a transformer. State that the spark gap is the limiting factor in this system; If the spark gap stays small, the bolt will stay small, and if it gets bigger, the bolt will as well!
# Put on safety glasses and pick up the grounding rod. Explain the purpose of the grounding rod.
# Have your co-presenter sit next to the circuit box, away from the coil and within reach of the power strip. explain that they will be controlling the spark gap, and therefore the size of the bolt. Have them plug in the circuit box to the power strip while still in the OFF position.
# When ready, hold the ball on the end of the grounding rod against the tip of the Tesla Coil. Give your co-presenter the OK, and after a brief countdown have them turn on the coil.
#* When first turned on, there will be a small spark or no visible spark, depending on how open the spark gap is. Have your co-presenter open up the spark gap with the screwdriver slowly, allowing the bolt to gradually grow larger and larger. As this happens, slowly move the grounding rod further from the coil, so the audience can see how big the bolt is getting.
#* When the bolt starts to get bigger than 6in, do not let the cord of the grounding rod be closer to the coil than the ball on the end. The discharge from the coil is powerful enough to forgo the insulation of the wire. DO NOT TOUCH THIS WIRE, OR ANY OTHER PART OF THE COIL, WHILE IT IS ON.
#* At some point, the spark gap will get too big and the tips will get too oxidized, and the power will cut out. Have your co-presenter slowly close the spark gap. It will jump across again, but the longer it runs the more corroded the tips will get. Have them slowly close up the gap.
#* Once they close the gap, turn off the power. Ground the coil, and have them unplug it from the power strip.
# After presenting, ask the audience the following questions:
## What color was the bolt? (Blue/Purple) What causes the color of the bolt? (Oxygen)
## What state of matter was the bolt? (Plasma)
## Can anyone smell the odor coming from the demo? If so, what is that odor? (Ozone)
