Salty Sparks - Colouring an arc

A page dedicated to trying to get different colours from a Tesla coil arc
Usually a tesla coil will give purpley-blue arca to air, due to the nitrogen in the atmosphere
But, if you load the breakout point with salt, Yellow arcs can be made.

This was my first attempt, these were created by dipping a wire breakout with salt and running the coil. the arcs on this page ar only about 5cm tall, as the salty effect won't affect bigger arcs.
