Niagara Falls, ON | This is the coolest Christmas decoration I have ever seen said by »tesladownunder.com/Xmas.htm :
Merry Christmas! This is a single photo from a Nikon D70s digital camera and is a 91 second exposure of a real functioning Tesla coil and is the result of perhaps 50 hours of preparation.

Haven't read the original article yet, but I'm curious how they got the sparks coloured... filters perhaps? |

| Oh you can order coloured electricity from HydroOne.
Most people just default to the colourless generic stuff but sometimes when you want to show off to the neighbours... Costs a bit more but sometimes ya gotta pay to get what you want.

said by Devanchya:i'll read the article in a second... but wonder if changing the metal can create colors. doubtful though The metal doesn't matter much, you should be able to change the colour by using different gases. Because the light is generated by plasma, the colour is dependent of the emission bands of the gas atoms.
<nerdy stuff>
For example, the electrical sparks in air have the blue tint because of the 428 nm emission line of the nitrogen (blue-violet) and the 460 nm emission line of the oxygen (blue). To obtain different spark colours you'll have to replace the nitrogen and oxygen with other gases e.g. containing sodium for yellow (589 nm emission line - kinda' hard to make at home).

Changing metals only works for colouring flames...  As for changing the gases - that's a whole lot more complicated and expensive than this setup was.
