This took about 5 hrs to build, made with a glass inscense tube 2 blue LED's white bradied heat resistant tube I found in a toaster mmmmmm toast... , 1/4 copper tube and a copper plated plumbing hanger bent to my will with a hammer, couple brass fitting off a gass grill and brass plated RCA connectors.
and my personal favorite the High Voltage tag i pulled off an transfomer out of a TV. Runs off a button cell (3v) stole the button cell tray out of an old motherboard. The copper wire I wrapped around a wooden dowel to get the spring shape. The inside tube (under the glass) is a clear pen body.
