What about this experiment? Was Neon Tube sources.

["Garry Freemyer" <Garry-at-xxxxxxxx> (by way of Terry Fritz <twftesla-at-xxxxxxxxxx>)]

I wonder if you can take old florescent tubes and use a kind of brush to
scrape the white powder inside that emits light when exposed to an electric
field and paint a sign over a sheet of glass or plastic using clear varnish
or glue and sprinkle this powder over the letters while it is still sticky.

Would the letters possibly emit light when the sign is brought close to the
Tesla coil without needing a vacuum?

I bet this would make a most impressive display.

Harvey, all
    If you aren't looking for any certain designs/ colors of neon tubes, 
check your local neon shop for scrap pieces they have either from taking
down 
old signs or ones that weren't "perfect" enough for sale.
