Thanks for the advice guys but I'm not going to be making any neon tubes any
time soon.  I don't just have glass tubing, neon gas, a vacuum pump, and a
bombarder transformer just lying around :^).  There is a neon sign store
down the road though so I think I'll ask there first.  Maybe they would like
to donate!  If that doesn't work I know school science supply houses carry
small gas tubes like the one peter had in the pictures on his site.  I
suppose I'll give fluorescent bulbs a go too.
