That video sure as heck makes it look appealing! And naturally I'm wondering if I could add dyes/food coloring/whatever to make it colored.
The more I think about water vapor, the less worried I am about rust and such. Just because open hearth stacks are so stinkin' tall. I can't see rust being an issue with nickel tracks and painted locos and rolling stock. Maybe I'll set one up when I get the track done and just let it spew for a month and see what happens.
