[TCML] Dry Ice

[bartb]

Hi All,

Thanks for all the tips. I learned a lot here. The fog rising (fog 
machine) or falling (dry ice) is interesting. Spillage of course is a 
concern, but easily controlled. The center bowl is stainless, but I 
would be wise to simply insert a plastic bowl. I won't be using my spun 
toroid but a smooth Al foil toroid, so no big deal there with pitting. 
What concerns me is temperature. July will be hot here (+100F). With dry 
ice, I expect the fog to roll down the outer portion of the toroid and 
head to the primary rather quickly (of course if there's a wind, then 
it's a no go). I'll have to do some test runs and see how this reacts 
outdoors.

I'm not looking for any other effects expect a cloud and lightning show. 
This little coil puts out some hefty streamers (12/200 NST), so this 
could be an issue if the fog guides the sparks, although I do have the 
primary under acrylic, the bottom of the secondary would be a likely 
target. This might be one of those times that I may actually use some 
strike spheres or maybe even a ring. Come to think of it, I have a 
chrome 1.5" diameter tubing which may be perfect for this setup (the top 
ring to a clothes rack used at department stores, about 4 foot 
diameter). I simply need to gap it and mount it.

Thanks for all the comments and experience in this area.

Take care,
Bart
