Re: [TCML] Dry Ice

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

Hi Bart,

Justin Hayes and myself did this a couple years back (2001) on his and Aaron Koscho's 12" coil.  We had hopes of some change in color or other effect, but it turned out to be exceptionally boring. :-)  On the plus side, it didn't create any issues either.

Hi All,
I was wondering if anyone has put dry ice (and water) up in the top load? I'm thinking about the 4th of July this year. On my small 4.5"D coil, my toroid uses to half spheres back to back as the center disc. It is a bowl and can hold a decent amount of liquid. I was thinking it might be kind of cool to throw in some water and dry ice to make some cool clouds (or fog) growing from the toroid (kind of a cloud and lightning thing). I figure someone here must have done this in the past as it's pretty simple to do, so I'm curious if those who have actually tried this ran into any problems? 

Take care,
Bart
