A friend of mine wants to embed his space rocket into the sand on the beach, as though it had crashed the previous night. (He built it for a carnival!)
He would like some wisps of smoke eminating from it and asked me if I knew of a method... I have a couple of smoke machines, but obviously, there is no power on the beach! Considered dry ice, but it's hard to get locally and in my experiance doesn't work particularly well unless you immerse it in a boiling kettle of water. Anyone got any suggestions? Whatever it is really needs to "smoke" for half an hour or so before being "recharged". Heat isn't a problem as there will always be someone around to keep the kids away, flames might be problematic as most of the rocket is made of wood! Thanks in anticipation! John |

You can get a fog machine that delivers the fog to the ground via ice. Also, dry ice works well, even with Luke warm water - though it will not last for a half hour unless you have a ton of dry ice and flowing water.

For something that is outdoors, a small amount of fog will not do. for that long of time, I think that dry ice is your only option. Once the water it is immersed into gets cool, the production of fog slows down a lot, but that is also good for you, since it allows it to last longer. What happens, is the water actuall freezes around the dry ice, and forms an insulating cover for it.
But, for that length of time, you aren't going to be able to generate huge amounts of fog. So, you are going to have to design it so that the fog comes out of a small outlet, as opposed to just a general smoke emitting from the wreck. Otherwise, the fog may not be noticed before the wind blows it away. Since it is a beach, here is a suggestion; Dig a hole, roughly half the size of a bath tub. Put a large plastic garbage bag into it, and fill with ocean water. Then, dump your dry ice into it. Buy at least 10 lbs to experiment with to see how long and how well it holds up. You can fasten some sort of tube to direct the fog in the top of the bag. Joe Dunfee

I just remembered that there are propane powered foggers used to for mosquito control. If you got a new one, and used the standard theatrical fog juice, you might be able to crank out a lot of fog for the time you need. I don't have any knowledge of how long they can go between refills. They are around $70 at the big hardware stores.

The generator is probably your best bet, unless you have a lot of time to experiment with the dry ice suggestions you've received. Do you have access to a generator?

It would seem that joespuppets is right on the money. A gas powered generator does seem like the logical solution. You never know when you might need something else electric while filming.
