Dry Ice

Hi Russel,

An alternative to dry ice and having to worry about the handling, cost and documentation that may be required is the Antari Low Fog machine.

This was teken from the antari website:
"This revolutionary machine is the first of its kind. it produces the ever popular, low lying "heavy" smoke of a dry ice machine, without the inconvenience of dry ice or the potential health hazards caused by dry ice's heavily CO2 laden smoke. Place up to 10 kg of ice into the ice chamber to cool the smoke produced by the 1000W smoke machine contained in this unit. Then watch the floor disappear in ankle deep smoke. Never before has one machine offered this unique, affordable function. 10 kg of ice placed in the ice chamber can last up to 12 hours or 80 minutes with constant use. Full DMX on board means 100% control along with an output for separate units, and the timer remote puts that control in the palm of your hands. Drainage pump can be activated manually or set to automatic for optimum convenience. Try it out for yourself and you'll never go back."

I have used this unit many times before. It's great. You can stop at the Bottle Shop and get some drinks for after the show, whilst getting some ice for your low fog at the same time.
Just be aware of the environment your using it, and the area you need to cover.

If you really need to go bigger there is always something like the Jem Glaciator.

I've used a Heavy Fogger for a show before, the low fog took a matter of seconds to fill a 10m x 12m floor. It was a great effect. I'm wanting to try and fit it into a show where i can rig it from some fly lines and create a waterfall, budget for the heavy fogger is my problem.

Hope this helps an alterante route.
