In the script, a hole in the leg of the astronaut's suit vents a stream of gas after her fall.
Our initial plan was to feed a tube under the suit, leading to the hole and attach the other end of the tube to a powder-based fire extinguisher. HOWEVER, this idea hasn't worked out. The tube gets blocked really quickly and the extinguisher pumps out way too much powder - which additionally is really messy!
What we need it a nice continuous stream of pressurized gas blasting out of the suit - dry ice would be ideal but we've no idea how to make this work. we're also concerned that there might be safety issues with a tube of dry ice running past the actor's thigh.
We intend to supplement the effect with a particle emitter in post, such as can be found in Motion for example, but we would prefer to have a real stream of gas coming out of the suit if possible.
If anyone has any bright ideas about how to make this work - on a budget! - please let us know!

How does just a stream of air blowing the torn suit shreds look? Or does it really need to have "color"?
I'm envisaging something that looks like a jet of steam, essentially. The gas would freeze in the Martian atmosphere, so would be briefly visible, I believe.
Cigarette smoke blown through a tube by a volunteer who enjoys the rich full flavour of carcinogenic substances.
Cheap and readily available. Perhaps the stunt double could blow the smoke herself.
Umm, regarding the cigarette smoke. Maybe you'd need more than one smoker working in shifts to exhale one after the other -- this would allow the jet to be continuous. I imagine some kind of tube with a Y shaped splitter rigged up so each smoker could change turn without and interruption. The tube is routed out of shot down the suits leg or out the back depending on the angle and cropping of the shot.
You volunteering, Parke?
Nope, I've never inhaled -- even though it looks really cool
But smokers aren't all that difficult to find. You can probably pay them in tobacco.
Yeah, I'm not sure aerosol will have enough punch to make it through the tube extending down her leg. I'm currently looking at tracking down a (cheap) C02 fire extinguisher as a possibility, or dry ice in a pressurized container. But still on the hunt really.
Yeah, but is there some way to fudge the camera angle and not have to use the tube and just show a close up of the leak--this way you could use an aerosol can directly out of the suit--meaning no one would be in it--basically, all done with "mirrors' as it were--you could switch between shot of her face, close up of the leak and showing her go for the patch and either another close up of hands patching leak or no shot of patching leak--only show after it's patched. Basically it would be someone holding the can and spraying thru the tear in the suit--you'd never get a full body shot of the leak and astronaut as in the drawing but you would get the shot....

Good thoughts actually. I might have a play with the camera and some sprays in the weekend and see what kind of look I get...
I would use compressed air like from a air compressor. or those cans of air that you blow out your computer with. when they get cold they put out some vapor?
I had another thought. try using a sprayer that you use to kill weeds with. pump it up water about 20 times and see what happens.
