I have a small stage that I would love to make a fog curtain outdoor screen for. I have wondered why the screens I see seem to blow the screen UP... against gravity. I would presume gravity assist would be nice and imagine blowing a screen down would allow the cooling droplets to reflect a bit longer. I am new to this- so my ideas may be naïve- feel free to correct me! I will presume little to no wind- no fighting nature. Do you have any links or ideas to further building a screen for an aprox 12 ft backdrop to get me going?
