All you guys up north in the snow belt probably could not care less about this, But here in North Carolina we do not get alot of snow, So I figured out to make a snow machine out of galv pipe 1 oil nozz, and 2 natural gas orfices (Modded) out of a gas pack aldng with a pressure washer and a air compressor. Took alot of trial & error. But it made enough snow in three hours for the kids to go sleading the next morning. A good temp is 27* or below. I guess this is my hobby when im slow haha.. (I also made a hydrogen generator for the heck of it, just to see if I could... And it made fire!) ohhh Im board.
