I made one once using a pressure washer as a pump, going to a high velocity/speed fan with a ring around the exit with small holes for he water to come out. It worked really well, until the pressure washer crapped out.
Careful now the Cape Cod Commission might want you shut down for large capacity snowing device.
You might also be labeled a racist by the racist herself Elenita Muñiz .....
Too funny one of my girlfriendsdaughters car kind of got covered with a little errant snow..... She just texted me people weregathered around her car in a parking lot waiting for her to come out of the store to see where it had been snowing...Not sure if any were from the Cape Cod Commission though
Small cheapo pressure washer 1600 PSI from Harbor frieght $89...Small cheapo air compressor I got at Walmart years ago 2.5 CFM @ 90 PSI.
It doesn't take much to produce a lot of snow......
