A snow cannon (also called snowgun or snow maker) is a device used to produce snow artificially. The term artificial snow is mistakenly used for the produced snow; a more accurate term would be man-made snow. It relies on atomizing water with compressed air and allowing it to condense into snow. This device is often used by ski hills and ski resorts to supplement naturally occurring snow and extend the skiing season.

A snow cannon usually consists of a water nozzle onto which a high pressure jet of air is blown. Water flows from the nozzle and the jet of air causes the water to break up into tiny droplets (almost a fog). If the surrounding air temperature is near or below freezing, the droplets of water tend to evaporate and rapidly cool. This method only works when the ambient air is at 0 °C (32 °F) or lower.

If the humidity is low (10%), artificial snow can be made when the temperature is as high as 3.3 °C (38 °F). This is possible because of the rapid evaporation and evaporative cooling caused by the low humidity.

Homemade snow cannons are gaining in popularity. One can create a simple backyard snowgun, usable in temperatures below 0 °C.

its pretty hard to make artificial snow
if you freeze humidity with a sub zero hydrogen liquid it'll just decend to the bottom of your tank and possibly form ice

im guessing you can use a large a/c unit and use a different cooling liquid and modify it so it blows out your snow to the spot desired
you would need hi humidity in the air
and a modified a/c unit
try using liquid hydrogen instead of the usual freon in the a/c unit
and hope it doesnt blow up

or take the easy route and use stirofoam...
