SNOWMAKING PROJECT-A+

not positive but im pretty sure they use a bit of nitrogen to get it cold quickly but other then that i think its just water

From what i remember the chemical is actually a bacteria but i don't remember what its called, has something to do with nucleation just like dust particles and rain.  that's all Ive got left, i hit my head that year.

contact your local resort would be my suggestion they'll probably have the real answers however you might just want to ask about snow making not tell the m about the environment part of it

Snow max is an additive that has been created from dead bacteria to start the chrystal structure in the freezing process. In nature, snow flakes are formed usualy around microscopic dust particles, thus creating a starting point for a chrystal. In the process of man made snow, water may be very clean (usual is in alpine areas) and the temperature has to cooler that the natural process to make any descent amount. By adding the snowmax agent (1x 50gram chip packet size per 10000 litres of water), it give the water droplet somthing to bond to, as its injected into the cold air using compressed air and a "snow gun".
The cooler the temperature, the less snowmax you will need to be productive, rite up to the point where you dont need any (-10 degrees C.) Snow max is non-toxic and has no environmental impact, but it is very expensive (up to $1000 per chip packet size)
Another interesting fact - 1 cubic cm of water will make 3 cubic cm's of man made snow at approx -5 degrees C.

anything that will lower the activation energy required for freezing.  i did a very similar project in high school.  I used albumen because its basically pure protein.  i used it also because snowmax is essentially protein.

everyone uses snowmax as an additive.. you look that up you win.

nailed it on the head... have this guy do your report.  he is spot on.

what he said.
