Kianaki,
The folks at SnoShack may be able to provide you with a video (I am not sure).
What I do know is that the their machines provide a very fine snow that is like
pudding when you eat it. That is, it truly melts away on your tongue.
Yes, they are a bit pricy at $4,500.00 each; but when I can go through 100 twelve-pound
blocks of ice in a day without any machine trouble they are worth it to me.
