The information given in the link you provided makes it sound anything but fun, and further defines a lot of liabilities.  If you can find coffee cans, you don't have to buy them.

A while back someone asked about how to get ice cream while camping.  At that time, I just suggested a small, manual crank ice cream freezer like I have, and which I have used while camping on quite a few occasions.

Here is another way, if you can find the coffee cans.  I have coffee cans that are as much as 30-40 years old that I use for various things, but I don't see them in stores nowadays, not even the ones described in this article.  Of course, you would need a surface that the cans would roll on, also, not always available when camping.
