Play and Freeze Ice Cream Maker

Whether this is for an emergency or not, I wanted to share it. We tried our ice cream maker last year on a camping trip and it worked out great. It did not require a lot of ingredients and it froze in about 15 minutes or so. All it requires is a little work out from you, no electricity. Keep boxed milk, sugar, vanilla, ice and salt rock around and you have ice cream in about 20 minutes.
