Ice Cream in a bag

Notes:Make sure to wrap the bags inside a towel to protect hands. 

Also, when my son made this at school, he said that the small bag had a tendency to open during the shaking process, which made the salt get into the ice cream and made it pretty disgusting.  So, just be sure to seal your bags completely and before you take your first bite, be sure that the bag didn't open during the shaking process.  Have fun!
