Coffee Can Ice Cream:

What You Need
3 pound empty coffee can w/ lid, 1 pound empty coffee can w/lid, 1 Pint of half & half, 1/2 Cup of sugar, Rock Salt, Ice 
How To Make It
Be sure empty cans are clean and free of any smell or residue of soap.

In small can mix half & half with 1/2 cup of sugar. I usually add a small amount of vanilla. You can also add any frozen fruit you like.  Put lid on and I duct tape it down.  You will need to remove this to stir so don't get carried away with it.

Place some Ice in the bottome of the large can.  Place the small can inside big can. Put ice down the sides and on top of the small can. Sprinkle about 2 tablespoons of rock salt onto the ice.  Place lid on and duck tape the lid on.  You will need to remove this once during this process to stir the contents of the smaller can and to add more ice and salt so put on enough to secure it but not so much that you can't get into it.

Now comes the fun!!!   If you are outside just gather the kids and let them play kick ball with the can.  If you are inside put a sheet or other large covering on floor and let them kick the can around the room.  After about 10 minutes check the small can.  If the ice cream isn't firm enough replace the lid and then redo the ice and salt and kick around for another 5-10 minutes or so.

Eat the ice cream and enjoy!

If you don't want to deal with the can's there is a new product out on the market that they made especially for this.  You can follow the link to check it out:
