Milk Carton Ice Block Hack

Another game-changer for me! Not only is this much less expensive than buying bags of ice, they last much longer in the ice chest. Just rinse them out with a drop of unscented dishwashing liquid and save them for a rainy day. Fill them a little over 3/4 full with tap water and freeze them overnight for the next camping trip. Don't forget the ice pick to make ice chips for the drinks.
