We've got a LOT of frozen milk stockpiled at our place right now.
On these super cold days cases of milk often freeze in the time it takes to drive from our house, where we store the milk (a classy home décor) half a mile down the road to where the pigs are waiting to slurp it down. While we wait (months??) for the weather to warm, and the milk to thaw, our kids have found a good use for the solid ice blocks.
Here you have the milk-gloo (igloo made of crates of frozen milk).
