Square Watermelons

A round watermelon can take up a lot of room
in a refrigerator and the usually round fruit
often sits awkwardly on refrigerator shelves.
Smart Japanese Farmers have forced their watermelons to grow into a square shape by inserting the
melons into square, tempered glass cases while the fruit is still growing on the vine.
