Square Watermelons! It's true.

It's not a fad. The technique actually has practical applications. "The reason they're doing this in Japan is because of lack of space," said Samantha Winters of the National Watermelon Promotion Board in Orlando, Florida.

A fat, round watermelon can take up a lot of room in a refrigerator, and the usually round fruit often sits awkwardly on refrigerator shelves. But clever Japanese farmers have solved this dilemma by forcing their watermelons to grow into a square shape.

Farmers insert the melons into square, tempered glass cases while the fruit is still growing on the vine.

The square boxes are the exact dimensions of Japanese refrigerators, allowing full-grown watermelons to fit conveniently and precisely onto refrigerator shelves.

But cubic fruit comes with a price: Each square watermelon costs 10,000 yen, the equivalent of about $82. Regular watermelons in Japan cost from $15 to $25 each.

Japanese farmers have perfected the art of growing square watermelons, but they aren’t about to reveal their secret process. When a square watermelon sells for $82 who can blame them.
