A Picture is Worth...Square Watermelons
Here's an Internet oldie but goodie shipped directly from Japan. Don't worry, anti-GMO types, these watermelons didn't have their DNA tinkered in any way—they derive their unique cuboid shape from the tempered glass boxes the farmers grow them in.
While they may appear little more than novelties, square watermelons serve a more practical purpose: They save space during packing and storage, for one, which means less fuel can be used during transport. Plus, watermelon lovers can slot them neatly into their refrigerators without too much hassle.
Just one caveat: Each melon will set you back 10,000 yen, or about US$83, a price that is almost 10 times that of a regular ball-shaped watermelon.
