3D printed food. Space-aged whiskey. And now, apples that fizz in your mouth straight from the tree. Such is the marvelous world we live in, where scientists dedicate their brilliance to making things once dreamed of in books. Thanks to Lubera, a Swiss fruit company, you'll soon be able to get your hands on a new variety of apple called the "Paradis Sparkling", which feels like a carbonated juice beverage when eaten. The fruit took years to get perfect, says the makers, who are now selling saplings to interested gardeners.
