No, this isn't a Photoshop sham. That's real corn with rainbow-colored kernels. They are called Glass Gem Corn, a variety especially bred by Oklahoma farmer Carl Barnes, Try this in your smoothie ! Barnes is a part-Cherokee farmer, the report said, who would, every so often, find corn cobs with kernels that looked like glass beads of unusual color in his crop. He would save those seeds and then cross-breed the corn for many years. Thus was Glass Gem Corn born.
