Pucker up! Today we're unwrapping some sour citrus! First up, see how Lemonheads spin in giant pans and find out what color lemons really are! Then, indulge in a tart lemon treat at Village Inn, and watch as ReaLemon bottles thousands of gallons of lemon juice. And don't forget about limes! Tostitos is giving their chips an extra zing with a splash of lime juice, and Dreyer's frozen lime bars are a cool snack for a summer day.
