Color-Changing Iced Tea – Very Blue & Very Drinkable!

There's nothing better on a hot summer afternoon than a tall, cool glass of blue iced tea. Wait a minute... blue?! Yup, that's right. But this isn't some cheap trick with blue food coloring — there's nothing but all natural ingredients in this beverage. And when you stir it, it even changes from blue to purple. Skeptical? Try it out for yourself!

The secret ingredient can be found in Butterfly Pea Flower Tea, a caffeine-free herbal tea from southeast Asia. The special thing about it is that it changes color depending on the pH level of the fluid it's mixed with. For example, adding some lemon juice or Sprite turns the tea purple. Try out your own combinations and see what kind of interesting hues you can create!
