When you think of summer, you can definitely think of pink lemonade! And would you ever think that dirty laundry was behind its invention? Although pink lemons do exist, their juice is colorless and one of the numerous versions tells us why this particular lemonade was pink. In 1857, Pete Conklin was selling lemonade at the circus when he ran out of water and grabbed a tub of dirty water where a performer had just rinsed her pink-colored tights. He sold it as this new ‘strawberry lemonade,’ and since then, circuses have had ‘pink lemonade’ available to quench your thirst, hopefully reducing the percentage of dirty sock water.
