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 colourless. In 1857 Pete Conklin was selling lemonade at the circus and ran out of water and grabbed a tub of dirty water where a performer just rinsed her pink-coloured tights. He sold it as this new ‘strawberry lemonade’ and since then circuses since then would have their ‘pink lemonade’ available to quench your thirst, hopefully reducing the percentage of dirty sock water.
