OK, no need to panic just quite yet but WTF, pink snow! Hilltown police were called to an area in Philadelphia after reports of pink snow everywhere, on roofs, grass and trees. The police virtually said OMG, WTF and rang Federal Aviation Administration to see if one of their planes were to blame. Last time I looked urine wasn’t pink, unless of course there were a lot of people with urinal tract infections flying! Anywho, while the police were scratching their heads in wonderment one of the neighbors son’s Googled and came up with a logical explanation. Watermelon snow. Yes, that is a name given to an algae called chlamydomonas nivalis that contains a red pigment. Occasionally when covered in snow it will try and make its way towards the sunlight causing the snow to color.
