As if the Philadelphia Experiment wasn't enough, the citizens of Philly will now be adding a new item to their list of conspiracy theories.
The Huffington Post shared an image of what some are calling "radioactive fluid." Wait. Radioactive fluid? Going down the sewer system? Did someone say "Teenage Mutant Ninja Turtles!"?
Hopefully everyone in Philly kept their pet turtles in the safety of their tanks.
Not to worry though, the mysterious substance won't mutate your pets into martial arts fighting machines (at least not yet anyway).
Redditors have stated that the substance is actually a dye put in the water to measure how deep a particular sinkhole is.
