Miami airport floods with mysterious lime green liquid dripping from ceiling

Is it Independence Day or Halloween?

Travelers going through the Miami International Airport on the Fourth of July were treated to a nasty surprise when a strange lime green fluid began leaking through the ceiling and flooding a hallway.

Airport officials said the leak, which was not hazardous, came from a pipe in the facility’s Concourse G at around 9 a.m. Thursday.

Images shared by MIA staff showed the hallway covered in the fluorescent liquid, with custodians closing off the area and working to clean up the mess.

“The valve feeding the pipe has been closed to stop the leaking, and cleanup efforts are now underway,” an airport spokesperson said in a statement. 

Footage shared by passengers showed close ups of the liquid cascading from the walls, with the lime-colored mess rendering an entire waiting area inaccessible.

Officials said the mysterious ooze was actually water with a green dye that came from the building’s air conditioning system.

The green dye is used to easily discover a leak and trace it back to its source, the airport rep said in the statement.
