A lime green liquid rained down from the ceiling and drenched the floor of Miami International Airport and disrupted travel on the Fourth of July.

The initially mysterious liquid covered tiles around seating areas of terminals on Thursday morning and caused some sections to be cordoned off with caution tape.

‘That is literally insane,’ someone is heard saying in a video shared on X (formerly Twitter).

Another person is heard exclaiming: ‘Oh my god, look at the airport. What happened?’

The liquid that appeared around 9am turned out to be ‘water from the A/C system with a green dye in it, so that if there is ever a leak it can traced to its source’, Miami-Dade Aviation Department Communications Director Greg Chin told the Miami Herald.

It affected Concourse G, gate G7, which is used by Bahamasir, Porter Airlines, Southwest, Spirit and WestJet.

The mess was cleared by 10.30am.

‘We would like to thank our passengers in Concourse G for their patience & understanding this morning,’ wrote the airport on X (Twitter) shortly before noon.

‘Crews were immediately dispatched to investigate and it was determined that the liquid from the leak was not hazardous.’

The airport stated that no flights were delayed due to the liquid leak.

Authorities said that the liquid was glycol and is only hazardous if consumed, reported the Daily Mail.

Glycol is a ‘useful industrial compound found in many consumer products’ like antifreeze, ballpoint pens, solvents, plastics, paints and cosmetics, according to the Centers for Disease Control and Prevention.

The Transportation Security Administration has predicted it will screen a record number of travelers this Fourth of July weekend, with more than 3million expected on Sunday. Sunday is also forecast to be the busiest travel day of the summer, with more than 6,500 flights scheduled.

As many Americans travel by air or land, the FBI and Department of Homeland Security also issued bulletins about large July 4 events being potential ‘attractive targets’ for attacks.
