A bunch of kids briefly caused the closure of a D train platform in the Bronx when they got sick on their way back from a Central Park pool.

The group of 11 youngsters were coming back from a summer outing at the Lasker Pool when eight of them simultaneously vomited at the Fordham Road station.

The FDNY received a call for a hazardous material, but a station worker had cleaned up the mess before firefighters arrived. Emergency personnel transported the sick kids to Saint Barnabas Medical Center.

Train service was never delayed and it only took a few moments to clean the vomit off the platform.

It is still unknown what made the kids sick.
