Forget lemonade stands, ..... videos are the money makers.

MEXICO CITY – Authorities in Mexico's Gulf coast state of Campeche said Wednesday they are investigating how a porn video was made by sixth-graders inside their school.

State Education Department spokesman Omar Kantun said the video was apparently made in an empty classroom during recess in late April.

"It is real, the case is real, the video exists," Kantun said. "The Education Department is very concerned."
