One of the reasons people love Bubble Wrap is the satisfying "POP" it makes when you squeeze a bubble. From a distance, one could almost mistake it for a pistol going off.

In fact, that's what a college student in suburban Philadelphia thought was happening when she heard a burst of popping sounds Monday.

"The situation appears to be one where a female student in the dorms of Eastern University heard what she thought were shots fired. She diligently called 9-1-1," Jamie Bilella, a vice president Valley Forge Military Academy & College, told NBC10.

The student's dorm is located on the campus of the military academy.

Authorities immediately locked down Valley Forge Military Academy and Eastern University, which is less than a mile away from the academy. Nearby Cabrini University was also locked down . But police searches of the schools turned up no weapons or evidence of weapons being fired.

Bilella said that further investigation indicated that the source of the sounds was likely Bubble Wrap being popped.
