One Alabama school principal wants students to have a way to fight back should an intruder enter the school. However, with a strict no gun policy in the school district, the principal is turning to canned food as a weapon of choice.

According to ABC News, W.F. Burns Middle School Principal Priscella Holley sent a note home with students on Friday requesting that canned goods be sent to school with each child. The letter detailed that the school’s “intruder policy” will remain the same with one major change, each child will be armed with a canned food product which they can throw at the intruder to “stun” or “knock out” until police arrive.
