The feed is essentially a gallery of some of the craziest items people try to get past security checkpoints. There's no shortage of material—the TSA claims an average of 40 firearms (often loaded) are seized at checkpoints every week. Nine-bladed super knife? Grenade? Everything you need to assemble a bomb? Yes, all that and more. Everything that's seized is photographed for posterity, if not the spectacle, and then shared on social media to show people what's what.

"We're just using a new mechanism to reach an audience with Instagram," says TSA Press Secretary Ross Feinstein. "We're not trying to make a statement that people are trying to do anything nefarious with these items. We're just trying to alert people that these are still prohibited items."

In addition to the guns and other prohibited items, the TSA feed also features adorable bomb-sniffing dogs, spotlights various employees and calls out programs and promotions.
