Transportation Security Administration agents regularly find some nutty things at airport security checkpoints. As we’ve discussed before, the TSA has a blog that regularly highlights some of these items, which range from loaded guns to inert hand grenades. But since blogs are very 2005, the agency has now branched out to Instagram.

Last week, the hashtag-happy TSA began using the service to share photos of some of the prohibited items agents have found at checkpoints. The first posted photo was meant to remind people not to bring fireworks onto planes (as our Lori Aratani discussed last week):

There were also others relating to unusual weapons agents found, including these knives:

Agents in Cleveland discovered a stun gun disguised as a pack of cigarettes:

And, of course, yet another inert hand grenade:

Even though Instagram recently added the ability to post videos, so far the TSA has stuck to just sharing photos. You can follow the TSA here.
