CIA operatives may not use jetpacks or laser-powered watches, but they do have a few tricks up their sleeves.

At the CIA Museum in Washington, DC, you can get a glimpse of the gadgets used in past spy missions.

The agency has declassified 600 out of some 20,000 objects used by CIA operatives throughout history, museum director Toni Hiley tells Tech Insider. Current operatives are constantly looking to old gadgets to build new ones.

"Revisiting technology is something we always do in the world of espionage," Hiley says. "There's no such thing as technology that's too old for operations."

From concealed cameras to flies on the wall, here are the 11 most fascinating gadgets from the collection.
