Spy Gadgets Durring WW2

During WW2 agents were armed with cool gadgets. We all have seen spy movies where they have very advanced technology. We have changed much in the technology department. In 40s a camera in a button on a coat with a huge shutter in the pocket, was pretty advanced compared to what a average camera looked like. A simple domino can hold a secret message behind its dots. An umbrella can projectile a sharp knife into a unsuspecting terrorist. Now a days we can use a camera size if a kernel. Write seemingly unbreakable codes into a grain of rice. A gun the size of a banana can shoot like a machine gun. Our technology is constantly changing and improving. Maybe in he future we will be using phones that are see through, or maybe drive a car that will run on corn and egg shells.
