Ep 14. Dead Drop Danger

In "Street Science" season 2 episode 14, titled "Dead Drop Danger," Kevin Delaney and his team continue their mission to uncover the science behind everyday objects and occurrences. This time, they focus on the world of espionage and hidden technology.

The episode explores the concept of dead drops, which are covert locations where people can exchange information without ever meeting face to face. The team sets up a dead drop of their own, creating a hidden compartment in a park bench where they can stash a message for their fellow scientist, Tory Belleci. They then set out to devise a way to quickly and discreetly retrieve the message when Tory leaves his own signal.

To aid in their mission, Kevin calls upon a master of espionage: Jonna Mendez. Jonna is a former CIA officer who specialized in disinformation and covert operations during the Cold War. She shares her insights into the art of spycraft, from the use of hidden cameras and microphones to the creation of disguises and fake documents.

Kevin and his team also explore the science behind some other spy tools and tactics. They examine the properties of infrared light and how it can be used to detect hidden fields, like those created by hidden cameras or microphones. They also experiment with laser microphones, which can pick up audio vibrations from a distance, allowing spies to eavesdrop on conversations without being detected.

The team also studies the science behind encryption and code-breaking. They examine the Enigma machine, used by the Germans during World War II to encrypt their messages. Using a replica of the machine, they attempt to crack a coded message, revealing the intricate mathematics and pattern recognition needed to break complex ciphers.

Finally, the team showcases their final dead drop creation, which uses principles of electromagnetism to create a secret, wireless channel of communication between Tory and the team. By placing a magnet near a coil of wire, the team creates a small electrical current that can transmit a signal to a receiver hidden in a nearby tree. Using this method, they are able to quickly and discreetly exchange messages without anyone suspecting a thing.

Overall, "Dead Drop Danger" offers a fascinating look into the world of espionage and hidden technology. With the help of Jonna Mendez, Kevin and his team explore the science behind some of the most iconic spy tools and tactics, revealing the intricate techniques and technologies that have helped shape the course of history.
