MacGyver's Ingenious Science: Explosions, Gadgets, and More

Chapter 1: Escape from the Server Room
In a tight spot, Mac and Riley find themselves trapped in a server room. Bozer discovers a concealed exit, but to access it, MacGyver must demolish a wall. Using two cans of disinfectant and a short piece of pipe, he improvises a solution. By inserting two wires into the pipe, he creates a spark when voltage is applied. This spark ignites the aerosol mixture, resulting in a powerful explosion. Essentially, it's a version of a potato cannon—minus the potato.
Riley humorously channels her inner Jack with a Star Wars reference: "Into the garbage chute, flyboy."
Section 1.1: Detecting Trackers
Before approaching a potential adversary, MacGyver needs to check for tracking devices. He crafts a detection tool using a PA speaker. Tracking devices emit various types of electromagnetic waves, including radio waves and visible light, which consist of oscillating electric and magnetic fields. To detect these, he employs a coil of wire that generates an electrical current when exposed to a changing magnetic field. However, this current is minimal, so an amplifier—like a loudspeaker—boosts the signal.
But there's a fun DIY twist! You can create your own magnetic field detector using a simple wire loop and a speaker.
Subsection 1.1.1: Tackling Tear Gas
One type of tear gas, phenacyl chloride (C₈H₇ClO), is not only effective but potentially more harmful than regular tear gas. To neutralize it during protests, one could cover the gas source with a traffic cone and seal it with a cloth soaked in water. This practical hack is based on real-life strategies used by demonstrators.
Section 1.2: The Concept of Nano-Trackers
While the term "nano-trackers" implies tiny devices measuring and transmitting data, it raises questions about their size. For instance, respiratory droplets from a cough, which can exceed 100 nanometers, are larger than these hypothetical trackers. While true nano-trackers aren't yet a reality, their potential for future development is intriguing.
Chapter 2: Powering Devices with Thermoelectric Generators
In scenarios where solar power isn't feasible, such as space missions, thermoelectric generators (TEGs) come into play. A TEG utilizes a heat source, typically radioactive, paired with two different metals to produce electricity through temperature differences. Interestingly, TEGs can also function in reverse; when an electric current is applied, they create a temperature differential, known as a Peltier cooler.
Returning to the world of MacGyver, how can they disable the nano-trackers? Normally, the skin's temperature is cooler than the body's internal temperature. However, if one could artificially lower the internal temperature, it might alter the current flow in the nano-trackers, effectively resetting them. While this concept seems far-fetched, remember, these trackers are purely theoretical at this point.
