Creative Solutions in MacGyver: Science and DIY Hacks
Written on
Chapter 1: Trapped in the Compactor
In an episode reminiscent of a scene from "Star Wars Episode IV," MacGyver and Jack find themselves ensnared in a trash compactor. The aim here is for MacGyver to devise a clever escape, but Jack misinterprets the instructions, leading to unintended consequences.
To halt the compactor’s operation, MacGyver ingeniously uses a pole with his Swiss Army Knife (SAK) attached. He positions it precisely so the compressing walls force the knife through the structure, disabling a hydraulic pump that controls the compactor.
Important dialogue ensues:
MacGyver: "...if I hold the pipe perfectly normal."
Jack: "Dude. Nothing about this is normal."
As a result of Jack's blunder, he injures his arm. MacGyver notes, “I used a technical term that Jack didn’t understand.”
So, what exactly does “normal” mean in this context? In essence, it refers to being perpendicular to the wall. This is the same concept that physicists refer to when they talk about the force a surface exerts on an object, known as the "normal force."
Yes, while "normal" also finds application in geometry, it's clear Jack isn't in tune with those concepts.
Section 1.1: Understanding Spectrometers
Although it’s not a MacGyver-style hack, let’s delve into spectrometers.
My initial thought is a visible-light spectrometer, which functions similarly to a prism. When light passes through a prism, it disperses into various colors. By analyzing these colors, one can determine the source of the light. However, you likely wouldn’t find this type of spectrometer in a chemistry lab.
Another kind is the mass spectrometer. This device takes a gas of molecules, propels them into a designated area, and employs magnetic fields to alter their trajectory. By measuring how much the particles deviate, one can deduce their mass.
And let’s be honest—it’s just fun to say “mass spectrometer.”
Subsection 1.1.1: The Origins of Hacking
It's clear that MIT didn’t invent the act of hacking; humans have always had the ability to creatively solve problems, which is the essence of hacking. However, MIT might be credited with coining the term "hacking." The history behind this is fascinating. I recommend checking out the book "Hackers: Heroes of the Computer Revolution" by Steven Levy—it's a great read.
Section 1.2: Creating a Door Alarm
This isn’t a classic MacGyver hack, but rather one from a friend of his who creates a door alarm. The setup involves a simple circuit made from a small battery and a buzzer. The circuit connects to a clothespin outfitted with aluminum foil on its jaws and a piece of paper sandwiched in between. Since the paper acts as an insulator, the circuit remains open until the door is opened, pulling the paper out and completing the circuit.
It's a straightforward design that you can (and definitely should) replicate. Check out this video for a tutorial on how to build one.
Chapter 2: Ingenious Innovations
In one scenario, MacGyver crafts an electric whip using an extension cord. He cuts one end off, strips the wires, and plugs it into a wall outlet. Note: DO NOT attempt this at home. When the exposed wire ends make contact with a person, it delivers a shock—effectively turning it into a makeshift whip. While it may not produce the flashy lightning effects you might expect, it certainly looks cool.
DIY Centrifuge
This might just be the most impressive hack in MacGyver history—a DIY centrifuge that’s cost-effective and easy to construct.
What’s a centrifuge, you ask? It’s a device that spins at high speeds, allowing liquids to separate based on density through centrifugal force (yes, I used that term correctly). This is particularly useful in blood processing.
Here’s a glimpse of a professional centrifuge:
And here’s the DIY alternative—essentially made from string and cardboard. This simple version enables individuals in remote areas to process blood effectively, which is truly remarkable.
