# MacGyver Science: Ingenious Solutions During Quarantine
Written on
Chapter 1: The Context of Creativity
In this episode of MacGyver, which unfolds during the pandemic shutdown, we see an exceptional blend of ingenuity and humor. The portrayal of everyday challenges faced during lockdown resonates deeply with many viewers. From the chaos of toilet paper shortages to the comedic moments like MacGyver’s ukulele tribute to Dr. Fauci, this episode stands out as one of the finest in the series.
Notably, the characters wear face masks, with Bozer donning a mask, face shield, and gloves, which adds a layer of authenticity to the narrative. The interactions among Riley, Mac, and Desi are delightful, particularly Bozer's concern for his mother, which many can relate to. In this context, MacGyver's enthusiasm for fluid mechanics shines through as he remarks, “Fluid mechanics gets me HYPED.” The episode also features a playful homage to Hitchcock’s Rear Window, where Bozer observes the neighbors.
Now, let's delve into the fascinating science behind the episode.
Section 1.1: Hydraulic Trash Grabber
One of the clever solutions involves a hydraulic trash grabber. MacGyver needs to open a claw on a garbage truck to rescue Russ, so he improvises by puncturing the hydraulic line. This leak allows the claw to gradually open, facilitating Russ's escape.
But what’s the principle behind hydraulics? It's a system of two pistons connected by a hose filled with fluid. When one piston is pushed, the other moves in the opposite direction. An intriguing aspect of this system is that by utilizing a smaller piston on one side and a larger one on the other, a small force can generate a much larger force.
Here’s a simplified illustration of this concept.
The crucial factor is that the pressure within the fluid remains constant across both pistons. Pressure is defined as force divided by the area of the pistons. Therefore, a small force acting on a small area can be equated to a larger force acting on a larger area. However, it’s important to note that achieving a large force requires a greater distance to be moved on the smaller piston, akin to how simple machines function.
Subsection 1.1.1: Exploring the Night Sky
MacGyver reflects on a lesson from his grandfather about observing constellations. He states, “If you look at the stars from the Southern Hemisphere, the constellations appear upside down.” This observation is accurate, and I’ll illustrate this using a diagram featuring two individuals and a hypothetical constellation.
For someone in the Northern Hemisphere, the stars will appear one way, while for someone in the Southern Hemisphere, the view is reversed due to the spherical shape of the Earth.
Section 1.2: Clever Solutions with Everyday Items
In another inventive moment, MacGyver demonstrates how to release a zip tie without cutting it. By using a thin object to lift the ratcheting mechanism, this task can be accomplished effectively.
Also, he shows that older rotary phones can be utilized to dial numbers manually, demonstrating a resourceful way to communicate.
By using the rotary dial and shorting the microphone wires, MacGyver cleverly taps out a Morse code message.
Chapter 2: The Quest for Invisibility
Invisibility is a concept many dream of achieving, and while true invisibility is a complex endeavor, MacGyver showcases a clever workaround. By capturing an image of the background and projecting it onto a sheet, he creates an illusion of invisibility.
This process requires precise alignment, and wearing retro-reflective clothing can enhance the effect.
Section 2.1: The DIY Ventilator
At the episode's onset, MacGyver attempts to construct a ventilator using basic components, which initially fails. However, he later ingeniously repurposes a windshield wiper motor to compress a soda bottle, effectively creating a functional air pump.
This innovative solution is not merely fictional; a team at the University of Texas at Austin developed a similar low-cost ventilator using everyday materials, including a windshield wiper motor.
It’s remarkable to see a project inspired by MacGyver come full circle, highlighting the influence of creativity in problem-solving.
Here’s a fun sketch I created depicting MacGyver’s version of the ventilator.
While I can’t recall why I labeled it "S4," the creativity behind these solutions is undeniable.
