Of the three candidates, this is the clear pick. The Procreate-to-Cricut tutorial is a software workflow walkthrough rather than fabrication, and the ultrasonic mist maker entry is a #shorts video — exactly the format the curation rules tell us to skip. The air-powered car, by contrast, is a proper longer-form build video from a channel dedicated to approachable maker projects.

The build itself is a great vehicle (pun intended) for teaching Newton's third law — compressed air escaping a nozzle pushes the car forward with an equal and opposite reaction. Projects like this are gold for classrooms, homeschoolers, and parents looking for a weekend build, because they require only household materials (bottle caps, skewers, a balloon or syringe for the air source) and the physics is visible in real time. You can tune the wheelbase, axle friction, and nozzle diameter and immediately see the effect on travel distance.

The description does mention a "steam-powered cork gun" in addition to the car, which suggests the channel may cross-pollinate build ideas — worth noting that the title and description are slightly mismatched. Still, the underlying skill set (drilling straight axle holes, reducing rolling friction, sealing a pressure vessel) transfers directly to dozens of other small-scale engineering builds.
