This neck fan isn’t your typical wearable fan. We mentioned above that it features an aerodynamic (khí động lực) design, but let’s talk about that some more. This component of The Airable moves the air from your collarbone (xương đòn) area all the way around your neck. So it doesn’t just create a breeze where the fans are located but around the entire neck. This cools you down faster. The fans also turn 180 degrees, which makes it possible to position them the way you want.

But to turn 180 degrees revealed a startling scene of vacancy and militarization (quân phiệt hóa), where service members guarded a National Mall empty but for 200,000 flags whipping in the chilly winter wind. They were planted there to represent the crowd that couldn’t attend because of the surging coronavirus pandemic, which has killed more than 400,000 people in the U.S. alone.

The students react to the challenge in predictably wide-ranging ways. Some, worried that even a slight breeze from the building’s air conditioning system could push a civilian balloon into the robot’s metal spear, start by teaching their miniature (vật thu nhỏ, bức tiểu họa) tanks to turn 180 degrees away from any civilian detected, forfeiting the opportunity to kill the enemy. Others program their tanks with a more gung-ho approach, sometimes leading the machines to slay balloons — including “civilians” — with abandon.
