The video begins with a close-up of a Logitech G502 gaming mouse sitting on a wooden desk, its blue LED logo illuminated. A hand brings in a can of compressed air with a red extension nozzle straw aimed directly at the mouse's scroll wheel. At around 00:08, a stream of compressed air is sprayed onto the wheel, causing it to spin at hyper-speed and emit a high-pitched, screaming whir.
At 00:15, the camera pans up to show a monitor running Counter-Strike: Global Offensive. As the jet of compressed air continues to spin the scroll wheel relentlessly, the game interface responds to the frantic stream of inputs, rapidly cycling weapon commands on screen while the air can continues to hiss.
It is a classic, chaotic clip demonstrating the absurd results of combining a free-scrolling mouse wheel with canned air. Seeing the high-frequency physical spinning translate directly into in-game madness on CS:GO makes for a brief but hilarious bit of PC gaming comedy.
