I remember when I watched this back when I was like 5 and I had no idea what the RU-vid auto play was, and so I saw it counting down to some video of a ceiling fan chasing a baby fan after I watched this video. I got scared of auto play after that. (But now I’m not anymore lmao)
"Mounted on each ceiling fan is one speaker and audio equipment. Sound is activated with a tilt switch (movement activated switch) when a fan starts spinning. The sound consists of a simple, hummed melody. Each 2 minute recording is endlessly looped while the fan spins - six fans spinning six melodies to create a chorus. The spinning speakers give the audio a tremolo effect (like the spinning speakers of the Hammond organ) which varies based on the fans speed. Each fan is moving in the same pattern (controlled by a computer) but the staggered start time of each fan results in an ever-changing pattern."
