Why do you hold to operate box fan next to the "feet" attached to them?
Answers: The tremor that occurs while the lover is on can make it fall down over. Older fans be made of metal which gave them greater mass and stability. I have also notice the fans keep hold of getting thinner and thinner, therefore need the feet lately to stand up.
The feet are to maintain the fan from tipping over from the unenthusiastic force the fan creates when pushing the heavens

Bottom line is nouns pushing one way will wreak the fan to push the other approach and tip over
