Brain Teasers
Dirt
A guy who was cleaning his house realized his vacuum uses more power than a box fan, so he got creative and grabbed a lawn mower bag and the hose from the vacuum and taped those to the front and back of his box fan respectively. However, when he went to use his new contraption, the dust never went into the bag. Why is that?
Answer
Box fans don't suck. Since they lack the sucking power of vacuums, it can't suck the dirt into the mower bag. Any dirt that happens to make it in would end up on the fan parts and wouldn't make it into the bag.Hide Answer Show Answer
