What you do:
- Ask your mom not to clean the ceiling fan in your room for two to three weeks
- Observe the blades of the fan at the end of this period.
What you find:
That most of the dirt collects on the leading edges of the blades.
Why does this happen?
Static electricity develops on the blades of the fan when they are in motion due to friction with the air The static electricity attracts dust particles. As the edges of the blades are the first to come into contact with the surrounding air, more dust collects on them than on the other parts of the blades.
