Question

Wipe the board with a duster and then tap the duster against the table. What do you see?

Short Note

Solution

When we wipe the blackboard with a duster, we see particles of chalk powder settling on the duster. When the duster is tapped against any hard surface, these particles move out of the duster and settle elsewhere. The chalk powder spreads everywhere.
