Nowadays, schools use blackboard for teaching. However, the dusters for cleaning are often inconvenient to use. Duster produce a lot of respiratory particles which is unhealthy for teachers or students when they intake a lot. Moreover, after using the dusters, our hands will be very dirty. Therefore, our aim is to invent an ideal duster which is multi-functional and at the same
time, easy to use. All in all, our duster improves the quality of lives.
