Not forgetting our teacher-mentor:
Mdm Leow Ree Yin
This idea was derived when we noticed that our maths teacher Mr Png was writing these formulas and when he rubbed it off in a hurry to conserve time,patches of ink still remains and may sometimes affect the actual writings and cause misunderstandings.So we plan to come up with a duster that can prevent that and at the same time bring convenience to the teachers.
So,tha-dah, we came up with this idea of using alcohol which cleans off faster and cleaner than water and other ordinary dusters.
Please note that alcohol is only used for pilot test
