The duster actually works like a normal duster except that alcohol is filled within it and the alcohol will soak through the fabric to be wiped on the whiteboard.
There would be some buttons to press to release the alcohol and another to reveal an opening for the reflilling of alcohol.
*NOTE:This short instruction manual is only workable to a certain extent as the whole process of the prototype is not completed.
*NOTE:The shortness of this portion reflects one of our goals of making it user-friendly

This will be very challenging to us on how to reduce the cost to as low as possible.The costs as follow are only for the prototype.
| Materials | Costs |
| Whiteboard Duster | $1.50 |
| Alcohol | $1.95 |
| Strap | $0.60(Estimated,did not buy it) |
| Container(plastic + cardboard) | $0.80(Estimated,did not buy it and consists of few materials) |
| TOTAL | $4.85 |
As you can see,the price is still steep and we will be reducing this even further in stages.
Reasons for Choice
The following would be the reasons why we are choosing this materials
Whiteboard Duster(Plastic)-----This is because it is more durable and lasting.
Denatured Alcohol -----This is one of cheapest alcohols and is an solvent of ink.Morever,it evaporates faster.
Container(plastic and cardboard)----The cardboard gives the rigid skeletonof the container.The plastica prevent the alcohol to soak into the cardboard
