thanx for the replies. our timeframe for this is this coming wednesday, but this is suppose to be an extra curricular activity but our chem teacher said its 10 % of our final mark, so their are judges coming from outside who will judge our project. based on what marks they give our group thats our mark for the class. we have been thinking a lot on this project. this is the last place i came too. I wanted to make a product which is environmental friendly. Like last year we made a city which was fully powered by solar panels.
