My prototype was on "Water Bottle Rocket" which could be used to increase the fuel efficiency of rockets and jets which take a lot of fuel and energy to take off.
My questionnaire is administered to the people who would consider my model as something which could practically be used to improve the fuel efficiency. Their suggestions, replies, and answers are more than welcome which would help me brush up my model more.
I woul like to adminster the questionnaire face to face. Online is good but when we meet people directly we become more acceptable to their thoughts and ideas. Also if they would want to give some extra tweaks or suggestions to help me make my model, it would be easier in a face to face conversation.
From the questionnaire, I would extract many things. Each of my question is asked to answer a certain thing about my model. From my third question, I would get to see my creation from the eyes of someone else which would help me make it better and improve it to perfection.
