Science project

Now days I am feeling boring that's why I have decided to make a science project. Finally I started making a motorboat which will run by wind energy. What I have done is that I have taken two aluminum trays and at the end I have made two holes in which two straws are going at the end of straws .I have fitted two balloons and on other side I have put two rubber band to close it. When I need to make the boat run I will take out the rubber band and it will run because of wind energy.
