Science : Balloon-Powered Mini Car

Tomorrow, is our project in making a balloon-powered mini car which is a part from Physics. First, yesterday, I watched some of the videos that was related to our project in order to have ideas in making our car. Second, the car must run for about 5 m. but we've tested our car for about.. 20 trials, so mean isn't it?. Our car run for only 3 1/2 m. Oh well, we reconfigured it again so that our car will run at the given speed. And the third one is.. you will find it tomorrow. I'll show you my car okay?

Here is one of the videos that I almost intend to imitate in making my car.(almost. okay?)
