Well, my partner and I haven't gotten together to speak about our balloon car. But we have an idea of how we are doing it. We are going to use wood from the tech room to make wheels and use 2 or 1 balloons to power our car. We are not really sure about what other materials we are going to use. As we know now, we want to win and get the marks but also learn more on how this is related to physics. (time, distance etc.)
to make our car stay on the ground , by using the "wood wheels" to hold down the car.
Then use light materials so that the car won't be has heavy,so that the balloons are able to push the car as far are we want. This is it, so far. we will keep updating..laters
