We worked very hard to think about how the different parts of our car would be made. We then tested our cars to see how far they would travel using the balloon to make them move. We came up with some very interesting results and found out that the balloons only worked to power the smaller, lighter cars not the heavier ones.
We also thought of some other interesting questions to investigate if we were to do this experiment again such as what would happen if we used more than one balloon? We also wondered how our results would change if we used a stronger material for the axles. We had great fun and were really focussed when carrying out the task.
