Changes we made to Cardboard Car

Last time, we discovered that having three wheels was very inefficient, as the car was unbalanced, slow, and wobbly. We also discovered the car was very big when compared to other cars. So, this time we cut the car into a smaller rectangle. We also added another wheel, making it four wheels total.

Last time, we also discovered that the wooden dowels were very weak. So, this time, we added PVC pipes and put the wooden dowels inside the pipes. The PVC pipes were too long, so we had to cut them. Lastly, we made two new wheels, as some wheels were damaged due to the test from last year. This time, we made sure to drill the holes of the wheels at the center of the wheel.
