We made a rat trap car for engineering class but it has to travel through sand, water, and an incline. It travels through the water and incline beautifully but can never get out of the sand. It just digs itself down and doesn't have enough power to get out of the sand trap, it is about 1 inch deep of sand, any help would be greatly appreciated.
I'm using large rubber K'nex tires, they are about 2 1/2 inches in diameter and 1/4 inch wide. I tried using two tires in the back to increase surface area but it made the car weigh to much and sink into the sand even more
