The Salt Water Fuel Cell Monster Truck Kit is equipped with four-wheel drive mechanical construction. It easily handles different types of terrain by its twisted car body design. The transparent case design allows children to see the rhythm of the piston in vertical or horizontal position. Each monster wheel can change its angle individually and the truck can change its height and shape. Powered by salt water, this is an outstanding science fair project or holiday gift.
