Collect the cardboard egg cartons ahead of time (one carton per child).
To prepare each egg carton for the project, place the egg carton lengthwise and cut a 2-inch by 2-inch section out of the second and third cups on the top portion. You may also choose to cut off a small diagonal section from the first cup. The point of the cuts is simply to make the carton more closely resemble the shape of a fire truck.
Also, cut two wooden craft sticks in half for each project.
