Shake up the black spray paint and remove the cap. Make a black circle about twelve inches in diameter in the center of the page. Allow it to dry. Make a black square about four inches in diameter somewhere on the top of the circle. The bottom part of the square should be connected to the circle to make one shape, a circle with a small square attached to it.
Shake up the blue spray paint and remove the cap. Make a blue crescent-shaped area along the bottom edge of the circle, about seven inches long and three inches from the edge. Allow it to dry. Shake up the white spray paint and remove the cap. Make a couple of small circles somewhere near the blue crescent, about three inches from the edge as well. Allow all to dry. These areas will give depth and sheen to the bomb.
Make a five-inch blue "S" shape coming from the square that is on top of the bomb. This will be the wick of the bomb. Shake up the red spray paint and remove the cap. Make a star shape at the end of the wick that is not attached to the bomb, about eight inches wide. The star can have as many points as desired, and can overlap the bomb. This will be the sparks coming off the bomb's wick.
Shake up the yellow spray paint and remove the cap. Make a small area of yellow in the middle of the red star. Make the yellow area in the shape of the red star if desired, or just make it a circle.
