Sketch out a large teardrop shape in the middle of the paper with a pencil. Make it at least two feet high and a foot wide.
Shake up the red spray paint and take off the cap. Fill in the whole teardrop with the red spray paint. Allow it to mostly dry, waiting about a minute.
Shake up the orange spray paint and take off the cap. Make a smaller teardrop with the orange paint in the center of the red, leaving a three-inch border of red around it. The border should be on the sides and top. The orange can touch the bottom edge, if desired. Allow one minute to dry.
Shake up the yellow spray paint and take off the cap. Make an even smaller teardrop with yellow paint in the center of the orange, leaving a three-inch border of orange around it. The yellow may also touch the bottom, leaving the border around the top and sides. Allow a few seconds to dry.
Shake up the white spray paint and take off the cap. Make a small oval of white starting from the bottom of the teardrop, leaving most of the yellow uncovered. Allow it all to dry completely.
Finish off the fire by adding red "S" shaped (or snaking) flames coming from the upper portion of the red paint that is already there. Allow it all to dry.
Make several of these teardrop shapes of various sizes--all connected--to create a large fire.
