These turn out great and really look like fireworks. These are easy enough to make that young children such as preschoolers, and children in younger grades can even make them. Just use watercolors or food dye to color coffee filters red, white, and blue. Then let them completely dry on paper plates or trash bags. Then cut strips all around the circle coffee filters. Leave the center of the coffee filters un-cut. Then use chenille stems (pipe cleaners) to poke thru the center of the coffee filter. Twist it down at the top to keep the stem intact. Now pull the cut sections all around the stem to look like fireworks...pulling some down, some up, etc.
