Another of July project our Pre-k class did. This was a hit with all the kids. Some turned out better then others but overall the craft was a success. Toilet Paper Roll Fireworks Stamp Craft for Kids - Great for a of July art project!
this one sounds even easier to make: bubble snakes = easy quick craft. Cut the bottom off water bottle. Put old sock over bottom and duct tape. Add food coloring for fun. Dip end in dish soap mixed with a little water
